Answer:
He climbed 19 steps
Step-by-step explanation:
Let steps climbed in 9.5 seconds = z
If 24 steps = 12 seconds
then: z = 9.5 seconds
Using criss cross method
24 x 9.5 = 12 x z
228 = 12 z
z = 228/12
z = 19 steps

Answer:
w = -20
Step-by-step explanation:
-
+ 9 = 13
Shift the (+9) to the other side of the equation. (+9) will turn into (-9).
-
= 13 - 9
= 4
Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).
-w = 4 × 5
= 20
Multiply both sides of the equation by (-1) so that -w will turn into w.
w = (-1) × 20
w = -20
