Solve the proportion below. 55/x=5/6 x=? A. 50 B. 60 C. 56 D. 66
2 answers:
Answer:D)66
Step-by-step explanation:
55
/x
=
5/
6
Step 1: Cross-multiply.
55
/x
=
5/
6
(55)*(6)=5*x
330=5x
Step 2: Flip the equation.
5x=330
Step 3: Divide both sides by 5.
5x
/5
=
330
/5
x=66

Answer:
the product is 6/Y^8
Step-by-step explanation:
Answer:
∠a = 1/2(95) = 47.5°
∠b = 90°
arc = (180 - 47.5 - 90)(2) = (42.5)(2) = 85°
Say arrives at the library at 5:42
X = measure of 1st angle
y = measure of 2nd angle
x + y = 180
y = 3(x+25)
Therefore,
x + 3(x+25) = 180
x + 3x +75 = 180
4x = 105
x = 26.25
So the measure of the 1st angle is 26.25 and the 2nd is 153.75
