Can anyone me with this problem? ?

9.

Step-by-step explanation:

So basically, we need to find out x. So we know that ZX = YW because ZY and XY are already congruent and it's just adding a three to the value because of YX. We can find out x.

ZX = YW

5x + 17 = 10 - 2x

x = -1

Then we can find out the value of ZX and YW by plugging in x.

5(-1) + 17 = ZX = YW = 12.

Then we see that YX is 3 so...

ZX = ZY + YX

12 = ZY + 3

ZY = 9

So the answer is 9.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
