Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if necessary.

C=24x+80
R=44x
Break Even point (_ , _)

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given

C=24x+80

R=44x

To determine

What is the break-even point?

Given that

C represents the cost in dollars

R represents the revenue in dollars.

At the break-even point Cost (C) equals Revenue (R), so

R = C

44x = 24x+80

44x-24x = 80

20x = 80

divide both sides by 20

20x/20 = 80/20

x = 4

Thus, at x = 4 the value of Cost (C) equals Revenue (R).

i.e.

C = 24x+80 = 24(4)+80 = $176

R = 44x = 44(4) = $176

I am having trouble on algebraic expressions and numerical expression what is the easiest way to solve my problem and im in 6 th grade

Answers

Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.

Step-by-step explanation:

First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).

For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.

While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.

Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.

For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Two negatives make a positive

6 + 3

9 units distance

Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.

if y=3x^3+x^2-5 and z=x^2-12 what polynomial is equivalent to 2(y+z)

Answers

Answer:

2y + 2z

6x³+2x²-10 + 2x²-24

6x³+4x²-34 ■

Step-by-step explanation:

The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

What is Polynomial?

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.

Here, y = 3x³+x²-5 and z = x²-12

Now,

2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )

2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )

2 ( y + z ) = 6x³ + 4x² - 34

Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

Best Buy is having a HUGE sale. All items are 60% off. How much will you pay for a tv that originally cost $1200 including 5% sales tax?

Answers

Answer:

$480

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Original cost including sales tax = $1,200

Discount = 60%

So, we can calculate the cost of TV after discount by using following formula:

Cost of TV after discount =  $1,200 - ( $1,200 × 60%)

= $1,200 - $720

= $480

Hence, Cost of TV after discount is $480.

Mark's favorite tree is a large oak

length of his shadow and the length
of the shadow cast by the tree. Mark,
who is 5 feet tall, cast a shadow 10
feet long. He found that the tree's
shadow was 140 feet long. How tall is
the tree?

Answers

Answer:  The shadow of the tree is 280 feet long.

Step-by-step explanation:

We can use a ratio to solve this:

Use the Height to shadow for each. This works because the fractions must reduce to the same equivalent.

5/10 = 140/x

We can see that 5/10 is 1/2, so we need another fraction using 140 as the numerator that is equal to 1/2.  That's easy here: Multiply 140 × 2 to get the new denominator, 280 that replaces x. That is the length of the shadow.

If you have a less obvious ratio, you can use Cross Multiplication to solve the unknown value in the ratio:

5/10 = 140/x  Cross multiply the numerator of the left side times the denominator on the right side, and the denominator on the left side by the numerator on the right side:

5 × x = 10 × 140

5x = 1400  Divide both sides by 5 (the 5s "cancel" on the left)

5x/5 = 1400/5

x = 280

I hope this helps, especially when you see more questions like this in the future.

Answers

Answer:

19 cents

Step-by-step explanation:

Natalie buys 4 buttons at 3 cents each. She also buys 1 zipper at 7 cents

We are to find the total amount that she spends for each costume

I converted cents to dollars.

4 buttons at 3 cents = 4x0.03 (3 cents is 0.03 dollars)

= 0.12

The zipper = 7 cents = 0.07 dollars

The total amount she spent = 0.12+ 0.07

= 0.19 dollars = 19 cents

Therefore she 19 cents in total for each costume
