Substitute the given value of y into the equation -3x-2y=-12
Distribute -2 through the parentheses
Collect like terms
Move the constant to the right-hand side and change its sign
Calculate the sum and divide both sides of equation by -13
Now, Substitute the given value of x into y=5x-7
Multiply the numbers
Subtract the numbers
The possible solution of the system is the ordered pair (x,y)
Answer:
2
Step-by-step explanation:
First plug in all the numbers into the variables.
3(2^2) - (18 - 4(2))/ 3^2 - 8
This is what your equation should look like after you plugged in 2 for the a and 3 for the b. Then you solve them individually; starting with 3(2^2). 2^2 is 4 and 3 × 4 is 12. So now the equation should look like this:
12 - (18 - 4(2))/ 3^2 - 8
Next, we can solve for (18 - 4(2)). So -4 × 2 is -8, and then you have (18 - 8). That answer would be 10. You should have 12 - 10 on top now, and the answer to that is just 2. Now your equation should look like this:
2/ 3^2 - 8
Now onto 3^2 - 8. 3^2 is 9 because that would just be 3 × 3. Now you have 9 - 8, which is 1. So now you should be left with:
2/1
And that's your final answer.
I think the answer is -2,I guess?
Answer:
if the track is 3/4 miles long and each person ran 2, 2, and 3 laps then your answer would be 5 and 1/4 miles.
