Answer:
4b - a = 15
Step-by-step explanation:
if you replace the variables with their equivalent counterparts you get the equation 4(7) - 12 = __ when you do the math make sure to do the parentheses first then subtract, just like in elementary school remember pemdas parentheses, exponents, multiplication, division, addition, subtraction. I hope this helps.
good luck:)
Brainliestttt Plssssssss:)
Y = 5x + 2
3x = y + 10
3x = y + 10
3x = 5x + 2 + 10
3x = 5x + 12
3x - 5x = 12
-2x = 12
x = -6
substitute x = -6 into y = 5x + 2
y = 5(-6) + 2
y = -30 + 2
y = -28
x = -6, y = -28
hope this helped, God bless!

Answer:
15
Step-by-step explanation:
5 - 3[ 2 + (-5)] 2 - 8
Subtract 5 from 2 to get −3.
5 - 3 (-3) × 2 - 8
Multiply 3 and −3 to get −9.
5 - (-9 × 2) - 8
Multiply −9 and 2 to get −18.
5 - (-18) - 8
The opposite of −18 is 18.
5 + 18 - 8
Add 5 and 18 to get 23.
23 - 8
Subtract 8 from 23 to get 15.
15

Answer:
804 in^2
Step-by-step explanation:
The surface area of a sphere is given by A = 4πr^2, where r is the radius of the sphere.
Here, A = 4π*8^2 in^2 (must use units of measurement)
=256π in^2, or approximately 804 in^2
