3(4−7)=27
How do I solve this

Answer:

A. 1,112

Step-by-step explanation:

The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's start by finding the profit per chair:

So,

Profit per chair = Selling price - Production cost

= $55.75 - $16.91

= $38.84

Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:

Profit = Profit per chair x Number of chairs sold - Overhead costs

$24,850 = $38.84x - $18,340

$43,190 = $38.84x

x = 1,112.49

Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Therefore,

The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Answer:

Subtracting a number is the same as adding the opposite of the number

Step-by-step explanation:

Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

Taking the readings from the graph

Rate of change for the given line is:

Equation for the line is:

For the point (40, 76) we can verify with the equation:

The point (40, 76) is close the line but the line doesn't pass through it.

Answer:

x | y

0 | 2

2 | 6

4 | 10

6 | 14

Equation of the line is

[tex] \frac{y - 2}{x - 0} = \frac{6 - 2}{2 - 0} \\ \frac{y - 2}{x} = \frac{4}{2} = 2 \\ y - 2 = 2x \\ y - 2x = 2\\ \boxed{y=2x+2}[/tex]

When x=40, y will be (2×40)+2 =82

So the point should pass through (40,82) and not (40,76).

Answer:

B = no solution

Step-by-step explanation:

y = -5x - 3

-5x - y - 3 = 0

Substitute

-5x - (-5x - 3) - 3 = 0

Distributive Property

-5x + 5x + 3 - 3 = 0

Combine Like terms

0 + 3 - 3 = 0

0 + 0 = 0

0 = 0

This system has no solutions. You don't have a value for x or y

Answer:

Lauren will get $640 and Cara will get $560.

Step-by-step explanation:

Given that:

Age of Lauren = 16

Age of Cara = 14

Ratio = 16 : 14

Amount given by their grandad = $1200

Let,

x be the number of times.

16x + 14x = 1200

30x = 1200

Dividing both sides by 30

[tex]\frac{30x}{30}=\frac{1200}{30}\\x=40[/tex]

Share of Lauren = 16x = 16*40 = $640

Share of Cara = 14x = 14*40 = $560

Hence,

Lauren will get $640 and Cara will get $560.

Answer:

Step-by-step explanation:

AD║FJ and CH is transversal

∡BCH and ∡CHJ are alternate interior angles

Alternate interior angles are congruent:

Answer:

CD = 10$

Cassette = 1$

Step-by-step explanation:

ok, time to use some variables

C = CD

S = Cassette

2c + 5s = 25$

1c + 15s = 25$

the second equation has 1 less CD and 10 more Cassettes, therefore 1c = 10s

Now we can calculate how many Cassettes we can buy

1c - 1c = 0c

15s + 10s = 25s

This means that 25s = 25$

therefore 1s = 1$

since we know that 10s = 1c, and 1s = 1$, then we can figure out how many dollars the CD is

1c = 10s = 10$

1c = 10$

Answer:

Step-by-step explanation:

Step-by-step explanation:

Hey there!

Given;

The sum of two numbers is 45.

One of them is 27.

Let next number is "x".

So, Add "x" and "27" and show it is equal to 45.

Or, x+27 = 45

Therefore, x+27 = 45 is the required equation.

Now, solving unknown number.

~ Take "27" to right side and subtract it.

x= 45 - 27

X= 18

Therefore, next number is (x) = 18.

Answer:

12 and 5 inches since squaring them would equal 144+25, which is 169, and ✓169=13. the two legs have to equal the hypotenuse when combined to be a right triangle.

Answer: CB = 7.    AC = 5.

Step-by-step explanation:

Well we know that A-B is 7. And this is a right triangle, so the CB will be the same length. So CB = 7.

Now AC.

You divide 45 degrees by 7. And you get five.

So AC = 5 and CB = 7.

Answer:

AC= 7√6/2

CB=7√2/2

Step-by-step explanation:

Answer:

(8, 0)

Step-by-step explanation:

TAKE NOTE: In a glide reflection, you always start w/ the second transformation.

RULE (in this case): (x, y) --> (y, x)

(2, 7) => (7, 2)

RULE: (x, y) --> (x + horizontal shift, y + vertical shift)

(7, 2) => (7+1, 2-2) or (8, 0)

You can check your answer by doing this the opposite way.
