Answer:
A 19 inch tv cost $89
Step-by-step explanation:
37 inch tv : 400 = 5x - 45
19 inch tv : x
We have the equation:
5x - 45 = 400
5x = 445
x = 89
We know how many miles he drove and the speed that he drove. We do not know how long i took him to drive that distance.
To find the time it took, divide the distance by his speed:
325 miles / 65mph = 5 hours.

Answer:
4th option
Step-by-step explanation:
The relationship is linear,
putting the value of x in the right side of the equation of option 4, you'll get the value of the left side
putting, x=1
y+4=-1/2(x-1)
y=-1/2(1-1)-4
y=-4
putting, x=7
y+4=-1/2(7-1)
y=-1/2(6)-4
y=-6/2-4
y=-3-4
y=-7
the height is 11.25 because 7×4=28×11.25=315
