that’s the answe
The value of y can be calculated by translating the equation such that we solve y in terms of x.
-3x - 8y = 10
-8y = 10 + 3x
y = (10 + 3x) / -8
Then, we substitute 2 to the x in the equation.
y = (10 + 3(2)) / - 8 = 16/-8
y = -2
Thus, the value of y in the equation is -2.
Answer:
The number is -136.
Step-by-step explanation:
Let the number be x, so we have the equation:
x + 2 = 7/8 x - 15
x - 7/8 x = -15 - 2
1/8 x = -17
x = -17 * 8 = -136.
Calculating the volume of a cylinder the radius is squared,
If the radius was 8 when 8 is squared you get 64
If the radius is multiplied by 1/2 the radius would become 4, 4 squared is 16
16 / 64 = 1/4
The volume would be 1/4 the original volume, so it would be 4 times smaller.

% Change = (18 - 15) /15 * 100%
= 3/15 * 100%
= 1/5 * 100% = 20%
Percent change = 20%.
