Help please. Sort the numbers.

**Answer:**

1) 2² + 3² - 2 = 4 + 9 - 2 = 11

3² + 2² - 3 = 9 + 4 - 3 = 10

2) 4(3²) + 3(2) + 3 = 36 + 6 + 3 = 45

4(2²) + 3(3) + 3 = 16 + 9 + 3 = 28

3) 2(3) + 3 + 1 = 10

4) 3(2²) + 2(3) + 2 = 12 + 6 + 2 = 20

3(3²) + 2(2) + 3 = 27 + 4 + 3 = 34

5) 2⁴ - 3² + 3 = 16 - 9 + 3 = 10

6) 2³ - 2(3)(3) - 5 = 8 - 18 - 5 = -15

3³ - 2(3)(3) - 5 = 27 - 18 - 5 = 4

1) x = 3, y = 2

2) neither

3) x = 2, y = 3

-4(-6x + 4) ?

(including steps please!) :D

**Answer:**

-32

**Step-by-step explanation:**

first you need to find the unknown #(.666) and multiple it by 6 then add 4 then times 8 by for to get - 32.

**Answer:**

24x - 16

**Step-by-step explanation**

What we're doing here is **factorisation**

To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).

First,

-4 x -6x

-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.

You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that **2 negatives make a positive! **

Next,

Multipying the outside number by the second inside again:

-4 x 4 = -16

Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.

Finally,

Connect both of these answers

24x - 16 is the answer!

(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)

The Person above me is correct

A community swimming pool is a rectangular prism that is 30 feet long, 12 feet wide, and 5 feet deep. The wading pool is half as long, half as deep, and the same width as the larger pool.

How many times greater is the volume of the swimming pool than the volume of the wading pool?

Enter your answer as a number, like this: 42

HELLLLPPPP PLEASEEEEEE

**Answer:**

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

**Step-by-step explanation:**

By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:

Community swimming pool

[tex]V_{c} = l\cdot w\cdot h (1)[/tex]

Wading pool

[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)[/tex]

Where:

l – Length of the swimming pool, measured in feet.

h – Depth of the swimming pool, measured in feet.

w – Width of the swimming pool, measured in feet.

[tex]V_{c}[/tex] – Volume of the community swimming pool, measured in cubic feet.

[tex]V_{w}[/tex] – Volume of the wading swimming pool, measured in cubic feet.

The ratio of the volume of the community swimming pool to the volume of the wadling pool is:

[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)[/tex]

[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]

[tex]\frac{V_{c}}{V_{w}} = 4[/tex]

**The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.**

70x + 50 = 190

What is x?

**Answer:**

x = 2

**Step-by-step explanation:**

70x + 50 = 190

=> 70x = 140

=> x = 2

Therefore, x = 2.

Hoped this helped.

2

subtract 50 from both sides, then you’re left with 70 X equals 140, divide each side by 70 and X equals 2

subtract 50 from both sides, then you’re left with 70 X equals 140, divide each side by 70 and X equals 2

Identify the terms in the expression 70 – (4 • 15).

**Answer: 4200? or 10 because there is a minus sign**

**Step-by-step explanation:**

if we start with the parentheses you can see 4 x 15 = 60 and your subtracting 70 minus 60 so it would be 10

**Step-by-step explanation:**

Given expression:

70 – (4 • 15)It has two terms:

70 and – (4 • 15)If we need to solve it then:

70 – (4 • 15) = 70 - 60 =10Mallory puts $1.00 in a jar. The following week, she puts 2 times that original amount in the jar. For each of the next six weeks, Mallory continues to double the amout of money she places in her savings jar each week.

Determine if the relationship is linear or nonlinear. Explain your choice using examples with ordered pairs. (week, amount)

We want to see if the **relationship **between the number of weeks and the money put in the jar is **linear **or not, we will see that this is not a **linear equation **(it is **exponential**).

So a** linear relation** is something like:

y = a*x + b

Note that for any value of x, an increase of 1 unit gives:

y = a*(x+ 1) + b = (a*x + b) + a

So for increases of 1 unit in the **x-value**, we have increases of "a" units on the **y-value**.

In the given situation we have:

In week 1 she puts $1.00 in the jar.In week 2 she puts $2.00 in the jar (now the jar has $3.00 in it)In week 3 she puts $4.00 in the jar (now the jar has $7.00 on it)In week 4 she puts $8.00 in the jar (now the jar has $15.00 on it)and so on.

Writing that as **points **we have:

(1, $1)

(2, $3)

(3, $7)

(4, $15)

Notice that for equal increases in the **x-value**, (increases of 1 unit) we don't equal increases in the** y-value** (first increases by $2, then by $4, etc...) So this is not a** linear equation**, this is **actually exponential.**

If you want to learn more, you can read:

https://brainly.com/question/19770987

The **relationship **of the **ordered pair **that represents Mallory savings is a **nonlinear relationship**.

Let x represents the number of **weeks**, and y represents the **amount **put in the jar, each **week**.

So, we have the following highlights for 6 weeks.

Week 1: (1, 1)Week 2: (2,2)Week 3: (3,4)Week 4: (4,8)Week 5: (5,16)Week 6: (6,32)The **ordered pairs **can then be represented as:

[tex](x,y) = (1,1)(2,2)(3,4)(4,8)(5,16)(6,32)[/tex]

As the **x values **increase, the **y values **increase too, but the **y values **do not increase at a **constant rate**.

This means that the **relationship **is not **linear**; it is an **exponential relationship**.

Hence, the relationship is a **nonlinear relationship**.

Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed, do not want a new mall. How many people did Annette survey?

We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.

We will find that the number of people that Annette survey is 480.

To get the solution:

Let's assume that she surveyed a total of X people.

Then we can write the equivalence:

100% = X

We know that the 37.5% is equivalent to 180 people, then we can write:

37.5% = 180

The two equations are:

100% = X

37.5% = 180

Now we can take the quotient between these two equations to get:

(100%/37.5%) = X/180

Solving for X we get:

(100%/37.5%)*180 = X = 480

So the total number of people surveyed is 480.

**Answer:**

480 people

180/X × 100 = 37.5%

180 × 100 = 37.5 × X

18000 ÷ 37.5 = 37.5 × x ÷ 37.5

480 people = x
