so
by proportion
Find how long will it take the printer to print 120 photos

step 2
Khalil’s printer
we know that

Answer:
hmmmm........
Step-by-step explanation:
radius is 4/2=2m
volume of the cylinder is equal
to πr^h
i.e, π(2m)^2×7m
≈88 m^3
What’s the question lol ? The photos all black
Area of this rectangle
4×3=12cm^2
formula
long side×short side=area of this rectangle
Maria has 19 hats.
b=beth
m=maria
Equations: 2b+5=m
b+m=26
plug in 2b+5 for m in equation 2: b+2b+5=26
add like terms: 3b+5=26
subtract 5 from both sides: 3b=21
Divide 3 from both sides: b=7
now plug in 7 for b: 7+m=26
subtract 7 from both sides: m=19
m=Maria
therefore Maria has 19 hats
