18/3 = 6
5*3 = 15
Answer:
m-9
-9+m
Step-by-step explanation:
m-9
The one way is the way it is given in the problem m minus nine
However it can also be written by interchanging the position of each term , but while interchanging we have to carry their sign along with them also.
Hence m can be taken on the left but with its + sign
and 9 can be taken in the right but with its sign that is -
Hence
m-9 can also be written as
-9+m
Answer:
4
Step-by-step explanation:
To solve this question you would first multiply all the dimensions of the pillar together. That would be:
2.5 x 2.5 x 12 = 75 square feet
Then you take the weight of the pillar and divide it by the amount of square feet:
12,000 / 75 = 160 pounds per square foot.
Answer:
5
Step-by-step explanation:
To solve this problem, we need to set up a system of equations. Let x represent the larger number and y represent the smaller number.
x + y = 17
x - y = 7
We can solve this system by adding them together. The y cancels out because y + (-y) = 0. After that, we solve for x
2x = 24
x = 12 (Divide both sides by 2)
Now that we know the value of x, we can substitute it into one of our original equations to solve for y.
12 + y = 17
y = 5 (Subtract 12 from both sides)
So, the smaller number is 5.
