Answer:
x = 17
Step-by-step explanation:
First, let's turn this into an equation:
twenty more ( +20 ) than four times a number ( 4x ) is equal ( = ) to the difference ( - ) between 139 and 3 times the number ( 3x ).
4x + 20 = 139 - 3x
Now let's solve:
Subtract 20 from each side:
4x = 119 - 3x
Add 3x to each side:
7x = 119
Divide each side by 7:
x = 17
Answer:
1.6(10-5)2= 1.6(5)2= (8)(2)=16
Step-by-step explanation:
Circumference = 2pi r
80/360 x 2pi x r = 24pi
r = 54
