The seventh grade class is putting on a variety show to raise money. It cost $700 to rent the

Nataly_w [17]

Well, you would need to compensate for the cost of the banquet hall adding an addition $700 to the goal of $1000.

If you need to raise at least $1700 you can write this inequality.

Let x represent the number of tickets sold.

15x≥1700

x≥ 114 (rounded to the nearest whole number because you can't sell half a ticket)

So, at least 114 tickets need to be sold.

A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area o

Ksenya-84 [330]

Answer:

The area the sprinkler sprays with water is 201.06 square feet.

Step-by-step explanation:

Step 1; It is given that the diameter of the circular area of grass that the sprinkler sprays with water is 16 feet. The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.

Radius of the circle = Diameter of the circle / 2 = 16 feet / 2 = 8 feet.

Step 2; The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.

Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet.

Solve each equation and match them with the correct solution. Column A 1. \large -3x=42 : \large -3x=42 2. \large \frac{x}{-6}=-

ella [17]

Answer:

The answer is below

Step-by-step explanation:

1) -3x = 42

Divide both sides by -3

-3x/ -3 = 42 / -3

x = -14

Answer: p.x=-14

$\frac{x}{-6}=-9\\ \\Multiply\ both\ sides\ by\ -6\\\\\frac{x}{-6}*-6=-9*-6\\\\x=54$

Answer: j. x=54

3) 5x = 105

Divide both sides by 5

5x/ 5 = 105 / 5

x = 21

Answer: n. x=-21

4) x+37=-25

add -37 to both sides

x+37 - 37 =-25 - 37

x = -62

Answer: d. x=-62

5) x-42=-15

add 42 to both sides

x-42 + 42 =-15 + 42

x = 27

Answer: k. x=27

6)x - (-12) = -4

x + 12 = -4

add -12 to both sides:

x + 12 - 12 = -4 - 12

x = -16

Answer: f. x = -16

7) x - (-6) = 5

x + 6 = 5

add -6 to both sides:

x + 6 - 6 = 5 - 6

x = -1

Answer: r. x = -1

8)8-x = -12

8 - x + x + 12 = -12 + x = 12

x = 8 + 12

x = 20

Answer: c) x = 20

9) -9 - x = -6

x = -9 + 6

x = -3

Answer: s. x =-3

10) -6 + x = 17

x = 17 + 6

x = 23

Answer: a. x =23

11)

$\frac{x}{9} =-42\\multiply\ by \ 9\\\\x = 9*-42=-378$

Answer: b. x = -378

12) -16 = x - 8

x = -16 + 8

x = -8

Answer: q. x = -8

13) -25 = x + 17

x = -25 - 17

x = -42

Answer: h. x = -42

14) 36 = 8 - x

x = 8 - 36

x = -28

Answer: g. x = -28

15) -x + 6 = 11

x = 6 - 11

x = -5

Answer: m. x = -5

16) -x + 8 = 4

x= 8 - 4

x = 4

Answer: e. x =4

17) 16 = 4 -x

x = 4 - 16

x = -12

Answer: o: x = -12

18) 85 = -5x

x = 85/ -5

x = -17

Answer: l. x= -17

19) 21 = -x/7

x = 21 * -7

x = -147

Answer: i. x = -147
