Step-by-step explanation:
15 percent of what number is 12?
12 is 15% of 80
Steps to solve "12 is 15 percent of what number?"
We have, 15% × x = 12
or,
15
100
× x = 12
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 12 ×
100
15
x = 80
If you are using a calculator, simply enter 12×100÷15, which will give you the answer.

Answer:
A = Distributive Property of Multiplication
B = Addition Property of Equality
C = Subtraction Property of Equality
Step-by-step explanation:
Given:
5(2x - 1) = 9x + 2
The first step is to use the distributive property and multiply 5 to both numbers inside the brackets. So, A will be Distributive property of multiplication, which will result in:
5(2x) - 5(1) = 9x + 2
10x - 5 = 9x + 2
The next step is to add 5 on both sides of the equation. So, B will be the Addition property of equality, which will result in:
10x - 5 + 5 = 9x + 2 + 5
10x = 9x + 7
The next step is to subtract 9x from both sides of the equation. So, C will be the Subtraction property of Equality, which will result in:
10x - 9x = 9x + 7 - 9x
x = 7
The value of x in the diagram is 15° and the value of y is 6°

The figure given is a triangle. A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees
The first step is to determine the value of x.
The value of x can be determined using the exterior angle.
The sum of the two interior opposite angles in a triangle is equal to the external angle
(4x - 7)° + 86° = (9x + 4)°
Combine similar terms
9x - 4x = 86 - 7 - 4
5x = 75
x = 15°
To determine the value of y, first substitute for the value of x in the angle (4x - 7)°
(4x - 7)° = (4x15) - 7 = 53°
The sum of angles in a triangle add up to 180°
53° + 86 + (7y - 1) = 180°
add like terms
138 + 7y = 180
7y = 42
y = 6°
