Answer:
Step-by-step explanation:
6x - 9y = 12
subtract 6x from both sides
-9y = 12 - 6x
divide both sides by -9
y = -4/3 + 2/3x
or
y = 2/3x - 4/3
The equation 6x – 9y = 12 written in terms of y is; y = (2/3)x - 4/3
We are required to write the equation 6x – 9y = 12 in terms of y.Rewriting the equation 6x – 9y = 12 in terms of y is as follows;
6x – 9y = 12 6x - 12 = 9yDivide through by 9 so that we have;
y = (2/3)x - 4/3

Select all of the rates that have the same constant rate of change as Michael's rate. 180 pages in 2 hours 180 pages in 2 , hours 60 pages in 30 minutes 60 pages in 30 , minutes 108 pages in 212 hours 108 pages in 21 half , hours 150 pages in 1 hour 150 pages in 1 , hour 225 pages in 150 minutes 225 pages in 150, minutes 210 pages in 2 hour 20 minutes
Answer:
180 pages in 2 hours
225 pages in 150 minutes
210 pages in 2 hours 20 minutes
Step-by-step explanation:
135 pages : 90 minutes
= 135/90
= 3/2
= 3 : 2
180 pages : 2 hours
180 pages : 120 minutes
= 180/120
= 3/2
= 3:2
60 pages : 30 minutes
= 60/30
= 2/1
= 2:1
108 pages : 2 1/2 hours
108 pages : 180 minutes
= 108/180
= 18/30
= 3/5
= 3:5
150 pages : 1 hour
150 : 60
= 150/60
= 10/6
= 5/3
= 5:3
225 pages : 150 minutes
= 225/150
= 9/6
= 3/2
= 3:2
210 pages : 2 hours 20 minutes
210 pages : 140 minutes
= 210/140
= 3/2
= 3:2

You go for a run on monday you run 2.41Km on tuesday you ran the same distance how far did you ran altogether
Answer: 4.82 km
Step-by-step explanation:
You went for a run on Monday.
You then went on a run on Tuesday as well. On this day you ran 2.41 km and it is said that you ran the same distance on both days which means you ran for 2.41 km on Monday as well.
The total distance you ran is therefore:
= 2.41 + 2.41
= 4.82 km
what is the solution to this system of equations
A. (4,2)
B. (8,4)
C. (4,8)
D. (2,4)
Answer:
B. (8,4)
Step-by-step explanation:
To find the solution of the system, look at where the lines intersect. The intersecting point is (8,4). The solution to the system of equations is (8,4).
Answer:
B. (8,4)
Step-by-step explanation:
We want to find when these two equations are equal. The long way is to actually solve them using elimination or substitution of the equations. But, we can see an easier and clever way to solve them.
There is one specific time when equations are equal and that is when their lines intersect or cross, notice the graph and where they intersect. That specific coordinate where they intersect is your answer, (8, 4)!

A jar has 2 pennies, 5 nickels, 3 dimes, and 2 quarters. What is the probability of drawing a penny,
replacing it, and drawing another penny?
There is a 2 in 12 chance of drawing a penny
Step-by-step explanation:
Answer: 2/12
Step-by-step explanation:
There are 12 coins all together, and 2 pennies which means there is a 2/12 chance to draw a penny. Then they replace the penny and draw another time, so by replacing the penny the probability doesn't change and there is still a 2/12 chance of drawing a penny.

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingTerms/CoefficientsStep-by-step explanation:
Step 1: Define Systems
3x - y = 9
2x - y = 6
Step 2: Rewrite Systems
2x - y = 6
Subtract 2x on both sides: -y = 6 - 2xDivide -1 on both sides: y = 2x - 6Step 3: Redefine Systems
3x - y = 9
y = 2x - 6
Step 4: Solve for x
Substitution
Substitute in y: 3x - (2x - 6) = 9Distribute -1: 3x - 2x + 6 = 9Combine like terms: x + 6 = 9Isolate x: x = 3Step 5: Solve for y
Define equation: 2x - y = 6Substitute in x: 2(3) - y = 6Multiply: 6 - y = 6Isolate y term: -y = 0Isolate y: y = 0Step 6: Check
Graph the systems to verify the solution set (3, 0) is the solution.
The solution set to the systems would be where the 2 lines intersect.
We see that the intersection point is x-intercept (3, 0).
∴ (3, 0) is the solution set to the systems of equations.
isolate and solve for y
Step-by-step explanation:
subtract y from both sides than divide the x values from bothe sides

YOUR ANSWER WILL BE REPORTED IF YOU PUT NONSENSE
Answer:
Here, for example, is square inch pricing, using a multiplier of 2.5 (ie, $2.50 per square inch):
4×4 inches = 16 square inches x 2.5 = $40
8×8 inches = 64 square inches x 2.5 = $160
16×16 inches = 256 square inches x 2.5 = $640
24×24 inches = 576 square inches x 2.5 = $1,440
32×32 inches = 1,024 square inches x 2.5 = $2,560
I don’t know about you, but $40 seems awfully small price for a painting by someone who commands $2,560 for a 32×32 canvas.
Here are the same canvas sizes using linear inch pricing, using a multiplier of 20 (ie, $20.00 per linear inch) — as you can see, the difference in price feels a lot less out-of whack:
4+4 inches = 8 linear inches x 20 = $160
8+8 inches = 16 linear inches x 20 = $320
16+16 inches = 32 linear inches x 20 = $640
24+24 inches = 48 linear inches x 20 = $960
32+32 inches = 64 linear inches x 20 = $1,280
Neither of these pricing methods is “right” or “wrong,” but once you determine your method and your multiplier, charging by size can be a very helpful way to eliminate the guesswork, and feel confident about your pricing.
Different Pricing for Different Media?
One possible modifier to your size-based pricing structure is the media you paint with. If you only paint watercolors, or only paint oils, there’s no problem, but if you paint both on canvas and on paper, as I do, it gets a little tricky.
For whatever reason, paintings on paper tend to sell for less than paintings on canvas — even though they require framing, which is an added expense. In my case, if I were to pay to have a piece framed, my costs become much higher for a work on paper than for a canvas painting! What’s an artist to do?
(And remember that pricing your prints is an entirely different topic.)

In the first week of July, a record 1,120 people went to the local swimming pool.In the second week, 100fewer people went to the pool than in the first week. In the third week,140 more people went to the pool than in the second week. In the fourth week, 208 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answer:
15%
Step-by-step explanation:
Given that:
Number of people who went to swimming pool in the first week = 1120
In second week, there are 100 fewer people, so
Number of people who went to swimming pool in the second week = 1020
In third week, there are 140 more people, so
Number of people who went to swimming pool in the third week = 1160
In fourth week, there are 208 fewer people, so
Number of people who went to swimming pool in the fourth week = 952
To find:
Percentage decrease in the number of people who went to the pool over the four weeks?
Solution:
Initial value = 1120
Final value = 952
Decrease in the value = Final value - Initial value
Decrease in the value = 1120 - 952 = 168
To find the percentage, we need to take the initial value in the consideration.
Therefore, percentage decrease is:
[tex]\dfrac{Decrease}{Initial\ value}\times 100[/tex]
[tex]\Rightarrow \dfrac{168}{1120}\times 100\\\Rightarrow \bold{15\%}[/tex]

PLEASE ANSWER QUICK!!! The volume of ammonia in a balloon is now 6.1 L after changing the temperature from 52 °C to 79 °C. What was the original volume?
Answer:
the original volume is 4.0L
Step-by-step explanation:
Step one:
given data
V1= ?
T1= 52 °C
V2= 6.1L
T2= 79° C
Step two
applying the volume temperature relationship, which is
V1/T1= V2/T2
substituting we have
V1/52= 6.1/79
cross multiply we have
52*6.1= V1*79
317.2= 79V1
divide both sides by 79
V1= 317.2/79
V1=4.0L
