The cost of a bottle of water is (w – 1) cents.
The cost of a bottle of milk is (2w – 11) cents.
A certain number of bottles of water costs $4.80.
The same number of bottles of milk costs $7.80 .
Find the value of w
Answer:
w= 25
Step-by-step explanation:
Cost of water= (w -1)¢
Cost of milk= (2w -11)¢
Let the certain number be x.
x(w -1)¢= 480¢ -----(1)
x(2w -11)¢= 780¢ -----(2)
From (1):
wx -x= 480 -----(3)
From (2):
2wx -11x= 780 -----(4)
(3) ×2:
2wx -2x= 960 -----(5)
(5) -(4):
(2wx -2x) -(2wx -11x)= 960 -780
Expand:
2wx -2x -2wx +11x= 180
9x= 180
Divide both sides by 9:
x= 180 ÷9
x= 20
Substitute x= 20 into (3):
w(20) -20= 480
20w -20= 480
20w= 480 +20
20w= 500
w= 500 ÷20
w= 25

What’s the inequality & the solution to the inequality is ..
Answer:
x = 5.
Sorry if you didn't mean find x and I have no idea about the inequality stuff.
Step-by-step explanation:
We can do a reverse equation in steps. So the first thing we'll do is..
49 - 9 which equals 40.
Then we should do a division since the opposite of multiplication is division.
40 divided by 8 = 5.
To check that we do 5 x 8 = 40 + 9.
Hope that helps. x
Answer:
See below
Step-by-step explanation:
9 + 8x [tex]\geq[/tex] 49
Subtract 9 from both sides
8x [tex]\geq[/tex] 40
Divide by 8
x [tex]\geq[/tex] 5

how do i tell if an angel is comolentery, supplmentsry, or neither? I was not at school the day they showed me this?
Answer:
supplementary angles - two angles are supplementary when they add up to 180 degrees (a straight line)
complementary angles - two angles are complementary when they add up to 90 degrees (a right angle)
hopefully this helps! :)
Answer:
1. complementary
2. neither
3. supplementary
4. complementary (x = 6)
10x + 30 = 90 x + 3 = 9 x = 6
5. supplementary (x = 20)
4x + 40 + 3x = 180 7x = 140 x = 20
6. x = 50.5
2x + 79 = 180 2x = 101 x = 50.5
Step-by-step explanation:
When the measurement of the angles adds up to 90 degrees, the angles are complementary. When the sum of the angles is 180 degrees, then they are supplementary.

Anu and Aji solve an equation. In solving Anu commits a mistake in constant term and finds the roots 8 and 2. Aji commits a mistake in the coefficient of x. The correct roots are (a) 9,1 (b)-9,1 (c) 9, -1 (d) -9.-1
The correct roots of the equation are (a) 9 and 1
From the complete question, their mistakes are:
Anu
Roots: 8 and 2Wrong constant termAji
Roots: -9 and -1Wrong coefficientA quadratic equation is represented as:
[tex]ax^2 + bx + c = 0[/tex]
Where:
[tex]\alpha\beta = \frac ca[/tex] --- product of roots
[tex]\alpha + \beta = -\frac ba[/tex] --- sum of roots
Anu made a mistake in the constant term, so we consider the sum of roots
[tex]Sum = 8 + 2[/tex]
[tex]Sum = 10[/tex]
Aji made a mistake in the coefficient, so we consider the product of roots
[tex]Product = -9 \times -1[/tex]
[tex]Product = 9[/tex]
The possible equations from the above sum and products are:
[tex]x^2 + 10x + 9 =0[/tex].[tex]x^2 - 10x + 9 =0[/tex].[tex]x^2 + 10x - 9 =0[/tex].[tex]x^2 - 10x - 9 =0[/tex]Of all the above equations, the most likely equation is [tex]x^2 - 10x + 9 =0[/tex], and it has a root of 9 and 1
Hence, the correct roots are (a) 9 and 1

Maya’s bird feeder holds 1/2 of a cup of bird seed. Maya is filling the feeder with a scoop that hold 1/6 of a cup of birdseed how many scoops will maya put into the feeder
Answer:
3 scoops
Step-by-step explanation:
If the bird feeder holds 1/2 cup, and Maya is filling it with a scoop that holds 1/6 cup of birdseed, then Maya will need 3 scoops of the 1/6 cup scoop.
1/6 + 1/6 + 1/6
= 3/6

don't worry i help you now
Step-by-step explanation: Let's come up with points that would be on the graph of a str. line:
(0, 1/4), (1, 1 1/12), (2, 1 11/12), (and so on).
Assume that this is a line, a str. line, and not a curve.
The slope of this line is
1 11/12 - 1 1/12
m = ------------------------ = 10/12, or 5/6.
2 - 1
We now have the slope and y-intercept: slope = m = 5/6; intercept = 1/4.
The line is then y = (5/6)x + 1/4.
To answer this question, substitute 4 for x and calculate y:
y = (5/6)(4) + 1/4 = 20/6 + 1/4 = 40/12 + 3/12 = 43/12 inches.
That's 3 7/12 inches.

Step-by-step explanation:
Sam currently 100 followers on TikTok, and gains 8 subscribers a week. Alex currently has 220 followers, and gains 3 followers each week.
Part A: Set up a system of equations to shows each person's subscribers. (2 points)
Part B: After how many weeks will Sam and Alex have the same number of subscribers? (1 point)
Part C: How many subscribers will Sam and Alex have when their subscriber count is equal? (1 point)
Part A: The system of equations to shows each person's subscribers is:
S = 100 + 8x
A = 220 + 3x
Part B: Sam and Alex will have the same number of subscribers after 24 weeks
Part C: Sam and Alex will have 292 subscribers when their subscriber count is equal
Let the number of weeks be x
The initial number of followers that Sam has = 100
Sam gains 8 subscribers every week
Let the total number of subscribers that Sam has be S
The equation that represents Sam's total subscribers is:
S = 100 + 8x..................(1)
The initial number of followers that Alex has = 220
Alex gains 8 subscribers every week
Let the total number of Alex's subscribers be A
A = 220 + 3x....................(2)
If Sam and Alex have the same number of subscribers:
S = A
100 + 8x = 220 + 3x
8x - 3x = 220 - 100
5x = 120
x = 120/5
x = 24
Sam and Alex will have the same number of subscribers after 24 weeks
To find the number of subscribers that Sam and Alex will have when their subscriber count is equal, substitute x = 24 into equation (1)
S = 100 + 8x
S = 100 + 8(24)
S = 292
Sam and Alex will have 292 subscribers when their subscriber count is equal

Graphs are used to represent functions, and vice versa
The value of y for q = 360 degrees is 0
The sine equation is given as:
[tex]y = \sin(q)[/tex]
When q= 360 degrees, the sine equation becomes
[tex]y = \sin(360)[/tex]
At q= 360, the graph crosses the x-axis.
i.e. the value of the graph is 0.
So, the sine equation becomes
[tex]y = 0[/tex]
Hence, the value of y for q = 360 degrees is 0

Step-by-step explanation:
I am sorry to say so, but the other answer is rubbish.
there is no difference.
both mean the same thing : f(x) × f(x).
f(f(x)) is exactly what that expresses (f of f(x)).
another way of writing for this would be (f○f)(x).
but never ever f²(x).

A 20-foot piece of metal is cut INTO pieces that each measure 1 1/4 feet. How many pieces are there after the cut?
A. 16
B. 25
C. 18.75
D. 5
Answer:
I believe the answer is 16 Don't get mad if incorrect just trying my best
Answer:
A. 16
Step-by-step explanation:
If a 20 ft piece of metal is cut in 1 1/4 feet pieces you would divide the total length (20) by each of the pieces length (1 1/4) to find the answer. 20 ÷ 1 1/4 = 16.

tickets at a particular movie theater have different rates for adults and children. On tuesday the theater sold 8 adult tickets and 9 tickets for 174. the next day the theater sold 5 adult tickets and 7 children tickets for 117. What is the price for the adult ticket and the price for the child ticket
Answer:
Adult = $15 pp
Child = 46 pp
Step-by-step explanation:
Let A and C be the price of Adult and Child's tickets, respectively.
We can set up equations for each of the two days, Tuesday and Wednesday. Each equation adds the totals paid for the two ticket levels and set it equal to the total income for that day:
Tues: 8A+9C=174
Wed: 5A+7C=117
We have two equations and two unknowns. Let's manipulate one of the equations in a way that allows us to eliminate one of the two variables, A or C. [One can also solve either equation to isolate one of the variables, and then use that in the second equation.]
I chose to multiply the first by 5 and the second by -8, in order to make the coefficients for A the same value in both equations, but opposite in sign:
Tues: 40A+45C = 870 [Multiply by 5]
Wed: -40A -56C = -936 [Multiply by -8]
-11C = -66 [Add the two equations]
C = 6 [Ta Da. Now use this price for a child's ticket in either of the original equations to find the cost of an adult ticket.]
8A+9C=174
8A+9*(6)=174
8A+54=174
8A = 120
A = 15
====
Use these two prices in the original equations to see if they indeed add up to the correct totals for each day.
Total Sales
Price Tues Wed Tues Wed
A 15 8 5 120 75
C 6 9 7 54 42
174 117 174 117 [The prices are correct]
Adult is $15 and child is $6
