ABC = 35
Step-by-step explanation:
x and 3x-70 are corresponding angle and corresponding angle are equal when the lines are parallel
x = 3x-70
Subtract 3x from each side
x-3x = 3x-70-3x
-2x= -70
Divide by -2
-2x/-2 = -70/-2
x = 35
x = 3x-70 = 35

Answer:
The ratio between two values A and B is just the quotient between these two values:
ratio = A/B
a) $280 in 7m
Here the ratio is:
$280/7m = $40/m
This also can be read as:
$40 per meter.
b) 105 miles in 2 hours
Here the ratio is:
105mi/2h = 52.5 mi/h
This also can be read as:
52.5 miles per hour
c) $33 for 5lb
The ratio is:
$33/5lb = $6.6/lb
This can be read as:
$6.6 per pound.
d) 50 pages in 2 hours
the ratio is:
(50 pages)/2h = 25 pages/h
this can be read as:
25 pages per hour.
