Question

TIME REMAINING 59:36 Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go. If Yan made 8 stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan climbed

Answer 1

Options :

4+4+4+4

8+8+8+8

(-1)(4+4+4+4)

(-8) + (-8) + (-8) + (-8)

Answer:

-8 + - 8 + - 8 + - 8

Step-by-step explanation:

Given that:

Rungs of ladder moved per stop = 4

Number of stops made = 8

Number of ladder rungs :

Ladder rungs per stop * number of stops

- 4(descent) * 8= - 32 ladder rungs

Alternative way :

-8 in 4 places

-8 + - 8 + - 8 + - 8 = - 32
