Answer: 5
Step-by-step explanation:
weekday hours x*2
weekend hours y*10
x+y=26
2x+10y=220
----------------------
x=26-y
2(26-y)+10y=220
52-2y+10y=220
8y=220-52
8y=168
y=168/8
y=21
x=26-21=5
x=5

Answer:
<u>So, the way a ratio works is </u><u>"for every 1 of this, we have 4 of this"</u><u> for example. (the ratio I just described would be 1:4.) </u>
<u />
I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.
So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.
So:
240 ÷ 3 = 80
If your ratio is 9:3, then 80 is your answer.
<u>Hope this helps and have a nice day!</u>
