A gear rotates 8 times every 15 seconds. Based on the information, which of the following could NOT be true? a: the gear rotates 48 times in 90 seconds.
b: the gear rotates 32 times in 1 minute.
c: the gear rotates 16 times in 30 seconds.
d: the gear rotates 24 times in 60 seconds

y/x=18

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer is 33
