Answer:
44 pages
Step-by-step explanation:
To calculate 70% of 147, divide 147 by 100 to find the number of pages per 1%, then mulitply by 70 to find 70%
(147 ÷ 100) x 70 = 102.9 = 103 (rounded to the nearest integer)
To calculate how many pages are left, subtract 102.9 from 147:
147 - 103 = 44
addition property of equality. hope that helps!
Yes, they are adding 100 every time.
k = -5
y = -8x - 73 and x = -4
y = (-8) (-4) - 73 = - 41 : intersect at (-4 , - 41)
(-4 , - 41) must at y = 9x + k
-41 = 9*(-4) +k
k = -41 + 36 = -5
y = 9x - 5 x<-4
