Answer:
3
Step-by-step explanation:
21x + 6 = 3x + 60 subtract 3x from both sides
(21x-3x) + 6 = 60
18x + 6 = 60 subtract 6 from both sides
18x= 60-6
18x= 54 divide by 18
x =3
Question:
Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
Step-by-step explanation:
Given
<em></em><em> --- It is negative because he is climbing down</em>
Required
An expression for the number of rungs climbed
To do this, we simply multiply the number of rungs by the steps taken.
This can be rewritten as:
The product, when written as sum is:
we know that
The Cosecant is a trigonometric function that is the reciprocal of the sine
