Answer:
Step-by-step explanation:
Simplifying
7x + 2y = 180
Solving
7x + 2y = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = 180 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = 180 + -2y
7x = 180 + -2y
Divide each side by '7'.
x = 25.71428571 + -0.2857142857y
Simplifying
x = 25.71428571 + -0.2857142857y
Answer:
angle 1 = 105º
angle 2 = 75º
Step-by-step explanation:
angle 2 = 75º
corresponding angle to the 75º angle
angle 1 = 105º
it's supplementary to angle 2
180 - 75 = 105
8 rotations. first must convert 50 ft into inches. 50x12=600 in. If you know the distance and the length of rotation, divide the length (600) by the length of each rotation (75) and you get 8
12.5, 20, 22.5, 32 is the way from least to greatest. Hope this helps.
45% of two-fifteenths is equal to 0.45 * 2/15
the product of (x+1) and one-twelfth is equal to (x+1) * 1/12 or (1/12x + 1/12)
Multiply them together to get your answer.
