Each pallet of cement weighs 303.5 pounds. You just have to divide 4,856 by 16
The first step for solving this equation would be adding -2 to both sides of the equation.
Answer:
40 students participate only in music.
Step-by-step explanation:
When you add the two groups together, you get 50 + 60 = 110. But there are only 100 students, so 10 of them must have been counted twice (they do music AND sports. Put 10 in the middle part of the Venn diagram (image2).
Subtract 10 from each of the two groups to find the number of students taking only one of the two subjects. For example, there are 50 music students, but 10 of them also do sports, so 50 - 10 = 40 students do only music. (There are 60 - 10 = 50 students who participate only in sports.) (image3).
Answer:
A. 57m B. 130m
Step-by-step explanation:
For problem A:
87m up a cliff - 30m up a cliff = 57m up a cliff
These are all positive values
For problem B:
100m above is talking about a positive value, making this a positive number
30m below is talking about a negative value, making this number -30
0 meters represents the surface
As you can see, this is forming a number line as of which
below the surface------------------------0m-------------------------above the surface
by substitution,
-30-----------------------------------------------0-------------------------------100
therefore, 100 - -30 = 130 meters
