Answer:
y=4
x= 3/7
Step-by-step explanation:
2y=8
Divide both sides by 2
2y÷2=8÷2
A.) y=4
Substitute 4 for y
7x−2y=−5
7x+(−2)(4)=−5
Simplify both sides of the equation.
7x−8=−5
Add 8 to both sides
7x−8+8=−5+8
7x=3
Divide both sides by 7
7x÷7= 3÷7
x= <u>3</u>

Answer:
Mass determines how fast a car can accelerate. Since a car accelerates slower with more adults, and faster with less adults, this means that the mass has a big impact on acceleration. Therefore, we can conclude that the mass determines how fast a car can accelerate.
Well the exact form is 1/3138428376721
and in decimal form it's 3.18630817 • 10 ^-13
see the attached figure to better understand the problem
Let
x------> the length side of a rectangle
y-------> the width side of a rectangle
we know that
the perimeter of a rectangle is equal to the formula
In this problem
Step 1
<u>Find the distance AB</u>
we know that
the distance's formula between two points is equal to
substitute the values
Step 2
<u>Find the distance BC</u>
we know that
the distance's formula between two points is equal to
substitute the values
Step 3
<u>Find the perimeter</u>
we know that
the perimeter of a rectangle is equal to the formula
substitute the values of the distance in the formula
therefore
<u>the answer is</u>
The perimeter of the rectangle is equal to
