Answer:

(x,y)= (5,1)

Step-by-step explanation:

4x+2y=22

3x-2y=13

2y=22-4x

3x-2y=13

3x-(22-4x)=13

x=5

3·5-2y=13

y=1

(x,y)= (5,1)

Answer:

(5, 1); x = 5 and y = 1.

Step-by-step explanation:

Step 1: Add the system of equations

4x + 2y = 22

3x - 2y = 13

-----------------------------

7x = 35

Step 2: Solve for x

x = 5

Step 3: Substitute the value of x in one of the original equations

4(5) + 2y = 22

Step 4: Solve for y

20 + 2y = 22

2y = 2

y = 1

Step 5: Write your answer as an ordered pair

(5, 1)

15, Yes: a^2 +b^2 = c^2
9^2+12^2= 225
The square root of 225 is 15, therefore x=15.

If r=8 and s=3, find the value of rs+2s.

Sholpan [36]

Answer: 30

Step-by-step explanation:

rs + 2s when r = 8 and s = 3

8(3) + 2(3)

8 * 3 = 24

Find the volume of each figure

pshichka [43]

Answer:

See explanation

Step-by-step explanation:

1. The first figure shows triangular prism. The volume of the triangular prism is

$V=\text{Base area}\times \text{Height}$

The base of this triangular prism is the triangle with the base of 7 cm and height of $h$ cm (it is not seen).

The base area is

$\text{Base area}=\dfrac{1}{2}\times \text{Base}\times \text{Height}=\dfrac{1}{2}\times 7\times h=\dfrac{7h}{2}\ cm^2$

and the volume of the prism is

$V=\dfrac{7h}{2}\times 13=\dfrac{91h}{2}\ cm^3$

Just substitute the length of the height and calculate the volume.

2. The second figure shows square pyramid. The volume of the square pyramid is

$V=\dfrac{1}{3}\times \text{Base area}\times \text{Height}$

The base of this square pyramid is the square with the side length of 4 yd.

The base area is

$\text{Base area}= \text{Side Lenght}^2=4^2 =16\ yd^2$

and the volume of the pyramid is

$V=\dfrac{1}{3}\times 16\times 12=64\ yd^3$
