2(x+7)+3(x+1)
= 2x+14+3x+3
= 5x+17
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>q is independent variable, we need to solve it for s:</u>
- 6q = 3s - 9
- 3s = 6q + 9
- s = 2q + 3
<u>Correct choice is </u>
Answer:
option A
a = 8.65 m/s²
Step-by-step explanation:
Given that,
force applied on a cart (forward direction) = 19N
frictional force experience by cart (backward direction) = 1.7N
mass of the cart = 2 kg
Frictional force always opposes applied force, so the Resultant force on the cart would have to be 19N - 1.7N.
Formula to use
Resultant force = ma
plug values in the formula
19 - 1.7 = 2(a)
17.3 = 2(a)
a = 8.65 m/s²
so the acceleration of the cart is 8.65m/s²
Answer:
B) 5 hours
Step-by-step explanation:
First, find the amount of mph between 60 and 80:
80 - 60
= 20 mph
Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:
20/4
= 5
So, the correct answer is B, 5 hours
