Each morning Rin rides 1.5 miles to school and then rides home in the afternoon. Later in the evening, she rides to the park and

back home. Over the 5 school days, she rides a total of 25 miles. Which equation can be used to find the distance she rides each evening?
1.5 + x = 25
1.5 + 1.5 + x = 25
5 (1.5 + x) = 25
5 (1.5 + 1.5 + x) = 25

Answer:

Last equation given in the list of possible answers:

5 ( 1.5 + 1.5 + x ) = 25

Step-by-step explanation:

We need to include in the total addition of miles ridden during the week:

a) 1.5 miles to the school

b) 1.5 miles from school back home

c) x miles for the evening ride

so for the miles ridden per day we have: "1.5 +1.5 + x"

Now, since per week she does 5 days like this, then we need to multiply the expression above by 5 in order to total the number of miles she rides weekly (25 miles)

5 ( 1.5 + 1.5 + x ) = 25

And we can use this equation to find the amount "x" that Rin rides in the evening.

The slope of the lines that passes through the points (-10,0) and (-13,3)
goldenfox [79]

Answer:

-1

Step-by-step explanation:

The formula to find the slope of a line is:

\frac{y_{2}- y_{1} }{x_{2} -x_{1} }

where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:

\frac{3-0}{-13-(-10)} =\frac{3}{-13+10} =\frac{3}{-3} =-1

This means the slope of the line is -1.

The price of a television was reduced from 250 to 200. by what percentage was the price of the television reduced
Murljashka [212]

Answer:

20%

Step-by-step explanation:

We can start by finding out how much the price of the television was reduced by.

250 - 200 = 50

Now, we need to know what percent of 250 is 50? Let x represent the percent of 250 that is 50. Using this, we can set up an equation:

<u />x\%\times 250=50

Notice that a percentage can also be written as that number over 100.

\frac{x}{100}\times250=50

\frac{250x}{100}=50

Reduce the fraction (250 and 100 have a common factor of 10)

\frac{25x}{10}=50

Reduce the fraction again (25 and 10 have a common factor of 5)

\frac{5x}{2}=50

Multiply both sides by two

5x=100

Divide both sides by 5

x=20

Therefore the price of the television was reduced by 20%.

You volunteer at an animal shelter on the weekends and today is adoption day! At the beginning of the event, you start with 44 c
densk [106]

The equation 44 - x + 2x = 50 can be used to determine the number of cats/kittens adopted.

Step-by-step explanation:

Given,

Number of cats/kittens at the event = 44

Number of cats/kittens at the end of event = 50

Let,

x be the number of cats/kittens adopted

Therefore;

Number of cats/kittens returned = 2x

Number of cats/kittens at the event - adopted + returned = Number at the end of event

44 - x + 2x = 50

The equation 44 - x + 2x = 50 can be used to determine the number of cats/kittens adopted.
