Suppose y is directly proportional to x. If y= 24 when x=2, what is the value of x when y= 144?

Answers

Answer:

Step-by-step explanation:

Because y=24 and x=2 you do the following:

144/24=6

Then, 6x2=12 because it is proportional

Or you could do 24/2=12 and 144/12=12

2r-9=-18
+9 +9
2r= -9
The answer is r=-9

Answer: 4.5

Step-by-step explains: 1) 2r - 9 = -18

2r - 9 + 9 = -18 + 9

2) ( 9 + 9 ) Add the numbers

( -18 + 9 ) add the numbers

2r = -9

3) Divide both sides of the equation by the same term

4) Cancel terms that are in both the numerator and denominator

• Mrs. Alvarez rents skis and poles for 3 days.
What is the total cost of the rental?
• The total cost of the rental is $

Answers

The value that Mrs. Alvarez will pay depends on the rental value of the ski and the poles per day, for example $144.

How to calculate the total loan cost of Ski equipment?

To know the total cost of the loan of the Ski equipment, we must know the loan price per day or per hour.

For example, suppose the loan price per hour is $2, then we would have to calculate how much one day is equivalent to and then multiply it by the total number of days.

$2 x 24 = $48

$48 x 3 = $144

Note: This question is incomplete because some information is missing. However I can answer it based on my general prior knowledge.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as D

Now , the value of D is

Substituting the values in the equation , we get

Let the total distance ran by Johnny be D = ran 2 miles north, 6 miles west, 3 miles north, 10 miles south, 8 miles east, and then 2 miles

So , D = 2 + 6 + 3 + 10 + 8 + 2

On simplifying the equation , we get

D = 31 miles

Hence , the distance is D = 31 miles

What value of x makes the equation below true? −2x=−36 A x=−34 B x=−38 C x=−18 D x=18

Answers

Answer:

D x = 18

Step-by-step explanation:

Given equation:

−2x = −36

Divide both sides by -2 to find x

−2x / -2 = −36 / -2

x = −36 / -2

x = 18

x = 18 makes the equation −2x = −36 true
