Solve the equations below. 2t+4=7+5(t-4) b. 54w-2=8+2w-6+12

t=8  w=4/13

Step-by-step explanation:

a 2t+4=5t-20

3t=24

t=8

b

52w=16

w=16/52

w= 4/13

1.5%

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
