Step-by-step explanation:
total problems = 17+28=45
If she ca finish five problems in 20 minutes,
so...
for 45 problems
she take 45/5*20=180 minute = 3hour
Answer:
8
Step-by-step explanation:
-2 x -2 = 4
4 - (-28 / 7 = -4)
4- -4 = 8
Answer:
8/5 times 25/4 times 8/5
Step-by-step explanation:
Figure out how far it is from one side to another. The top is 46 + 8 = 55 across.
the bottom is also 55.
Figure out how far it is from the bottom up. The left side is 38 + 10 = 48. The right is also 48.
Put all of the distances together: 55+55+48+48 = ?
First combine like terms:
14d+-2d=12d
Then do -84 divided by 12 = -7
D= -7
