Acar traveled 175 mi at a certain speed. if the
speed had been 20 mph faster, the trip could have
been made in 1 hr less time. find the speed.

The car speed: 50 mph

Step-by-step explanation:

The car speed supposed to be x mph

The time spend is y hour

Xy = 175

(x + 20) * (y – 1) = 175

Xy – x + 20y -20 = 175

Xy = x – 20y + 195

175 = x – 20y + 195

X – 20y = 175 – 195 =- 20

X =  20y - 20

(20y - 20) * y = 175

20y2  - 20y -175 = 0

(2y + 5) * (10y - 35) = 0

Y = 3.5  ( answer)  or y = - 2.5 (not answer, because time can’t be negative)

X = 175/3.5 = 50 mph

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
