Answer:
x = 11
Step-by-step explanation:
Slope(m) is given by:
m = change in y ÷ change in x
3/4 = (4 - 1) ÷ (x - 7)
= 
Cross multiplying gives:
3x - 21 = 12
3x = 33 , x = 33/3 = 11
The answer is E.90
1/2 inches = 10 miles
9(1/2) inches = 4 1/2 inches
9(10) miles = 90 miles
115°
A triangle is 180° so add the two degrees given and subtract that from 180; 180-(75+40)
180-155= 65. then a line is 180 degrees so you subtract 65 from 180 and get 115
