C is x=1.5. Can’t be bothered to do the rest
Answer:
Step-by-step explanation:
add all of them up, Julie, 6 + 12 + 3 + 4 = 25
there are 25 total students. now divide each of the number of people that speak that language by the total students
6/25 = .24 = 24%
12/25= .45 = 48%
3/25 = .12 = 12%
4/25 = .16 = 16%
Also, if you want to just check, see if the percentages add to 100%

Equality Properties
Step-by-step explanation:
<u>Step 1: Define Equation</u>
6n + 7 = 55
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 7 on both sides: 6n = 48
- Divide 6 on both sides: n = 8
<u>Step 3: Check</u>
<em>Plug in n into the original equation to verify it's a solution.</em>
- Substitute in <em>n</em>: 6(8) + 7 = 55
- Multiply: 48 + 7 = 55
- Add: 55 = 55
Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.
Answer:
8640 square inches
Step-by-step explanation:
There are 12 inches in one foot so there would be 12 * 12 = 144 square inches in 1 square foot. Therefore, there are 144 * 60 = 8640 square inches in 60 square feet.
Area formula for rectangles: L x W
Answer: 3 x 2a + 3 x 5 = 3 x 2a x 5
You know that the expressions are equivalent, because when you solve for a you get a = 5/8 or 0.625
