Answer:

(6,2)

Step-by-step explanation:

To solve this equation using the substitution method we can plug in the given value of x into the equation, 3x+2y=22 and solve for y. Once we get the value of "y" then we can plug the y into our second equation which is x=5y-4.

3x+2y=22

plug in 5y-4 for the x value, so

3(5y-4)+2y=22    now distribute the 3 to the (5y-4) (multiply the 3 by 5y and -4)

3*5y= 15y  and 3*-4= -12,

15y-12+2y=22 ←this is our equation after distributing

we can combine the 15y and 2y because they share the same variable

(15y+2y)

17y-12=22 add 12 to both sides to eliminate the -12 and divide by 17 to get rid of the 17 next to y or isolate the y variable

17y-12+12=22+12  →  17y=34   divide both sides by 17

[tex]\frac{17y}{17} =\frac{34}{17}[/tex]      the 17's cancel and the 17 divides into 34, leaving us with

y=2

now substitute the y=2 into the equation x=5y-4

so    x=5(2)-4 →  x=10-4 → x=6

So we have the values for both our x and y values, all we need to do is put them in an ordered pair in the form (x,y)  

so the ordered pair is (6,2)

The ratio gives the number of times one value can be found in the other value.

The correct responses are;

1. The ratio is three to eight

2. The ratio in fraction form is [tex]\dfrac{12}{7}[/tex]

3. The ratio in column form is 15:9 = 5:3

II. 4. 5: 15 = 1 : 3

[tex]5. \ \displaystyle \frac{80}{100} = \frac{4}{5}[/tex]

6. 24 : 48 = 1 : 2

7. 468 students to 9 classroom = 52 student to 1 classroom

8. 54 km to 3 hours = 18 km to 1 hour

III. 9. [tex]\displaystyle \frac{3}{4}= \frac{6}{8}[/tex]

10. 20 : 8 = 5 : 2

11. 6 : 18 = 1 : 3

IV. 12 [tex]\displaystyle \frac{50}{100} = \frac{1}{2}[/tex] The correct option is c.

13. 42 out of 50 = 42 : 50

The correct option is c.

14.The ratio of girls to boys is 12:18 not 18:12

The option that DOES NOT describe the ratio is d. 18:12

15. [tex]\displaystyle \frac{45}{60} = \frac{3}{4}[/tex]

Answer: I think it’s D

Step-by-step explanation:

Answer:

The domain is a set/group of x-values. The range is a set/group of y-values. The first option is not true because there are x-values which are greater than 0 (right side of graph). The second option is not true because the set of y-value stops before it hits the y=0. The third option is not true because there are no y-values which are less than 0 (bottom of graph). The fourth option is correct because the x-values stretch from -infinity on the left side of the graph to positive infinity of the right side of the graph.

⇛-7.5(x−3) = 3.75

⇛-7.5x + 22.5 = 3.75

⇛-7.5x = 3.75 - 22.5

⇛-7.5x = -18.75

⇛x = -18.75 ÷ -7.5

⇛x = -18.75/-7.5

⇛x = 2.5

Answer:

2.5

Step-by-step explanation:

-7.5(x-3)=3.75

or, -7.5x+22.5=3.75

or, -7.5x= 3.75-22.5

or, -7.5x= -18.75

or, x= 18.75÷7.5

or, x= 2.5

65

Answer:

91.9 feet to the nearest tenth.

Step-by-step explanation:

Let the required distance be x feet.

Using the Pythagoras theorem:

x^2 = 65^2 + 65^2

x^2 = 8450

x = 91.9.

Speed = distance / time

45 minutes = 0.75 hours

1 hour and 45 minutes = 1.75 hours.

70 km / 1.75 hours = 40 km per hour

Answer: 40 km per hour

The speed of a bird with respect to the wind Bird's air speed is 2.25 mi/h. The speed of the wind with respect to the ground wind's speed is 0.75 mi/h.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Relative speed is usually given in terms of the speed of body A with respect to another body B (Vab)

Vab = Va - Vb

Vab = Speed of A relative to B

Va = Speed of A

Vb = Speed of B

So, for this question, when the bird is travelling in the same direction of the wind, the speed of the bird with respect to the ground is 3 mi/h

(Speed of bird with respect to the wind)

= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)

Speed of bird with respect to the wind = x

Speed of bird with respect to ground = 3 mi/h

Speed of the wind with respect to the ground = y

(Speed of bird with respect to the wind)

= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)

x = 3 - y

When the bird is travelling in the opposite direction, the speed of the bird with respect to the ground is 1.5 mi/h

Speed of bird with respect to the wind = x

Speed of bird with respect to ground = 1.5 mi/h

Speed of the wind with respect to the ground = -y (Negative since the wind is in the opposite direction)

(Speed of bird with respect to the wind)

= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)

x = 1.5 - (-y)

x = 1.5 + y

We can then solve this system of equations

x = 3 - y

x = 1.5 + y

1.5 + y = 3 - y

y + y = 3 - 1.5

2y = 1.5

Divide both sides by 2

(2y/2) = (1.5/2)

y = 0.75 mi/h

x = 1.5 + y

x = 1.5 + 0.75

x = 2.25 mi/h

Answer:

-8 4/5

Step-by-step explanation:

Answer:

32.48 square inches

Step-by-step explanation:

The area of a polygon is [tex]A=\frac{nsa}{2}[/tex] where [tex]n[/tex] is the number of sides of the polygon, [tex]s[/tex] is the side length of the polygon, and [tex]a[/tex] is the length of the apothem.

We are given the polygon is a heptagon, so it has 7 sides, making [tex]n=7[/tex]

We are given the heptagon's side length is 3.2 inches, making [tex]s=3.2[/tex]

We are also given an apothem of 2.9 inches, making [tex]a=2.9[/tex]

Therefore, by using the formula for the area of a polygon, we get[tex]A=\frac{nsa}{2}=\frac{7*3.2*2.9}{2}=\frac{64.96}{2}=32.48[/tex]

In conclusion, the area of the heptagon is 32.48 square inches
