Answer:
(-2, -4)
Step-by-step explanation:
Given:
The system of equations to solve is given as:
In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,
Dividing both sides by 3, we get:
Now, 
Therefore, the solution is (-2, -4)
Answer:
9
Step-by-step explanation: So we need to write and solve an equation to solve for m, which is 12. Simply plug in 12 for m in the equation.
Step 1: 2-x/4+10
Step 2: 2-12/4+10
Step 3: 2-3+10
Step 4: -1+10=9
Plug 12 in for x
12 divided by 4 is 3 and 2-3 is -1
-1 + 10 is 9 -1 + 10 is 9

Answer:
Araceli uses 6.15 pints of white paint to paint her bedroom walls
Step-by-step explanation:
8.2 pints= blue and white paint
blue paint= 8.2/4
white paint= 8.2 - (8.2/4)
8.2/4 = 2.05
8.2 - 2.05= 6.15
Find the volume of the rectangular prism by solving the equation V = 20 × 20 × 16.
V = 6,400
Now all you have to do is get 3/4 of that number. For me, it's easier to multiply decimals, so I will change 3/4 into it's decimal form, .75
V = 6,400 × .75 = 4,800.
The volume of the tank is 4,800 cm³.
Answer:
It is a positive number.
