Answer:

-4x-36

Step-by-step explanation:

multiply -4 by x

multiply -4 by 9 and add each together

Answer:

-4x + -36

Step-by-step explanation:

This problem uses the distributive property. You need to multiply -4 by both things in the parentheses.

-4 · x = -4x.

-4 · 9 = -36

Answer:

2

Step-by-step explanation:

14 divided by 7 is two customers in one minute

Answer:

After one minute there will be 2 people inside the store.

Step-by-step explanation:

First we put this into a proportion. Aka set up like a fraction.

14 (customers)                 x

-------                 --->         ------

7 (minute)                      1 minute

In order to find x, we must divide by 7  because in order to make the bottom number one on the bottom, you must divide by 7 , so we do the same to the top.

14/7 is 2.  

This means that per minute, there are 2 people inside the store.

After one minute, There will be 2 people inside the store.

Answer:

100 pounds

Step-by-step explanation:

To find their average weight, add all of their weights together then divide it by 3

(100 + 120 + 80) / 3

300 / 3

= 100

So, their average weight is 100 pounds

Answer:

(1,9)

Step-by-step explanation:

Step 1: Understand what the question is asking you

Assuming the question is asking you to solve for the point of interesection of the linear system

Step 2: Solve

Equate the 2 linear equations to each other and solve for'x'

8x + 1 = 6x + 3

8x - 6x = 3 - 1

2x = 2

[tex]\frac{2x}{2} =\frac{2}{2}[/tex]

x = 1

Sub x = 1 into any of the 2 equation for y

y=8(1)+1

y=8 + 1

y=9

Step 3: Therefore Statement

Therefore the answer to the linear system is (1,9)

The point of intersection for the two equations is (x=1, y=9).

To find the point where the two equations intersect, we can set them equal to each other since they both represent "y." So, we have:

8x + 1 = 6x + 3

Now, let's solve for "x":

8x - 6x = 3 - 1

2x = 2

x = 2/2

x = 1

Now that we have the value of "x," we can find the corresponding value of "y" by substituting "x = 1" into either equation. Let's use the second equation:

y = 6x + 3

y = 6(1) + 3

y = 6 + 3

y = 9

So, the point of intersection for the two equations is (x=1, y=9).

Answer:

[tex]3x-10<5\\x<5[/tex]

Step-by-step explanation:

Let x be equal to the number.

We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:

[tex]3x-10<5[/tex]

To find the range of possible values, we must solve the inequality and isolate x.

[tex]3x-10<5[/tex]

Add 10 to both sides

[tex]3x-10+10<5+10\\3x<15[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}<\frac{15}{3}\\x<5[/tex]

Answer:

k = 0.16

Step-by-step explanation:

First, use distributive property on the left side:

[tex]0.2(k+2.4)=3.2k\\0.2k+0.48=3.2k\\0.48 = 3k\\k = 0.16[/tex]

Answer:

k = 0.16

Step-by-step explanation:

Use distributive property, meaning individually multiply 0.2 to each number/variable within the parameters

0.2 × k = 0.2k

0.2 × 2.4 = 0.48

0.2k + 0.48 = 3.2k

You cannot add a number and a variable so instead we should isolate the variable

Subtract 0.2k from both sides

0.48 = 3.2k - 0.2k

0.48 = 3.0k

0.48 = 3k

Divide both sides by 3

0.16 = k

Answer:

5/8 bags

Step-by-step explanation:

Pepper ha 7.5 bags

These bags are needed to clear 12 yards squared equally

Therefore the number of bags required for each square yard can be calculated as follows

= 7.5/12

= 0.625

0.625 to fraction is 5/8

Hence 5/8 bags is needed for each square yard

Answer:

The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree
