Answer: True</h3>
Explanation:
Technically you could isolate any variable you wanted, from either equation. However, convention is to pick the variable in which isolating it is easiest, and most efficient.
The key thing to look for is if there's a coefficient of 1. This is found in the second equation for the y term. Think of -4x+y = -13 as -4x+1y = -13. Due to the coefficient of 1, when solving for y we won't involve messy fractions.
If you were to solve for y, then you'd get y = 4x-13, which is then plugged in (aka substituted) into the first equation. That allows you to solve for x. Once you know x, you can determine y.
Answer:
x=14.02
Step-by-step explanation:
Use b= to solve for the missing side in the triangle. You will get a rounded answer of 8.49. Then you multiply that by 2 and subtract that value from 31. Then that will be your answer.
I'm taking you at your word. I think these sentences are true
because you said them:
-- Samuel has read 3/6 of his assignment.
-- Judy has read 4/8 0f her assingment.
-- Their assignments were the same size.
Firstly, you have to isolate the X on one side if the equation by doing that you have to divide the numbers that are on the same side of the equation as part of the X.
Here you go!! Hope this helps
