X/8 = 9/5

5x = 72

x = 72/5

x = 14.4



18/y = 9/5

90 = 9y

9y = 90

y = 90/9

y = 10



34/z = 9/5

170 = 9z

9z = 170

z = 170/9

z = 18.8° (nearest tenth)

If 7x + 4 = -19 + 5x, then 2x – 14 equals<br>A-23<br>B 23<br>C-37<br>D-14​
drek231 [11]

Answer:

C

Step-by-step explanation:

Here we have the question,

7x+4 = -19 + 5x

Now we add 19 to both sides,

7x + 4 + 19 = -19 + 19 + 5x

7x + 23 = 5x

Now we subtract 7x from both sides,

23 = -2x

We divide -2 from both sides,

x = -23/2

Now we plug this in into 2x - 14,

2(-23/2) - 14 = -23-14 = -37

Our answer is C
