"Sum" means at least two numbers added together.
There's no such thing as the sum of a single number.
1) 3x-8 =x
subtract x from both sides
2x-8=0
add 8 to each side
2x=8
divide both sides by 2
x=4
1) Nashville = center = (-58, 55) => Xc = - 58miles, Yc = 55miles
2) radius = 8 miles
3) General equation of a circle: (x - Xc)^2 + (y - Yc)^2 = radius^2
4) equation of the circle that represents radar coveraga:
(x - (-58) )^2 + (y - 55)^2 = 80^2
=> (x + 58)^2 + (y - 55)^2 = 6400
Answer: (x + 58)^2 + (y - 55)^2 = 6400
10 quarts, how many pints?
2 pints = 1 quart
10*2 = 20
Answer: 20 pints.
Answer: 144
Step by step: In order to solve this easily, you should convert 3/5 into a decimal. In order to do that, you have to divide the numerator by the denominator. 3 divided by 5 = 0.6. Then you multiply 240 by 0.6 to get your answer, 144.
