Y - 3 = 2x -1 ...y = 2x + 2

x +3 = y - 1

replace y = 2x + 2 into x +3 = y - 1

x +3 = 2x + 2 - 1
2x -x = 3 -1
x = 2

y = 2x + 2
y = 2(2) + 2 = 6

answer x = 2 , y = 6 first choice

Shelby bought a 2-ounce tube of blue paint. She used 2/3 ounce to paint the water, 3/5 ounce to paint the sky, and some to paint

irina1246 [14]

Answer:

The amount of ounce used for paint is $\frac{9}{15} ounce$

Step-by-step explanation:

used amount for water is $\frac{2}{3}$ ounce.

used amount for sky is $\frac{3}{5}$ ounce.

thus, the total amount used is $\frac{2}{3}$ + $\frac{3}{5}$

= $\frac{19}{15}$

Thus the total unused amount is 2 - $\frac{19}{15}$ = $\frac{11}{15}$ .

But the remaining amount is $\frac{2}{15}$ .

Thus used amount for flag is $\frac{11}{15}$ - $\frac{2}{15}$

= $\frac{9}{15}$

How do you solve 0.8=6-2.5x

photoshop1234 [79]

X=2.08

To solve you need to first get x by itself. To do that you want to subtract 6 from both sides (get 6 away from x and put on other side) which will leave you with -5.2=-2.5x next isolate x by dividing -2.5 on both sides to then get 2.08=x
