You've already completed the first step by lining up terms with the same variables. Like addition, simply add them together column by column. x+(-x) equals 0 so it is cancelled out. 4y plus 6y is 10y. 9+11=20. We are left with 10y equals 20, so y equals 2. Then plug in the y value into either equation. I will use the first so x +4(2)=9. x must equal 1. Double check by plugging in both x and y into the second equation.
A coefficient is the number before any variables, which usually is a letter. <span>Variables that have no numbers have a coefficient of 1.</span>
a. 2 and 100
b. 1 and 4
c. 4 and 2
Answer:
We can determine which image is correct by the second equation, only in one of the images the line is correct.
X-y=1
So x = 1+ y
If y is one x should be two.
Only in one image that is true, the third image.
Answer:
Step-by-step explanation:
V=L×W×H
=3½in×1⅞×2¾
=3×2+1/2in × 1×8+7/8in × 2×4+3/4in
=7/2in × 15/8in × 24/4in
=2520/64 incube
so it's you tern to change into mixed fraction
sorry for that
but if it's helpful ❤❤
THANK YOU
