In order for two lines to be perpendicular, their gradients must multiply together to get -1
7*b=-1
7b=-1
Divide both sides by 7
So, the gradient of line b is -1/7
Original price of the swimsuit = x
If something was discounted 65%, that means you are paying 35% for it.
(100% - 65% = 35% or 0.35)
x(0.35) = 20.30
divide both sides by 0.35
x = 58
The swimsuit was originally 58 dollars.

(b) In 84 days, both inspectors will visit on the same day, because the LCM (least common multiple) of 7 and 12 is 84
hope it helps you!!!!!!!!!!
X = 2y
x-y = 30
x is the highest number and y is the lowest
Mark my answer brainliest please! Hope this helped!
