Answer:
k = -5
Step-by-step explanation:
The variable is k
9k + 1 = -9 + 7k
-7k -1
2k = -10
2k/2 -10/2
k = -5

We have to find the unit rate, so we have to divide what you earned in interest by the amount of months.
120/8=15
So you earn $15 per month

sorry if this doesn't help
Let's call the weight of an ostrich o=180.
we know that o=20+4*k, or, if we substitute o for 180: 180=20+4*k
where k is the weight of a kiwi.
if we want to know k, we have to subtract 20 from both sides of the equation first:
160=4*k
and divide them by 4:
40=k
So a kiwi is 40 inches high.

Answer: 640c - 6.25s - 8.75g</h3>
===============================================
Work Shown:
s = number of small cups
g = number of large cups
c = number of coolers
----------
1 cooler = 640 fluid ounces
c coolers = 640c fluid ounces
1 small cup = 6.25 fluid ounces
s small cups = 6.25s fluid ounces
1 large cup = 8.75 fluid ounces
g large cups = 8.75g fluid ounces
----------
T = total amount of water poured
T = (amount from small cups) + (amount from large cups)
T = 6.25s+8.75g
L = amount of water left
L = (original total amount of water) - (amount of water poured out)
L = 640c - T
L = 640c - (6.25s+8.75g)
L = 640c - 6.25s - 8.75g
