If I did this correctly it simplifies to 0 = 8. So I think B is the correct answer. Hope this helps!!
Answer:
42=7(z-3)
We simplify the equation to the form, which is simple to understand
42=7(z-3)
Reorder the terms in parentheses
42=+(+7z-21)
Remove unnecessary parentheses
+42=+7z-21
We move all terms containing z to the left and all other terms to the right.
-7z=-21-42
We simplify left and right side of the equation.
-7z=-63
We divide both sides of the equation by -07 to get z.
z=9

Answer:
X= 143°
Step-by-step explanation:
You could do it your way or as you can see, there's a right angle, which equals 90°, so you could either add 44+46+53 or 90+53. You get the same answer, which is 143°.
Answer: 349.6 gallons
Step-by-step explanation:
This is a simple proportion problems.
The flow rate = 87 . 4 gallons was dispensed in 15 minutes
That is 15 minutes = 87.4 gallons
Therefore 1 minute = ( 87.4/15 ) gallons
Recall 60 minutes = 1 hour
Now in 60 minute = (87.4/15 ×60/1 ) gallons
= 87.4 × 4
= 349.6 gallons
(Invariably) , Alternative method
15 minutes. = 1/4 of an hour 1/4 = 87 .4 gallons. A gallon. = 87.4/1/4
Recall that reciprocal of 1/4 = 4
Now = 87 .4/1/4
=87.4 × 4
Therefore 1 hour = 87.4 × 4 × 1
= 349 . 6 gallons
