First, we need to calculate how much money is the discount. We do that by multiplying 20% with 65$ = 20% * 65$ = 0,2 * 65$ = 13$
When we know how much money is the discount, we will subtract it from original value, and we will get the sale price of the tennis racket :
65$ - 13$ = 52$
Answer:
x = 1
Step-by-step explanation:
-5x-(-7-4x)-2(3x-4)
-5x + 7 - 4x - 6x + 8 First step is to factor all the numbers out so you have no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.
-15x + 15 In this step you combine like terms.
-15x = -15 Next you move the whole number to the other side of the equation by subtracting it from both sides.
x = 1 Finally you divide -15 by -15 to get x by its self.
Answer:
35.6047 inches
Step-by-step explanation:
The wiper blade moves in a circular way, where the radius is 30 inches.
To find how far the bug travelled, we just need to use a rule of three, where the length of the circunference relates to a angle of 360 degrees:
360 degrees -> 2 * pi * radius
68 degrees -> distance
distance * 360 = 2 * pi * radius * 68
distance = 2 * pi * 30 * 68 / 360 = 35.6047 inches
Answer:
68
