What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?
Answer:
open the brackets of two sides
ie; 1.5x+6-3=4.5x-9
1.5x+3=4.5x-9
4.5x-1.5x=3+9
3x=12
X=4

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack of pencils.
Which equation shows an equality between two different ways of expressing the cost for all the pencils?
A. 8 = 4p
B. 8 = 4/p
C. 8 = 4 + p
D. 8 = 4 – p
==================================================
Explanation:
p is a placeholder for a number. Think of it like a box where a number goes inside.
In this case, p is the price of one pack of pencils.
We can use a proportion to help set up an equation
(4 packs)/(8 dollars) = (1 pack)/(p dollars)
4p = 8*1 ... cross multiply
4p = 8
8 = 4p which points to choice A as the answer.
---------------------------
Alternative method:
4 packs = 8 dollars
1 pack = p dollars
Multiply both sides of the second equation by 4 and you'll get
4 packs = 4p dollars
Then replace the "4 packs" on the left hand side with "8 dollars"
8 dollars = 4p dollars
that turns into
8 = 4p
--------------------------
Yet another method:
We know it's $8 for 4 packs. This must mean it is 8/4 = 2 dollars per pack.
If p is the cost of one pack, then p = 2.
Now plug p = 2 into each of the four answer choices. You should find that only 8 = 4p results in a true equation.
Choice B is false because 8 = 4/p turns into 8 = 4/2 and that becomes 8 = 2, which is a false equation. Choices C and D are similar stories.
Answer:
The answer is A

hector and alex traded video games. alex gave hector one fourth of his video games in exchange for 6 video games. then he sold 3 video games and gave 2 video games to gis brother. alex enbed up with 16 video games. how many video games did alex have when he started?
Answer:
20 games
Step-by-step explanation:
Lets work backwards; *Adding what he gave away or lost*
-Alex started with 16 video games
-Add the games gave to his brother (+2)
-Add the games he sold (+3)
-The number is 3/4 of his games
-Subtract the games he traded with hector (-1/4)
Equation: 16+2+3-6= 3/4 X (variable) *You can choose other than X*
21-6 = 15
15 = 3/4
Take the reciprical of 3/4 which is 4/3 and multiply it by both sides
4/3 x 15 = 3/4 x 4/3
4/3 X 15 = 20!
ALEX STARTED WITH 20 GAMES!

Use the distance formula to find the distance, to the nearest tenth, from S(5,-4) to W(-3,7)
Answer:
Distance (d) =13.6
Step-by-step explanation:

At Grocery Mart, strawberries cost $2.99 for 2 lb., and at Baldwin Hills Market strawberries are $3.99 for 3 lb.
What is the unit price of strawberries at each grocery store? If necessary, round to the nearest penny.
Grocery Mart:
$_________
Answer:
Unit Price at Grocery Mart = $1.50
Unit Price at Baldwin Hills = $1.33
Step-by-step explanation:
Unit price in this case will be the price divided by number of pounds
Let u1 be the unit price of Grocery Mart and u2 be the unit price at Baldwin Hills
Given
[tex]s_1 = 2.99\\w_1 = 2\\s_2 = 3.99\\w_2 = 3[/tex]
The unit price for Grocery Mart is:
[tex]u_1 = \frac{s_1}{w_1}\\= \frac{2.99}{2}\\= 1.495[/tex]
Rounding off to nearest penny
u1 = $1.50 per lbs
Unit price for Baldwin Hills is:
[tex]u_2 = \frac{s_2}{w_2}\\=\frac{3.99}{3}\\=1.33[/tex]
u2 = $1.33 per lbs
Hence,
Unit Price at Grocery Mart = $1.50
Unit Price at Baldwin Hills = $1.33

Given that you have 2 parallel lines cut by a transversal, what is the measure of angle 2?
Step-by-step explanation:
angle 2 = 2x + 10 deg (corresponding angles) or 180 - 4x + 46 deg (angles on a straight line are supplementary)
therefore,
2x + 10 = 226 - 4x
6x = 216
x = 36
hence,
angle 2 = 2(36) + 10 = 82deg

The table below shows the coordinates of a figure that was transformed.

Which is the correct description of the transformation?

b
Reflection over the x-axis
c
Translation 5 units left and 2 units down
d
Translation 10 units left and 4 units down
Answer: You're answer to you question would be D
Step-by-step explanation:
The correct description of the transformation translation 10 units left and 4 units down. The correct option is D.
What is transformation?The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given the per-image and image of different points. Now, if we look at the coordinates of the A and A', then it can be observed that if 10 units is deducted from the x-coordinate of A, then the x-coordinate of A' will be the result.
Similarly, if 4 units is deducted from the y-coordinate of A, then the y-coordinate of A' will be the result.
Further, it is known that reducing n units from x-coordinate means that the point is shifted left by n units. Also, if p units are deducted form the y-coordinate then the point is shifted p units down.
Hence, the correct description of the transformation translation 10 units left and 4 units down.

Harry buys a TV priced at £1200 plus 20% VAT. He pays £300 deposit and the balance in ten equal monthly payments. Calculate each monthly payment. please explain fully in parts.
Answer:
114 monthly payment
Step-by-step explanation:
1200 + 20%= 1440 (20% of 1200 equals 240)
the VAT has to be added to the purchase price.
1440 is the total price he had to pay for the tv.
he pays 300 down. 1440-300 = 1140
1140 is the remaining balance he had to pay over the next 10 month.
1140 ÷ 10 = 114
divide 1140 by 10 payments and you receive you monthly payment amount. 114

If C=24, what values of A and B complete Ax+By=C for each graph? Write the standard form for each equation.
For the graph in part a, the value for A is =
and the value for B is =
Answer:
Step-by-step explanation:
For graph (a),
Let the equation of the line is,
Ax + By = C
For the line passing through (4, 0) and C = 24,
4A + B(0) = 24
4A = 24
A = 6
For a point (0, -3) lying on this line,
A(0) + B(-3) = 24
-3B = 24
B = -8
Therefore, equation of the line will be,
6A - 8B = 24
3A - 4B = 12
b). If the equation of the given line is,
Ax + By = 24
For a point (3, 0) lying on the line,
3A + B(0) = 24
A = 8
For a point (0, 2) lying on the line,
A(0) + 2B = 24
2B = 24
B = 12
Therefore, equation of the given line will be,
8A + 12B = 24
2A + 3B = 6

What is the cost of each item? What is the subtotal? What is the tax? What is the total paid? Shoes: $49.99 (normally) they are on sale for 25% off Jacket: $137.99 (normally) it is on sale for 33% off Pack of Cookies: $4.49 7.3% Sales Tax What is the cost of each item? What is the subtotal? What is the tax? What is the total paid?
Answer:
Cost of shoes = $37.4925
Cost of jacket = $92.4533
Tax = $9.81
Total paid = $144.2458
Step-by-step explanation:
Normal price of shoes = $49.99
Discount = 25%
Discounted price:
[tex]\$49.99 - \$49.99\times \dfrac{25}{100} = \$37.4925[/tex]
Normal price of jacket = $137.99
Discount = 33%
Discounted price:
[tex]\$137.99 - \$137.99\times \dfrac{33}{100} = \$92.4533[/tex]
Price of pack of cookies = $4.49
No discount on cookies as per question statement.
Total amount without tax = $37.4925 + $92.4533 + $4.49 = $134.4358
Sales Tax = 7.3% of total amount without tax = 7.3% [tex]\times[/tex] $134.4358 = $9.81
Total paid = $134.4358 + $9.81 = $144.2458
