Add the x^3:- 6 x3 + 3x3 = 9x3
x's:- -8x + 6x = - 2x
-5 + 2 = -3
the first choice is the correct one
Answer:
70 cents
Step-by-step explanation:
all you have to do is divide $3.50 and 5 :)
<span>With a boys to girls ratio of 8:7, this means 8/15 of the campers are boys and 7/15 of the campers are girls.
We are told that there are 195 total campers.
To find # of boys: 195 (the total # of campers) x 8/15 (fraction of the campers that are boys) = 104 boys
To find # of girls: 195 (total # of campers) x 7/15 (fraction of the campers that are girls) = 91 girls
Note: If you do not know how to multiply by fractions, let me know, I have another trick that takes more time but doesn't require the use of fractions.

First you order them from least to greatest.
5, 6, 7, 9, 10, 12, 12
Then you cross off one number from each side until you get to the middle
Medial = 9

General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Geometry</u>
Step-by-step explanation:
<u>Step 1: Set up equation</u>
3x = x + 26
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>x</em> on both sides: 2x = 26
- Divide 2 on both sides: x = 13
