Answer:
x = 12
Step-by-step explanation:
We know that the total angle measure of a triangle is 180 degrees, so the sum of all the angles should be 180 degrees.
Therefore, we can add all the angles, set them equal to 180 and solve for x
2x+5 + 6x-5 + 7x = 180
We can combine all the x terms and all the numerical terms on the left side of the equation to get:
(2x+6x+7x) + (5-5) = 180
15x = 180
Then we can divide both sides by 15 to isiolate x
15x = 180
x = 180/15 = 12
Answer:
A
Step-by-step explanation:
2^2 and 3^2 = 4 + 9 = 13
71 inches X 36 inches = 2556 sq inches
convert sq.feet to sq.inches.
12 sq. feet = 1 sq. inch
2556 sq. feet × 1 sq. inch ÷ 12 sq. feet = 213 sq. inches (sq. feet ÷ sq. feet cancels out the feet variable leaving sq. inch)
Answer:
11/12
Step-by-step explanation:
1/2 = .5
11/12=.91666667
.5 < .91666667
Let x be total amount traveled Therefore, x(.8333) = 90 x = 108 108 miles
