Identify the model that shows 4 items being divided equally among 3 people. How much will each person have

Answers

Answer:

1 1/3 items

Step-by-step explanation:

Total number of items = 4 items

Total number of people = 3 people

4 items = 3 people

To know the number of items each person will get, we can write;

x items = 1 person

Divide both expressions

4/x = 3/1

3x = 4

x = 4/3

Express as mixed fraction;

4/3 = 1 1/3

Hence each person will receive 1 1/3 items

1. 4x = -36
2. 5x - 15 = 50
3. 4(x + 2) - 17 = 35
4. 6x + 12 = 4x - 18
5. 1/2 (4x - 10) + 5 = x - 11

Answers

Step-by-step explanation:

1Ans: 4x = -36

× = -36/4

× = -9

2Ans: 5x -15 = 50

5x = 50 + 15

5x = 65

x = 65/5

x = 13

3Ans: 4(x + 2) -17 = 35

4x +8 -17 = 35

4x -9 = 35

4x = 35 +9

4x = 44

x = 44/4

x = 11

4Ans: 6x +12 = 4x -18

6x -4x = -18 -12

+2x = -30

x = -30/+2

x = -15

5Ans: 1/2 (4x -10) +5 = x -11

0.5 (4x -10) +5 = x -11

2x -5 +5 = x -11

2x = x -11

2x - x = -11

1x = -11

x = -11/1

x = -11

If 7x−6y=2 and −2x−y=3 are true equations, what would be the value of 5x−7y?

Answers

Answer:

-55

Step-by-step explanation:

7x-6y=2

-2x-y=3

by substitution method

y=3+2x

7x-6(3+2x)=2

7x-18-12x=2

-5x=20

x=-4

-2(-4)-y=3

8-y=3

-y=3-8

y=5

therefore the value of x=4 and that of y=5

5x-7y=5(-4)-7(5)

=-20-35

=-55

Keenan measured a community college and made a scale drawing. The scale of the drawing
was 1 centimeter : 9 meters. If the actual width of a building at the college is 90 meters, how
wide is the building in the drawing?

Answers

Answer:

The answer is 10 centimeters

Step-by-step explanation:

If 1 cm on the map = 9 meters. 10cm would be 90 meters. Hope this helps!

Answer:

drawing = 10 cm for the width.

Step-by-step explanation:

1 cm / 9 m = x / 90 m

If the meters go on the bottom in the left ratio, they must go on the bottom on the right ratio. In this case the cm is the unknown and it must go on the top with no units.

Cross multliply

9 m * x = 90m * 1cm        

Divide by 9

9m * x/ 9m = 90 m * 1 cm / 9m       Notice the units (m) cancel out

x = 10 cm

Railroad mileage increased in the West, reducing the effect of the settlement on American Indians True False Steelcase has received orders of 2400, 2200, 2700, and 2500 units of a special-purpose panel for each of the next four months. SC can meet these demands by producing the panel, by drawing from its inventory, or by using any combination of the two alternatives. The production costs during each of the next four months are projected to be $74, $75, $76, and $76.5 per unit. Because costs are rising each month, SC might be better off producing more panel than it needs in a given month and storing the excess. Production capacity, though, cannot exceed 4000 units in any one month. The monthly production is finished at the end of the month at which time the demand is met. Any remaining panel is then stored in inventory at a cost of $1.2 per panel for each month that it remains there. If production level is increased from one month to the next, then the company incurs a cost of $0.5 per unit of increased production to cover the additional labor and/or overtime. Each unit of decreased production incurs a cost of $0.3 to cover the benefits of unused employees. The production level during the previous month was 1800 units, and the beginning inventory is 1000 units. Inventory at the end of the fourth month must be at least 1500 units to cover anticipated demand.
