The work and answer is shown in the image below. Just set the variables and solve.
Answer:
Step-by-step explanation:
x = - 48/-8 = 6
c = c^2/c^1 = c^(2-1) = c^1
d = d^4 / d^1 = d^(4 - 1) = d ^3
x = 6
e = 1
f = 3
Set up a ratio to find the number of pages read in 80 minutes:
40 pages/ 50 minutes = x pages/ 80 minutes
Cross multiply:
50x = 3200
Divide both sides by 50:
X = 3200/50
X = 64
He will read 64 pages in 80 minutes.
200 -64 = 136
There will be 136 pages left.
Answer:
f = -8
Step-by-step explanation:
7(f+3)+9=5(f-2)-3f
7f + 21 + 9 = 5f - 10 - 3f
7f + 30 = 2f - 10
5f = -40
f = -8
