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>

Hey there! :)
The formula for finding volume of a sphere = 4/3 · π · r³
Radius = 1
1³ = 1 × 1 × 1 = 1
π = 3
3 × 1 = 3
3 × 4/3 = 12/3 = 4
The volume is 4 in³
Hope this helps :)
Answer:
the triangle
Step-by-step explanation:
The perimeter is the sum of the all sides of the shape.
Triangle:
3√147+2√108+2√48+3√75+ 6√12
147=49•3, 108=36•3, 48=16•3, 75=25•3, 12=4•3 that means
√147=7√3, √108=6√3, √48=4√3, √75=5√3, √12=2√3
perimeter=3•7√3+2•6√3+2•4 √3+3•5√3+6•2√3=68√3
Square:
4•1/3•√63=4/3•√9•√7=4√7
Rectangle:
2•1/4√100+2(2√48+4√75)=
5+2(8√3+20√3)=5+56√3
Now, if you use a calculator, you will find that the greatest perimeter is for the triangle shape.
