N - the number
8/100 × n = 0.08 × n = 0.08n
You would form this inequality:
52 + 2x < (or equal to) 180
Then, solve as you would in an ordinary equation.
Subtract 52 from both sides of the sign. 180 - 52 = 128.
So, 2x is less than or equal to 128.
Divide 128 into two to get 64.
The height of the frame must be 64 inches.
Answer:
x = 11
Step-by-step explanation:
Given
9x - 43 = 5x + 1 ( subtract 5x from both sides )
4x - 43 = 1 ( add 43 to both sides )
4x = 44 ( divide both sides by 4 )
x = 11
