What do you mean, the answer is 12 and we know that because we combine the numbers
A) 36/60 ~ 4 = 9/15 ~ 3 = 3/5 x 20 = 60/100 = 60% is what he spent on the shoes.
B) 100% - 60% = 40%
~ = divide
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>
