Answer: 6*24+(3*36)+(5*14) -23= 299

Answer:

Answer:: 299 blown-up balloons

Step-by-step explanation first I found

the number of heart-shaped balloons, 5 × 14 = 70. Next,

I added that number to the number of round balloons

and long balloons, 70 + 144 + 108 = 322 balloons

in all. Last, I subtracted the number of burst balloons,

so 322 – 23 = 299 balloons left.

HELP!!!!!!!!! An advertising sales representative has sales totaling $4500. For these sales, the representative earns a commission of $360. Which proportion could be used to find the commission amount for sales totaling $15,000? A. 360/4500 = 15,000/x

B. 360/4500 = x/15,000

C. 4500/x=360/15,000

D. x/360=4500/15,000

The commission amount for sales totaling $15,000 is shown by

360/4500 = x/ 150000.

What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

An advertising sales representative has sales totaling $4500 and for these sales, the representative earns a commission of $360.

Therefore, the commission fraction will be:

= Commission / Sales

= 360 / 4500

= 36/450

= 6/75

and, the commission on $15000 will be:

= 6/75 × $15000

= $1200

How do you solve this system of linear equation by substitution

x-3y=-12

y=2x+9

Finding x:

If y=2x+9, substitute y into the equation x-3y=-12.

You will get: x-3(2x+9)=-12

Now, distribute: x-6x-27=-12

Add like terms: -5x-27=-12

Add 27 to both sides: -5x=15

Divide both sides by -5: x=-3

Now, substitute this value of x into the equation to find y: y=2(-3)+9

Multiply: y=-6+9

Add: y=3

Here is the solution: (x,y)=(-3,3)

Hope this explanation helped!

How can you use functions to model linear relationships?

Answer:

a function is just a comparison between two quantities so when you go to plot the points, the input is x and the output is y.
