The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t. Which is an equivalent equation solved for a?
O f-v=a
OI-v=a
Of+V = a
o {+v=a

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
