Answer:
x=26
Step-by-step explanation:
The sum of all angles in a triangle is equal to 180
x + 55 + (4x-5) = 180
Combine like terms
5x +50 = 180
Subtract 50 from each side
5x +50-50 = 180-50
5x = 130
Divide each side by 5
5x/5 =130/5
x =26
A foot is 12 inches.
3 inches divided by 12 inches = 3/12 or 1/4 of a foot.
Answer:
-3
Step-by-step explanation:
the coefficient of the x term is the slope in any equation that is in slope intercept form
(2x+3)-6 = 11
2x + 3 - 6 = 11
2x - 3 = 11
2x = 11+3
2x = 14
x = 7
