The correct answer is x= -6 let me know if you want to know how I got that or if you needed to know if it is no solution/ infinite/etc..
Answer:
<h2>x = -18</h2>
Step-by-step explanation:
<u>2x</u> - 1 = <u>3x</u> + <u> 1 </u>
3 4 2
<u>2x</u> - <u>3x</u> = 1 + <u> 1 </u>
3 4 2
_ <u> 1x </u> = 1.5
12
-1x = 12 (1.5)
x = 18 / -1
x = -18
<u>proof: </u>
<u>2(-18)</u> - 1 = <u>3(-18)</u> + <u> 1 </u>
3 4 2
-12 - 1 = -13.5 + 0.5
-13 = -13 --ok

It takes the faster pump 12 minutes to fill the tank. Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.
Answer:
distance in 3 hours = 150 miles
distance in 1 hour = 150/3 = 50 miles
distance in 9 hours = 50 × 9 = 450 miles
Substitution:
u = - π x
d u = - π d x
d x = - d u / π
