Solve for x:/X - 2+ 10 = 12 (1 point) x= 0 and x = 4
x= -4 and x = 0
x= -20 and x = 4
No solution

x=4

Step-by-step explanation:

Rewrite as

x-2+10=12

x=12+2-10

x=4

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

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.
