Answer:
8
Step-by-step explanation:
Use substitution: substitute each number from the set in for x, and see if the result from dividing is 45.
4
360/x=45
360/4=90
90 ≠ 45
Therefore, 4 does not make the equation true
8
360/x=45
360/8=45
45=45
Therefore, 8 does make the equation true.
16
360/x=45
360/16=22.5
22.5 ≠ 45
Therefore, 16 does not make the equation true.
So, 8 is the value that makes the equation true
Answer:
4x-111
Step-by-step explanation:
let 'my number' be 'x'
x-15 -> (subtract from x)
4(x-15) -> (multiply result from (x-15) by 4)
4(x-15) - 51 -> (subtract 51 from result from [4(x-15)])
4x-60-51
4x-111
This is the expression for the number
