Hi there!
I will help you by telling you how to solve them. I will show you one of the ways to solve this.
The first way you can solve this is by multiplying and then reducing the fraction. To do this all you need to do is multiply the numerators together and then you multiply the denominators together, after you do this you simply reduce the fraction to it's lowest possible numerator and denominator. For example:
Then to reduce:
÷ 
= 
÷ 
= 
Hope this helps!

Answer:
the answer will be the first one.
Step-by-step explanation:
X = -3/2 and is first degree
Answer:
X = 8
Step-by-step explanation:
5x + 2(4x-16) = 72
multiply 2 into the parenthesis
5x + 8x-32 = 72
combine like terms
13x - 32 = 72
add 32 on both sides
13x = 104
divide by 13 on both sides
X = 8
Answer:
≈ 18.8 cm
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
The central angle is equal to the arc subtending it, that is 60°
arc = 2πr × 
= 2π × 18 × 
= 36π ×
= 6π ≈ 18.8 cm ( to 1 dec. place )
