JK+KL=JL
(5x-8)+7x-12=10x-2
(add common terms together)
12x-20=10x-2
(get the term with x alone on one side of the equation)
2x=18
(divide by 2 to get x alone)
x=9
Find KL:
KL=7(9)-12
KL=51
Answer: 84%
Step-by-step explanation:
1. You know that the student earned 42 out of 50 points on the last test.
2. Then, to calculate the percent the student earned, you must divide 42 points by 50 points and then you must multiply by 100, as you can see below:
Let's call the percent the student earned. Then:
%
10.48 divided by 1.13 = 8
1.404 divided by 0.45 = 3.12
3+2 = 5
80/5 =16
16 x 3 = 48
16 x 2 = 32
Answer= 48:32
I think this is right
