Sophia is 12. Four times that is 48. If her mother is 5 years less than this, she is 43.

(12 x 4) - 5 = 43

2. A soccer field is bordered on three sides by a parking lot of width x. The total

notsponge [240]

Answer: 50m

Step-by-step explanation:

this is the logical way I solved it:

1. Find the area of the entire area thing

300*200=60000

2. Subtract the area of the field from the area of the entire place

60000-30000=30000

3. Divide the area of the parking by three because there are three sides

30000 ÷ 3 = 10000

4. Divide 10000 by 200, not 300 because we want to find the side with one <em>x</em>, not two <em>x</em> (there are two sides adding on to the side with 300, but only one side on the side with 200)

10000÷200= 50

I know the steps are weird, but I know this is the right answer because this was on the unit test (same misspelling and everything lol) and during tutoring my teacher showed me how to do it, but of course I had to forget the steps.

Determine the equation of the line passing through the points <br> (4,-1) and (-2,-4)

jenyasd209 [6]

Answer:

y = 1/2x - 3

Step-by-step explanation:

the slope:

$m=\frac{-4-(-1)}{-2-4} =\frac{-4+1}{-6} =\frac{-3}{-6} =\frac{3}{6} =\frac{1}{2}$

the equation:

with the point (4, -1)

$y-(-1)=\frac{1}{2} (x-4)$

$y+1=\frac{1}{2}x-2$

$y=\frac{1}{2} x-2-1$

$y=\frac{1}{2} x-3$

I hope this help you

Consider the following expression and determine which statements are true.

Serhud [2]

Given:

$$\frac{7}{r}+2^{3}+\frac{s}{3}+11$

To find:

Which statement are true?

Solution:

Option A: The entire expression is a sum.

It is true because it performed addition operation.

Option B: The coefficient of s is 3.

$$\frac{7}{r}+2^{3}+\frac{s}{3}+11=\frac{7}{r}+2^{3}+\frac{1}{3}s+11$

It is not true because the coefficient of s is $\frac{1}{3}$ .

Option C: The term $\frac{7}{r}$ is a quotient.

If we divide 7 by r, we obtain a quotient.

So it is true.

Option D: The term $2^3$ has a variable.

It is not true because it does not contain any variable.

Therefore the entire expression is a sum and the term $\frac{7}{r}$ is a quotient are true statement.
