No, when you substitute it into the first equation for x and y it does not equal 36 this it's not a solution
(-3)-(3)(11)=36
-3-33=36
-36 =/ 36
We solve 6 + 4
6 + 4 = 10.
Square root of 10:

<span>The square root of 10 is a periodic decimal (decimal that has infinite decimals, worth the redundancy)
What is that periodic decimal?

The equation that models this situation is z = 7.9y + 12.
A linear equation is a function that has a single variable raised to the power of 1. An example is x = 4y + 2.
Where:
- 2 is the constant
- x = dependent variable
- y = independent variable
From the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.
z = 7.9y + 12
Here is the complete question: A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began. write an equation in standard form to model the linear situation.

Answer:
121
Step-by-step explanation:
31+90 = 121
180 - 121 = 59
