8-pack jump ropes cost $10.48 what is the price of 1-pack of jump rope?

Answer:

18/45

Step-by-step explanation:

First you set 2/5 equal to x/45.

Then you see what number you need to multiply 5 by to get 45

Multiply 2 by the number you got and you get x.

The equivalent fraction for 2/5 with a denominator of 45 is 18/45.

We need to figure out what number we can multiply the numerator and denominator by to get the necessary denominator in order to discover an equivalent fraction for 2/5 with a denominator of 45.

The denominator must be multiplied by 9 in order to be converted from 5 to 45 (45 ÷ 5 = 9). To keep the ratio and get the equal fraction, we will also multiply the numerator by 9.

2/5 x 9/9 = (2 x 9) / (5 x 9) = 18/45

As a result, 18/45 is the corresponding fraction for 2/5 with a denominator of 45.

Answer:

y=-2/3x+3

Step-by-step explanation:

First, identify the slope you need for your equation. The keyword here is "parallel" so the slope you need is the same as the given slope (-2/3).

Next, use the ordered pair (6,-1); it's on the line that you need to find the equation for. Using slope-intercept form (y=mx+b), plug the -1 in for y, plug the 6 in for x, and plug in your slope of -2/3 for m. Solve for b, your y-intercept. You should get 3.

You have your slope and y-intercept now. Create your equation:

y=-2/3x+3.

Answer:

[tex]x=89[/tex]

Step-by-step explanation:

We can plug into the formula for the mean to get [tex](87+73+84+82+x)/5=83[/tex].

We can combine like terms on the left side to get [tex](326+x)/5=83[/tex].

We can multiply by [tex]5[/tex] on both sides to get [tex]326+x=415[/tex].

We can finally subtract [tex]326[/tex] from both sides to get [tex]x=89[/tex].

So, the answer is [tex]\boxed{x=89}[/tex] and we're done!

Step-by-step explanation:

I used a calculator, pls let me know if im incorrect

Hey there!/¡Hola!

(3a + 4b) - (5a - 2b)

= 3a + 4b - 5a - 2b

COMBINE the LIKE TERMS/COMBINAR los TÉRMINOS LIKE

[tex]y = x + \pi[/tex]

Step-by-step explanation:

We need to find the slope of the line tangent to y at [tex]x=-\pi[/tex] and we can do that by calculating the derivative of y at that point. We know that

[tex]y'(x) = \dfrac{d}{dx}(\tan{x}) = \sec^2{x}[/tex]

and

[tex]y'(-\pi) = \sec^2(-\pi) = 1[/tex]

To find the equation of the tangent line, we know that the line passes through the point [tex](-\pi, 0)[/tex] so we can write the slope-intercept form of the line's equation as

[tex]0 = (-\pi) + b \Rightarrow b = \pi[/tex]

Therefore, the equation of the line tangent to the point [tex]x = -\pi[/tex] is

[tex]y = x + \pi[/tex]

The graph of the two functions is shown above.

Answer:

17 3/4 feet long

or

17.75 feet long

Step-by-step explanation:

11 1/2 -> 11 2/4 (just multiplying numerator/denominator by 2

11 2/4 + 6 1/4 = 17 3/4

Answer:

17 3/4

Step-by-step explanation:

Convert 6 1/4 to an improper fraction (25/4)

Convert 11 1/2 to an improper fraction (23/2)

Multiply 23/2 by 2/2 to get a common denominator

which makes 25/4 +23x2/4

And 25+46=71

So 71/4

Then to change it back into a mixed number you divide 71 by 4 and get

17 3/4

Answer:

D.4/8

Step-by-step explanation:

Step-by-step explanation:

the inverse function simply calculate the original x it of a given y. so, we need to transform the original function to calculate x instead of y.

and then, at the end to make it a formally correct function definition, we rename x to y and y to x.

y = x + 3

x = y - 3

=> to make it a formally correct function definition

y = x - 3 = h(x)

Answer:

Victor has 18 trophies

Step-by-step explanation:

Let's set up "let statements"

Let d = Dean's trophies

Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...

Let 2d = Victor's trophies

Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...

2d + d = 27

Combine like terms...(2d and d)

3d = 27

Divide 3 on both sides to isolate the variable "d"

3d ÷ 3 = d

27 ÷ 3 = 9

So...

d = 9

That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...

2 · 9 = 18

Therefore, Victor has 18 trophies!

Hope this helps :)
