Answer:
y= -2x+23
Step-by-step explanation:
Subtract 2x over
Xy= 120
x= 7+y
(7+y)(y) = 120
y^2 + 7y - 120 = 0
(y + 15) (y - 8) = 0
Since we are finding two positive numbers,
If y= 8 then x= 15
The two numbers are 8 and 15
Answer:
Rows 126
last row has 41
last row is not full because its an odd number
Step-by-step explanation:
For this case we have the following equation:
If we multiply both sides of the equation by 3 we get:
---> Multiplication Property of Equality
Applying the distributive property we have:
---> Distributive Property
Adding 1 on both sides of equality we have:
---> Addition Property of Equality
Subtracting 
on both sides we have:
---> Subtraction Property of Equality
Finally, dividing by -4 on both sides we have:
---> Division Property of Equality
Answer:
No, they are not equivalent
