Answer and step-by-step explanation:

5. To arrange it, find its value first:

4 - 6 = -2

-4 + 6 = 2

-4 - 6 = -10

So to arrange it from the least to greatest, it would be:

-10 , -2, 2 = c => a => b

8. To know which one have the least solution, calculate all of it first:

a. x + 5 = 13

Subtract both side by 5

x = 13 - 5

x = 8

b. -6x = -30

Divide both side by -6

-6x / -6 = -30/-6

x = 5

c. x / 4 = 18

x = 18 * 4

x = 72

d. x - 2 = -11

x = -11 + 2

x = -9

So d. have the least value (-9)

9. a. 10x - 4x = 6x

b. -15n + 3n = -12n

c. 7.5y + 1.6y = 9.1y

d. m + 4 - 2m = m - 2m + 4 = -m + 4

10. Student B are the students who invole in both piano and the band (As you can see it is in the middle of the diagram and it located in both circle (diagrams) so it would be both

Student G is the student who in the band because they only located in the band circle (diagram)

Hope those would help you :3

A party host is making identical party bags for guests using 44 bottles of bubbles, 89 stickers, and 55 pencils. What is the gre
Umnica [9.8K]

Answer: 11 party bags with 1 sticker leftover

Each bag contains 4 bubbles, 8 stickers, and 5 pencils.

<u>Step-by-step explanation:</u>

Find the GCF of 44 (bubbles), 89 (stickers), and 55 (pencils)

44: 2 x 2 x <u>11</u>

89: prime so choose 88 with 1 leftover

88: 2 x 2 x 2 x <u>11</u>

55: 5 x <u>11</u>

GCF = 11

Disregard the GCF to see how many of that item should go in each bag.

Bubbles: 2 x 2

Stickers: 2 x 2 x 2

Pencils: 5

What weight of dry substance is in 150g of a 3% substance solution? What weight of an 8% solution can we have with the same weig
Pavlova-9 [17]
The answers are: 4.5 g and 56.25 g respectively.

Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g

For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g

The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 30 , P = 1260 . Work o
Lapatulllka [165]

Answer:

875 Watts

Step-by-step explanation:

Given that :

P α s²

P = ks²

Where k is the proportionality constant

When ; p = 1260 ; s = 30

1260 = k * 30²

1260 = 900k

k = 1260 / 900

k = 1.4

Value of p ; when s = 25

P = 1.4 * s²

P = 1.4 * 25²

P = 1.4 * 625

P = 875 watt
