alexgriva [62]

Answer:

The variable are

A and B

Step-by-step explanation:

Generally we can define a variable as a name of a placeholder representing a value now considering the option to be selected from we see that

The students' verbal SAT scores is a variable because it is a phrase or a place holder that represent a value (in the is case a numerical value) which the score its self

The second option The students' percentage of words that were correctly recognized on the original list is also a variable because it is a placeholder of a name (in this case a phrase ) that represented the actual value itself

Trisha and Byron are washing and vacuuming cars to raise money for a class trip. Trisha raised $38 washington 5 cars and vacuumi

pshichka [43]

Answer:

The amount they charged to wash a car is <u>$6</u> and vacuum a car is <u>$2</u>.

Step-by-step explanation:

Given:

Trisha and Byron are washing and vacuuming cars to raise money for a class trip.

Trisha raised $38 washington 5 cars and vacuuming 4 cars.

Byron raises $28 by washing 4 cars and vacuuming 2 cars.

Now, to find the amount they charged to wash a car and vacuum a car.

Let the amount charged for washing a car be $x.$

And the amount charged for vacuuming a car be $y.$

So, the total amount Trisha raised:

$5x+4y=38.$ .......(1)

And, the total amount Byron raised:

$4x+2y=28.$

Now, to get the amount they charged to wash a car and vacuum a car we use elimination method:

$5x+4y=38\\4x+2y=28......\times 2$

$5x+4y=38\\8x+4y=56$

$-3x=-18$

$3x=18$

<em>Dividing both sides by 3 we get:</em>

$x=6.$

<u>Amount charged to wash a car = $6.</u>

Now, putting the value of $x$ in equation (1) we get:

$5(6)+4y=38.$

$5\times 6+4y=38$

$30+4y=38.$

<em>Subtracting both sides by 30 we get:</em>

$4y=8.$

<em>Dividing both sides by 4 we get:</em>

$y=2.$

<u>Amount charged to vacuum a car = $2.</u>

Therefore, the amount they charged to wash a car is $6 and vacuum a car is $2.

How to solve ((-9)×(-5)-9)÷(-12)

goldenfox [79]

Answer:

-3

Step-by-step explanation:

Simplify the following:

(-9 (-5) - 9)/(-12)

-9 (-5) = 45:

(45 - 9)/(-12)

| 3 | 15

| 4 | 5

- | | 9

| 3 | 6:

36/(-12)

The gcd of 36 and -12 is 12, so 36/(-12) = (12×3)/(12 (-1)) = 12/12×3/(-1) = 3/(-1):

3/(-1)

Multiply numerator and denominator of 3/(-1) by -1:
