Answer:
Julio's number is 40
Step-by-step explanation:
"If you subtract 17 from my number and multiply the difference by negative 4, the result is negative 92.
n= number
(n-17)*(-4) = -92
distribute
-4 *n - 17*(-4) = -92
-4n +68 = -92
subtract 68 from each side
-4n +68-68 = -92 -68
-4n = -160
divide each side by -4
-4n/-4 = -160/-4
n = 40
Answer:
x = 23
Step-by-step explanation:
∠ ABE = ∠ BEF = 4x ( alternate angles )
Since DBF is a straight line then the 3 angles sum to 180°, that is
x + 4x + 65 = 180
5x + 65 = 180 ( subtract 65 from both sides )
5x = 115 ( divide both sides by 5 )
x = 23
