Answer:
y=1/4x+6
Step-by-step explanation:

Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)

Now let's add this new equation and our second equation.

We found x=-3
Now let's plug x's value in one of the equations to find y's value.

So we found y=5
Solution ;
(-3, 5)
Answer:
That would be obtuse
Step-by-step explanation:
Those are all more than 90 degrees!
Answer:
226.19
Step-by-step explanation:
pi * r^2 = area
The radius = diameter/2 = 6
pi * 6^2 * 2 = area of 2 tortillas
72pi = area of 2 tortillas
That rounds to 226.19
Answer:
18
Step-by-step explanation:
Sum the parts of the ratio, 3 + 4 = 7
Divide the amount of marbles by 7 to find the value of one part of the ratio
42 ÷ 7 = 6 ← value of 1 part of the ratio, thus
red marbles = 3 × 6 = 18
