The two angles given are vertical angles which mean they are the same.
x +40 = 60
Subtract 40 from both sides:
x = 20
It would be 21 because 7 times 3 equals 21 and the way you get that is 3 drawings per paper
If they proportional, it implies
(x+2)/(x-1) = 8/10
Or 10x +20 = 8x-8
Or 2x = -28 or x = -14
To solve y, we need to make y the only value on the left hand side of the equation:
Therefore the value of y = -14+3x.
Hope it helps!
The original price was $70.2. (If it’s not supposed to have cents then it’s just $70).
This is because you convert 35% to 1.35. Then, you multiply 52 by 1.35. That’ll give you 70.2.
