<span>A number, half of that number, and one-third of that number are added.
This statement can be expressed as:
x + (1/2)x + (1/3)x
The total is 22
</span>x + (1/2)x + (1/3)x = 22
So let's look for x
x + (1/2)x + <span>(1/3)x = 22
</span>(6x + 3x + 2x) / 6 = 22
11x = 132
x = 12
So the original number is 12.
The first step of finding the percent tip, we must find how much tip she paid:
Tip = $38.61 - $33 = $5.61
To find the percent tip, we must divide the tip amount by the amount she paid before the tip
$5.61 / $33 = 0.17 --> 17%
Thus the percent tip is 17%
Hope that helps!
Answer:
Step-by-step explanation:
You have to start out with the distributive property 5 times 2 times c is 10+5c; now you have to subtract 5c on both sides in the upside down T chart, now its 10=45+c and your answer will be c=4.5.
Setup
remember is means =, and of means *
Writing across the words
15 = x * 39
15/39 = x
x =0.3846 = 38.46%
