Answer:
Hello,
Step-by-step explanation:
We divide the interval [a b] in n equal parts.



Chrissy's score = c
Twice means multiply by 2
twice Chrissy score = 2c
the sum of 22 and twice Chrissy score: 22+2c
4x - 57 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540
16x - 20 = 540
16x = 560
x = 35
hope this helped
You can do all strategies. Multiplication, Division, Addition, and Subtraction are the strategies because you can multiply 7 by 4 to get 28, divide 56 by 2 to get 28, add 14 by 14 to get 28, or subtract 40 by 12 to get 28.
