Answer:
7 minutes
Step-by-step explanation:
The computation of the number of minutes that climbs the stairs tomorrow is shown below:
Given that
He claimed 1000 stairs in 25 minutes
So for 280 stairs, he would take
= 280 × 25 minutes ÷ 1000 minutes
= 7000 ÷ 1000
= 7 minutes
hence, 7 minutes would be taken
The same is to be considered
Answer:
-4 =x
Step-by-step explanation:
2x + 9(x – 1) = 8(2x + 2) – 5
Distribute
2x +9x -9 = 16x+16 -5
Combine like terms
11x-9 = 16x +11
Subtract 11x from each side
11x-9-11x = 16x-11x+11
-9 = 5x+11
Subtract 11 from each side
-9-11 = 5x+11-11
-20 = 5x
Divide by 5
-20/5 = 5x/5
-4 =x
Would it be LCM=24
Hope this helps :)
