Answer:
y = 5
Step-by-step explanation:
7(y + 2) – (4y – 10) = 44 – 2y + 5
(7y+14) - (4y - 10) = 49 -2y
3y +24 = 49 -2y
5y +24 = 49
5y = 25
y = 5
Answer:
y=5
Step-by-step explanation:
7(y+2)-(4y-10) = 44-2y+5 distribute on the left and combine like terms on the right side of the equation
7y + 14 -4y +10 = 49 - 2y move every term with a variable on the left side with a change sign and the numbers on the right side
7y-4y+2y =49 -14 -10
5y = 25 divide both sides by 5
y5/5=25/5 so
y=5

Step-by-step explanation:
Compare the perimeter and area of the original figure to the enlarged figure using proportions.
A small rectangle has a length of 2, and a width of 1. A large rectangle has a variable length of b, and width of 2. StartFraction enlarged side (2) over Original side (1) = StartFraction Enlarged perimeter (4 + 2 b) over Original perimeter (6) EndFraction. (StartFraction enlarged side (2) over Original side (1) EndFraction) squared = StartFraction Enlarged area (2 b) over Original area (2) EndFraction
Which statements describe true relationships? Check all that apply.
The enlarged area is 4 times the original area, which is the square of the scale factor.
The scale factor is One-half.
The enlarged perimeter is 2 times the original perimeter, which is the scale factor.
The perimeter is proportional to the scale factor and the area is proportional to the square of the scale factor.
The enlarged area and perimeter are equal.

Barry simplified 5x – 3y – x + 6z, as shown.
5x – 3y – x + 6z
5x – x – 3y + 6z
5 + 3yz
Describe two mistakes Barry made, and find the correct solution.
__________________________________________________
Answer:
Step-by-step explanation:
we have that
5x – 3y – x + 6z
5x – x – 3y + 6z------> this step is correct
5 + 3yz------> is not correct
because
1) 5x-x=5---> is not correct
the correct is
5x-x=4x
2) -3y+6z=3yz-----> is not correct
the correct is
-3y+6z=3*(2z-y)
therefore ,
the correct solution is
4x+3*(2z-y)

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.
Answer:
Step-by-step explanation:
Given
There are 9 people going on a trip
They purchased coach tickets =$160
first class tickets =$1180
total budget to spend = $4500
Let coach tickets=X
So first class tickets=9-x
160x+1180(9-x)=4500
160+10620-1180x=4500
160x-1180x=4500-10620
-1020x=-6120
X=6120/1020
X=6
So answer
Coach tickets=X=6
First class tickets=(9-x)
=3.

Answer:
x + 2x = 108
Step-by-step explanation:
Let x be the number of oranges sold on Thursday
The number of oranges sold on Friday is twice as many or 2 times x, 2x
The total sold on the two days is 108. Add the number sold on Thursday and Friday together and let it equal to 108
x + 2x = 108
