Answer: A. And B.
Step-by-step explanation:
(16a+72)/4
=4(4a+18)
(16a+72)/8
=8(2a+9)
Answer:
Step-by-step explanation:
log8 62 = x1
8^x1= 62
8^2 =64 >62 so <u>x1<2</u>
log7 50=x2
7^x2=50
7^2=49<50 so <u>x2>2</u>
we have, x1<2 and 2<x2
x1<2<x2
x1<x2
log8 62<log7 50
Answer:
14cm
Step-by-step explanation:
formula of a rectangular container is LBH and we were given that LBH is 2*11*20 which is equal to 440cm.
Now when the water is transferred into a hollow cylindrical container.the formula for that is 2pierh.440=2*22/7*5*h
440*7=220h
3080=220h
h=14cm

Step-by-step explanation:
A: -vp + 30 < 45
Subtract 30 from both sides.
-vp < 15
Divide both sides by -v.
p > -15/v
( when dividing a negative, the < sign must be changed to >)
B. 3w - 6r = 30
Subtract 3w from both sides.
-6r = -3w + 30
Divide both sides by -6
r = (-3w + 30)/ -6
simplify the right side
r = (w - 10)/2
OR
r = (-3w/-6) + (30/-6)
r = w/2 - 5
