Answer: $20
Step-by-step explanation:
20% of 25 is 5
You can figure that out by writing 20/100 (percents are out of 100)
Simplified 20/100 would be 1/5
so we are finding 1/5 of 25
1/5 x 25/1 = 25/5 or 5
So the discount is $5
$25 - $5 is $20
<span>Lets write this as a ratio 1st.
</span>When Working with
ratios we have to be VERY careful because you HAVE to put the numbers for the
ratio in the way it says. If you change the order than your changing the
answer. Ratio's can be written in 3 different ways.
Like this:-
a to b
a:b

</span><span>For every 5 coins Carmen gives Frankie 2
5:2
9:?
5 - 2 = 3
So 3:2
9 ÷ 3 = 3
3 × 2 = 6
So, Caamen has 9 coins and Frankie has
6 coins.
Hope I helped ya!!! xD </span>
The answer would be Y=2x+8
3(-2y-7)+8y
First distribute the 3
-6y-21+8y
Combine like terms
2y-21
Get the y by itself
2y=21
Divide by 2
Y=10.5
The answer should be 3 but if not sorry
