Answer:
B.15
Step-by-step explanation:
To get from 4 to 12, you multiply by 3. You do the same to 5 to get the missing number. 5x3=15
12:30
A to B
30 + 12 is 42
so... the final answer would be 12:30.
In each of the problems, one of the equations is solved for y. Just plug in what y is equal to into the other equation.
1.) Plug -3 in for y.
-3 = 7x - 10
7x = 7
x = 1
2.) Plug -8 in for y.
-8 = -2x - 12
-2x = 4
x = -2
9.) Plug -8x in for y.
2x + 4(-8x) = 0
2x - 32x = 0
-30x = 0
x = 0
10.) Plug 2x in for y.
6x + 7(2x) = 20
6x + 14x = 20
20x = 20
x = 1
Answer: Option (4)
Step-by-step explanation:
The y-intercept of the line is (0, -1). This eliminates everything except for option (4).
Answer:
6 miles
Step-by-step explanation:
60 miles : 5 inches
12 miles : 1 inch
6 miles : 1/2 inch
whatever you do to one side of the ratio you have to do to the other.
to get from 1 to a 1/2 you divide by 2, so you do 12 divided by 2 which is 6.
