R = 3S
R + 6 = 2 (S+6)
Substitute the first equation in the second one:
(3S) + 6 = 2 (S + 6)
3S + 6 = 2S + 12
S + 6 = 12
<u>R = 18
</u>S = 6<u>
</u>
Check:
R is 3 times S now.
In 6 years, R will be (18 + 6) = 24, S will be (6 + 6) = 12.
24 = 2 x 12 yay

Answer:
A 2 ounce bag costs $1.2.
Step-by-step explanation:
With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.
6 ounce bag → 3.60
2 ounce bag → x
x=(2*3.60)/6
x=7.20/6
x=1.2
According to this, the answer is that a 2 ounce bag costs $1.2.
Answer:
2.50(10) + 3x = 135.97, x = 38.66
Step-by-step explanation:
This should be pretty simple.
Basically, we know that he bought 10 pairs for 2.50 so that's $25 right there.
Our total is 135.97 though-
so here, we take our total from the right side of the equation, and subtract 25 from that.
135.97 - 25 = 115.97
Since he bought three pairs, divide it by 3.
115.97 / 3 = 38.66
One pair of shoes costs $38.66 - hope this helps!
