Answer:
k = -8
Step-by-step explanation:
-2k+13=-8k-35
Add 8k to each side
-2k+8k+13=-8k+8k-35
6k +13 = -35
Subtract 13 from each side
6k+13-13 = -35-13
6k = -48
Divide by 6
6k/6 = -48/6
k = -8
Given:
18 points on her quiz
24 points is equivalent to 100%
18 is to 24 or 18/24
x is to 100% or x/100%
18/24 = x/100%
18 * 100% = 24x
1800% = 24x
1800%/24 = x
75% = x
18/24 = 75%/100%
18 * 100% = 24 * 75%
1800% = 1800%
