Layla spent 25 minutes on
her math homework and
30 minutes on her social
studies homework. Elijah
spent 3 times as much time
on his homework. Which
expression represents the
number of minutes that Elijah
spent on his homework?
A 25 + (30 X 3)
B 25+ 30 + 3
C 3 x 25 + 30
D 3 x (25 + 30)

D

Step-by-step explanation:

25+30= time Layla spent. 3x time layla spent = elijah's time

I would say letter D because Elijah spent 3 times as much time on his homework as layla . Therefor layla's total minutes of homework would be 25+30 = 50 times 3 would then equal elijahs total number of minutes

Step-by-step explanation:

no he is not correct

Step-by-step explanation:

SA=113.04

SA=4pi*r^2

113.04=4*pi*r^2

113.04/4pi=r^2

8.995...=r^2

r= radical(8.995..)

r=2.9992...

r=3

the mistake happened when they forget to square the r in the SA formula
