so she saved $20 and that was 40% of the regular price, let's say the regular price is "x".
if 20 is 40%, what is "x" or namely the 100%?
The two circles are equally inscribe inside a rectangle which means that its length is equals to the diameter of a circle and the width is two tines the diameter of a circle.
A. The area of the rectangle using the R. is Area = 2R*4R
B. The perimeter is express as Perimeter = 2(2R*4R)
Answer:
P = 62° Q = 28°
Step-by-step explanation:
Let x = measure of angle Q
then y = measure of angle P
Now x + y = 90 and 2x + 6 = y
Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.
3x + 6 = 90
3x = 84
x = 28
y = 2(28) + 6 = 56 + 6 = 62
Check: 28 + 62 = 90
Answer:
x = 23
Step-by-step explanation:
3x + 7 = x + 53 because vertical angles are congruent. So just solve...
3x - x + 7 = x + 53 - x
2x + 7 = 53
2x + 7 - 7 = 53 - 7
2x = 46
x = 23
Answer:
neither
Step-by-step explanation:
when slopes are the same its parallel
when slopes are multiplied and it equals -1 they are perpendicular
