Answer:
y=6
Step-by-step explanation:
y= -3/2(-4) : y=4
y=-2 3/4(-4)
y=3/2. 4
y= 3×4/2

Step-by-step explanation:
In this question, you have to simplify the expression.
Solve:
2(x + 4) + 3(x - 4)
Use the distributive property.
2x + 8 + 3(x - 4)
2x + 8 + 3x - 12
Combine like terms.
5x + 8 - 12
5x - 4
Since there is no more similar terms, we are left with our final answer.

1. It costs $3.45 to buy 3/4 lb of chopped walnuts. How much would it cost to purchase
7.5 lbs of walnuts? Explain or show your reasoning.
Answers
Answer:
$34.50
Step-by-step explanation:
First, how many 3/4 lbs are in 7.5 lbs?
7.5 lbs = 15/2 lbs.
(15/2) / (3/4) = 10
There are 10 "3/4" lbs in 7.5 lbs.
So, if it costs $3.45 to purchase 3/4 lbs of chopped walnuts, it would cost $3.45 times 10 dollars to purchase 7.5 lbs of chopped walnuts, or $34.50.

Three rectangles next to each other with a width of 8 feet. The first and second rectangles length are unknown, and the last is 13 feet long. There are two right triangles above and below the last rectangle. One is labeled with a base of 5 feet and a height of 12 feet.
88 square feet
232 square feet
283 square feet
300 square feet
Answers
Answer: The answer is 300
Step-by-step explanation: The triangle formula = ( B · H) ÷ 2
B = 5 H = 12 5 · 12 = 60 ÷ 2 = 30
Since there is two triangles you will have two 30's.
The rectangle farthest to the right = 13 · 8 = 104
If you unfold the triangle it will line up perfectly with the 3 rectangles, so...
The middle rectangle = 5 · 8 = 40
The rectangle farthest to the right = 12×8 = 96
Add them all up
30 + 30 + 104 + 40 + 96 = 300

Answer:
∠W = 130∠X = 140∠Y = 50∠Z = 40Step-by-step explanation:
Using 'y' and 'z' to represent angles with the corresponding names, we have ...
y + z = 90
(3b -1) +(2b +6) = 90 . . . . substitute the given expressions
5b +5 = 90 . . . . . . . . . . . . simplify
b +1 = 18 . . . . . . . . . divide by 5
b = 17 . . . . . . . . subtract 1
Then the angles are ...
y = 3b -1 = 3(17) -1 = 51 -1 = 50
z = 2b +6 = 2(17) +6 = 34 +6 = 40 . . . . note that these are complementary, as theys should be
Angles W and Y form a linear pair, so are supplementary:
W = 180 -Y = 180 -50 = 130
Angles X and Z form a linear pair, so are supplementary:
X = 180 -Z = 180 -40 = 140
Then the angle measures are ...
∠W = 130∠X = 140∠Y = 50∠Z = 40Thorton's department store has a 30% off sale this week what is the sale price for a pair of $24 jeans

What do opposite rays form

Here is ray AB
A B

It starts at point A, goes through point B, and goes only in one direction, to the right. Points A and B lie on line AB.
Now I'll add an opposite ray whose endpoint is also point A.

Ray AC also lies on the same line as ray AB, but starting at point A, it goes in the opposite direction of ray AB. When you add ray AC to its opposite ray AB, you get the entire line AB.
