I need help on this one someone help me please ​
WARRIOR [948]
I believe the answer is 3. Because if you have a ratio that is 2:1 and Evan has 6 then it would be 6:x and so you just divide two? I hope that is correct! :)

What is the this expression in standard form?: 6(5r-4)-2(r-7s-3)
Thepotemich [5.8K]

Use distrubutive property <em>a(b + c) = ab + ac</em>

6(5r - 4) - 2(r - 7s - 3)

= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)

= 30r - 24 - 2r + 14s + 6

= (30r - 2r) + 14s + (-24 + 6)

<h3>= 28r + 14s - 18</h3>
