The inequality as per the given statement will be equal to 3 < x < 7.

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the information in the question,

Let the number is x.

x is less than 7.

x < 7 and,

x is greater than 3,

So, x > 3

So, it can be written in combined form as:

3 < x < 7

Answer:13.D      14.C

Step-by-step explanation:

1/5

5/12

Hi there !

1/2 × 2/5 = 1×2/2×5 = 2⁽²/10 = 1/5

3/4 × 5/9 = 3×5/4×9 = 15⁽³/36 = 5/12

Good luck !

Answer:

1/5

5/12

Step-by-step explanation:

These are the answers because:

1) Whenever we multiply fractions, we have to multiply the numerator with the numerator and the denominator with the denominator.

2) In this case it would be:

1/2 x 2/5 = 1 x 2/2 x 5 = 2/10 = 1/5

3/4 x 5/9 = 3 x 5/4 x 9 = 15/36 = 5/12

Hope this helps! :D

Answer:

C. work backwards

Step-by-step explanation:

Given from the first statement of the question that that four people are in line. This is the result of the question, so the strategy required would be the work backwards.

Jennifer is ahead of Jeanie implies that Jeanie is somewhere behind Jennifer.  Since John is neither the first or the last in the line, then he must be between Jeanie and Jennifer. And Jarett is directly in front of Jennifer, so that Jarett is the first in line. The arrangement goes thus:

                   Jeanie ⇒ John ⇒ Jennifer ⇒ Jarett

Answer:

The answer is C, work backwards.

Answer:

11 am

Step-by-step explanation:

Bus A and Bus B leave the bus depot at 9 am.

Bus A takes 30 minutes to complete its route once

Bus B takes 40 minutes to complete its route once.

We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route

30 = 3 × 10

40 = 4 × 10

= 3 × 4 × 10

= 120 minutes

120 minutes after 9 am is

60 minutes = 1 hour

60 minutes = 1 hour

= 2 hours.

9am + 2 hours

= 11 am.

Therefore, they be back at the bus depot together at 11 am

Answer:

Patel found an incorrect quotient and checked his work using multiplication incorrectly.

Step-by-step explanation:

After completing the fraction division 8 divided by StartFraction 1 Over 6 EndFraction, Patel used the multiplication below to check his work.

Correct calculation

8 ÷ 1/6

= 8 × 6/1

= 48

Check:

1/6 * 48

= 48 / 6

= 8

Patel's calculation

1/48 * 6

= 1/48 * 6/1

= 6/48

= 1/8

Patel found an incorrect quotient and checked his work using multiplication incorrectly.

The boutique's monthly sales when Jenny first began tracking the data is 4000

A function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain (a sub-domain).

Given:

According to given function we can say that there x represent the number of month.

So, if jenny begin tracking the data then jenny spend 0 month on working

Thus, we will use the function

f(x)= 4000*(1.1)^x

f(x)= 4000*(1.1)^0

f(x)= 4000

Answer:

The perimeter of a quadrilateral will be equal to the addition of the length of each side of the quadrilateral.

Here we only have the vertices of the quadrilateral, and to calculate the length of the sides, first we need to plot the points in a graph and see which pairs make the quadrilateral.

You can see the image below, where i did a rough sketch of the problem.

in the image, you can see that the sides of this rectangle are the ones formed by the pairs:

(-4,3) and (-2, 8)

(-2, 8) and (2, 5)

(2,5 ) and (1, -7)

(1, - 7) and (-4, 3)

Now let's calculate the length of each side.

Remember that when we have two points (a, b) and (c, d) the distance is:

D = √( (a - c)^2 + (b - d)^2)

Now we need to calculate four distances:

(-4,3) and (-2, 8)

D1 = √( (-4  + 2)^2 + (3 - 8)^2) = 5.39

(-2, 8) and (2, 5)

D2 = √( (-2  - 2)^2 + (8 - 5)^2) = 5

(2,5 ) and (1, -7)

D3 = √( (2  - 1)^2 + (5 + 7)^2) = 12.04

(1, - 7) and (-4, 3)

D4 = √( (1  +4)^2 + (-7 -3)^2) = 11.18

Now we add those four distances to get the perimeter:

P =  5.39 + 5 + 12.04 +  11.18 = 33.61

And we want to round it to the next whole number, because the first digit after the decimal point is larger than 5, we round up, and get:

p = 37

In (4, 1) 4 represents x, and 1 represents y

y = 3x + 1

1 = 3(4)+1

1 = 12 + 1

1 ≠ 13   ← sides are not equal so (4, 1) is not a solution to y=3x+1

Hiiiii.

Answer:

ASA Postulate

Step-by-step explanation:

It's Angle-Side-Angle Postulate because you can see two clearly congruent angles, two clearly congruent sides attached to that angle, and the angle connected to that line is congruent to the other triangles corresponding angle because they're vertical angles.

Answer:

B. ASA

Step-by-step explanation:

We know that the angles in which the triangles are connected are equal to one another because the lines continue and do not bend so that is your first angle, then we see a red line on both triangles indicating that the sides are equal. That is your side, and finally there is a red curve in both corners of the triangle indicating the angles are equal. Therefore the triangle is congruent by ASA.

To check if the answer is right or wrong, you can add 1 7/12 to 4 11/12

4 11/12 + 1 7/12 = 5 18/12 = 6 6/12 = 6 1/2

Answer:

33 cups of sugar should be used

Step-by-step explanation:

subtract 12 from 21 then add that answer to 24 and you get 33 so 33 cups of sugar should be used

42 cups of sugar should be used if 21 cups of flour are used

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

For a given recipe, 12 cups of flour are mixed with 24 cups of sugar

We need to find cups of sugar should be used if 21 cups of flour are used

Let us consider x as cups  of sugar should be used if 21 cups of flour are used

Let us form an equation to find x

12/24=21/x

Apply cross multiplication

12x=21×24

12x=504

Divide both sides by 12

x=504/12

x=42

Hence, 42 cups of sugar should be used if 21 cups of flour are used

Answer:

no solutions

Step-by-step explanation:

Given

4x + 2(x - 5) = 3(2x - 4) ← distribute parenthesis on both sides

4x + 2x - 10 = 6x - 12

6x - 10 = 6x - 12 ( add 10 to both sides )

6x = 6x - 2 ( subtract 6x from both sides )

0 = - 2 ← not possible

This indicates the equation has no solution
