We need to use the variables m and n to represent both numbers.
Their sum must equal -15. Therefore, we can write the next equation:
m + n = -15
If one number is five less than the other, we need to choose one variable and then we can write it in terms of the other variable. Then:
n = m-5
To find the value for each number, we can replace the n equation on the first equation:
m + n = -15
m + (m-5)= -15
Then:
m + m - 5 = -15
2m -5 = -15
Solve the equation for m:
Add both sides 5 units:
2m - 5 +5 = -15+5
2m = -10
Divide both sides by 2:
2m/2 = -10/2
m = -5
Finally, replace the m value on the first equation:
m + n = -15
-5 + n = -15
Then, solve the equation for n:
Add both sides by 5:
-5+5 + n = -15 +5
n = -10
Hence, both numbers are m=-5 and n= -10.
The equations separated by a comma are m + n = -15,n = m-5.
The numbers separated by a comma are -5,-10.

Although you do not give the rates I assume the answer is D as it is the only positive multiplication. You cannot have negative height.
Answer:
H = 11m
Step-by-step explanation:
As we know, volume = length * breadth/width * height
Given,
length = 6m
Breadth/width = 3 1/2 or 3.5
Height = ?
So, l * b * h = v
=> 6m * 3.5m * h = 231m
=> 21m * h = 231m
=> h = 231m /21m = 11m
Therefore, height = 11m / 11metres
Hope this helps
Actually Welcome to the Concept of the Arithmetic Operation.
====> 5(3+6) + 5*3/ 5(4-1)
=====> 5(9) + 15 / 5(3)
=====> 45+15 / 15
=====> 60/15
======> 4
answer is 4
Answer:
(1,2.16), (2,4.32) and (3, 6.48).
The solution (1,2.16) means that 1 cubic units of pudding weighs 2.16 pounds.
The solution (2,4.32) means that 2 cubic units of pudding weighs 4.32 lbs.
Step-by-step explanation:
The equation y=2.16x describes the weight y of x cubic pounds of pudding.
The three solutions of this equation are (1,2.16), (2,4.32) and (3, 6.48).
Now, solution (1,2.16) means that 1 cubic unit of pudding weighs 2.16 pounds.
Again, solution (2,4.32) means that 2 cubic units of pudding weigh 4.32 lbs. (Answer)
