Answer:
There are 77 more third graders than second graders.
Step-by-step explanation:
415-338=x
x=77
Answer:
Step-by-step explanation:
8x = 9x - 7
-x = -7
x = 7
9(7)-7= 63-7=56
8(7)= 56
13y+7+56=180
13y+63=180
13y=117
y=9
13(9)+7= 117+7= 124
5y-11+56=90
5y+45=90
5y=45
y=9
5(9)-11+9(7)-7= z
45-11+63-7=z
34+56=z
90=z
Answer:
2/5 of an inch per minute
Step-by-step explanation:
You can set up the rate as
. From here to find the amount of rain per minute, just multiply the numerator and denominator by 6/5 (The reciprocal of 5/6, so you can have one minute and see how much rains fills up in that time.)
You end with 2/5 of and inch per minute
13=w-14/2
divide 14 by 2
13=w-7
add 7 to the other side (inverse)
20=w
OPTIONAL: switch the equation around
w=20
Answer:
4+4+4=12
Step-by-step explanation:
Each cake needs cups of flour.
Therefore, the best estimate of the number of cups of flour that Nika used to make the three loaves is:
4 + 4 + 4 = 12
