Answer:
3x-5y=-15
Step-by-step explanation:
For question 22, divide each number by 1.41 to see which one produces a quotient larger than 0.9. d is the answer.
For #23, multiple 0.155 million by 86%, the result is 133,300
again, d is the correct answer.
You didn’t add a screenshot. I’m sorry for answering but someone else will if I don’t.
Find the unit rate which is 260/12 which is 21 and 2/3 now divide 286 by 21 and 2/3.
Let the weight of the first truck be represented by w.
total weight = w + (2 + w) + (2 + 2 + w) + (2 + 2 + 2 + w)
32 = 4w + 12
20 = 4w
w = 5
Therefore, the first truck weighs 5 tons, the second weighs 7 tons, the third weighs 9 tons and the fourth weighs 11 tons.
