Answer:
Step-by-step explanation:
First, you want to do inverse operations like I said on the last equation
Just divide -4 with 64
You have to flip the inequality sign because you divided by a negative
Answer: g ≥ -16
Now what is greater than or equal to -16?
Answer =
-16
-11
-6
-13
Surface area = area of 2 triangular sides + area of the roof + area of the base.
= 2 * 1/2 * 6 * 4 + 2 * 5*7 + 6 * 7
= 24 + 70 + 42
= 136 units^2
The equation (1) is divided by 2 to create new equivalent system of equations.
Step-by-step explanation:
The given systems of equations are:

Considering 8y instead of 8 in eq(1)
We need to identify what action was completed to create this new equivalent system of equations? 
Comparing given equations we came to know that equation(1) is divided by 2 to get the new equation i.e

While second equation is same as given.
So, The equation (1) is divided by 2 to create new equivalent system of equations.

Answer: 87/13
Step-by-step explanation: You take you 5 and times it by 13 and + 9 because the equation is saying 13/13 5 times plus the 9/13,
So 6*13 = 78 78+9=87 and then you take the 87 and put it over the 13,
So, now you have your answer: 87/13
