Answer:
<u>63 km</u>
Step-by-step explanation:
<u>Given</u> :
- Speed = 315 km/h
- Time = 12 minutes
<u>Solving</u> :
<u>Convert minutes into hours so that the units are </u><u>equal</u><u>, otherwise your answer will not be correct.</u>
- There are 60 minutes in an hour
- Therefore, 12 minutes is equal to :
- 12/60 hours
- 1/5 hours
- 0.2 hours
<u>Calculating distance</u>
- Distance = Speed x Time
- Distance = 315 km/h x 0.2 h
- Distance = <u>63 km</u>

Answer:
6
Step-by-step explanation:
3=x/2
Multiply both sides by 2
Solving:
-7 + y = 3 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-7 + y + -2y = 3 + 2y + -2y
Combine like terms: y + -2y = -1y
-7 + -1y = 3 + 2y + -2y
Combine like terms: 2y + -2y = 0
-7 + -1y = 3 + 0
-7 + -1y = 3
Add '7' to each side of the equation.
-7 + 7 + -1y = 3 + 7
Combine like terms: -7 + 7 = 0
0 + -1y = 3 + 7
-1y = 3 + 7
Combine like terms: 3 + 7 = 10
-1y = 10
Divide each side by '-1'.
y = -10
Hope it helps. (:
