1) x + 4 = 3
2) x + 7 = -3
3) x + 9 = 14

1) x + 4 = 3

x = 3-4

x = -1

2) x = -3-7

x = -11

3) x = 14-9

x = 5

1) X +4 = 3

X = -1

2) X+7 = -3

X = -10

3) X +9 = 14

X = 5

hope this helps , i am bad at explaining

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

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.
