Answer:
They all equal 
because they all give 
Step-by-step explanation:
They all equal because they all give
Done by writing three equations with one random number and the desired result, , returning the answers above.
This is a system of linear equations. First, you can add the two equations together to eliminate the y so that you can solve for x:
-5x + -7x = 0 + -96
-12x = -96
x = 8
Use x to solve for y:
-5 * 8 + 8y = 0
Add 40 to both sides and divide by 8:
y = 5
So, x = 8 and y = 5.
your answer's correct.
Step-by-step explanation:
Answer:
The answer would most likely to eight. If not use the formula Base x Height
Step-by-step explanation:
Cross multiplying we get
x^2 = 2*7x
x^2 = 14x
x^2 - 14x = 0 is the answer
