Answer:

(15,23)

Step-by-step explanation:

-4x+3y=9

5x-2y=29

Let's multiply the first equation by 2 and the second equation by 3, in order to have the same coefficient on y.

-8x+6y=18

15x-6y=87

Add these two equations together to eliminate y.

7x=105

x=15

Now, plug in x, to find y.

5(15)-2y=29

75-2y=29

-2y=-46

y=23

Answer:

21.4 feets

Step-by-step explanation:

Using Pythagoras rule :

The length of the string:

Hypotenus = sqrt(opposite² + adjacent²)

Length of string = sqrt(17² + 13²)

Length = sqrt(289 + 169)

Length of string = sqrt(458)

Length of string = 21.400

Length = 21.4 feets

Answer:

4.5. inches

Step-by-step explanation:

Given that:

Thickness of first book = 2 1/4 inches

Thickness of second book = same as first = 2 1/4 Inches

Stacking both books together, height of stack will be :

2 1/4 inches * 2

Height of stack = 9/4 * 2

Height of stack = 18 /4 = 4.5 inches

Answer:

[tex]y^{-5}[/tex]

Step-by-step explanation:

The Exponent Quotient Rule states that if two terms of the same base are being divided by each other, then the simplified expression is the base to the first power subtracted by the second power. As an algebraic equation, that would be [tex]\frac{x^{a} }{x^{b} } =x^{a-b[/tex], where [tex]x[/tex] is the common base and [tex]a[/tex] and [tex]b[/tex] are the exponents.

In this case, [tex]x=y[/tex], [tex]a=2[/tex], and [tex]b=7[/tex], so we know that [tex]\frac{y^{2} }{y^{7} } =y^{2-7}=y^{-5}[/tex]. Hope this helps!

Answer:

To sum up, we solved for W. Finally, the sale price of a sweatshirt was 20$.

Step-by-step explanation:

So we have our main equation of W/G=p. The G stands for the total amount which is 30. The W is the unknown in this case. As for the p equals 2/3.

Thus we substitute G and p into the equation W/30=2/3. We multiply both sides of the equation with 30 W=2*30/3. Which gives us 60/3=20.

Answer:

44°

Step-by-step explanation:

8x - 4 = 6x + 8 (This is because they are corresponding angles)

8x - 6x = 8 + 4

2x = 12

x = 12 ÷ 2

x = 6

6x + 8 = angle 1 (Vertically opposite angles are equal)

Substitute the value of x in the equation '6x +8' to get the size of the angle.

6 × 6 + 8

36 + 8 = 44°

Angle 1  =  44°

Answer:

Volume of the Catelyn's bedroom =  [tex]1173\frac{1}{4}[/tex] cubic feet

Step-by-step explanation:

Floor of Catelyn's bedroom has area = [tex]123\frac{1}{2}[/tex] square feet

                                                              = 123.5 square feet

Height of the walls = [tex]9\frac{1}{2}[/tex] feet

                               = 9.5 feet

Shape of the room is like a rectangular prism.

Therefore, volume of the bedroom = Area of the rectangular base × Height

                                                           = 123.5 × 9.5

                                                          = 1173.25

                                                          = [tex]1173\frac{1}{4}[/tex] cubic feet

Complete question :

At a farm, four employees harvest 48 pounds of food over a certain numbers of hours. Each employee works the numbered of hours shown. Employee A: 6 hours employee B: 4 hours employee C: 6 hours employee D: 8 hours The number of pounds of food harvested by each employee is proportional to the number of hours worked. Fill in the table with the amount of food, in pounds, each employee harvested.

Answer:

A = 12 lbs ;

B = 8 lbs

C = 12 lbs

D = 16 lbs

Step-by-step explanation:

Total hours worked :

(A + B + C + D)

(6 + 4 + 6 + 8) hours = 24 hours

Total pounds of food = 48 pounds

Pounds harvested per hour = 48 pounds / 24 hours = 2 pounds per hour

Amount of food harvested by each employee :

A = 6 * 2 = 12 pounds

B = 4 * 2 = 8 pounds

C = 6 * 2 = 12 pounds

D = 8 * 2 = 16 pounds
