Answer:

-37- -47=-10

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = the slope

b = y-intercept.

In this problem,

m = 3/5

b = ?

So far y = 3/5x + b

Let's plug the point (-3, -1) into our slope equation.

-1 = 3/5(-3) + b

Simplify the right side.

-1 = -9/5 + b

Add 9/5 to both sides.

4/5 = b

The equation is: y = 3/5x + 4/5

Answer choice A is correct.

Answer:

Step-by-step explanation:

1. Determine the LCM of the denominators LCM=10

2. Multiply each piece of the equation by the common denominator.

3. 2x + 5 = 40

4. Subtract 5 from both sides

5. 2x = 35

6. Divide both sides by 2

7. x = 35/2

Answer:

6

Step-by-step explanation:

point D = -6

point A = 18

distance between point D and A: 18 - (-6) = 24

midpoint distance = 24/2 = 12 units away from each point

-6 + 12 = 6

18 - 12 = 6

your midpoint is at 6

Answer:

6

Step-by-step explanation:

-6 to 18 is a difference of 24. half of 24 is 12.-6 + 12 is 6 so 6 is halfway between point d and point a

Answer:

34

Step-by-step explanation:

We can solve this equation by giving Sara's number a variable.

Let it be x.

Then we solve by simply interpreting the problem step by step.

"If you subtract 14 from my number..."

x - 14

"...and multiply the different by -4..."

-4(x-14)

"...the result is -80"

-4(x-14) = -80

Now that we have our equation, we can solve for x.

1.) Use distributive property to expand.

-4x + 56 = -80

2.) Subtract 56 from both sides

-4x = -136

3.) Divide by -4

x = 34

Sara's number is 34

Using distributive property to expand, it is found that Sara's number is; 34

The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is

A(B + C) = AB + AC

This property is known by distributive law and applies to subtraction also.

We need to solve this equation by giving Sara's number a variable.

Let the Sara's number a variable be x.

Then we solve by simply interpreting "If you subtract 14 from my number..." means

x - 14

Then "...and multiply the different by -4..." means -4(x-14)

"...the result is -80"

-4(x-14) = -80

Now that we have our equation,

1.) Use distributive property to expand;

-4x + 56 = -80

Subtract 56 from both sides;

-4x = -136

Now Divide by -4

x = 34

Hence, Sara's number is; 34

Answer:

answer is 160

Step-by-step explanation:

1. We assume, that the number 40 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 40, so we can write it down as 100%=40.

4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.

5. Now we have two simple equations:

1) 100%=40

2) x%=64

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=40/64

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64 is what percent of 40

100%/x%=40/64

(100/x)*x=(40/64)*x    

100=0.625*x

100/0.625=x

160=x

x=160

now we have:

64 is 40% 160

Step-by-step explanation:

The mean number of days employee were sick is 4.43 days.

Option C is correct.

Here,

Given that;

The department manager recorded the number of sick days taken last year by each employee, as shown in the table.

We have to find the mean number of days employee were sick.

What is Mean?

The average of the given numbers is called Mean and is calculated by dividing the sum of given numbers by the total number of numbers.

Now,

In given table;

Number of sick days are,

7, 4, 2, 6, 4, 5, 3

Hence,

Mean number of days employee were sick = [tex]\frac{7+4+2+6+4+5+3}{7}[/tex] [tex]= \frac{31}{7}[/tex][tex]= 4.4285[/tex]

Now, Rounding the number to the nearest hundredth we get;

Mean of number of days employee were sick = 4.43 days

Hence, The mean number of days employee were sick is 4.43 days.

Option C is correct.

answer is one solution

$9.70 / 2.5lbs = $3.88 / pound of roasted peanuts.

$8.55 * 1.4lbs = $11.97 / 1.4 pounds of almonds

$8.55 - $3.88 = $4.67.

Roasted peanuts cost $4.67 less per pound than almonds.

$11.97 - $9.70 = $2.27

You spend $2.27 more on almonds than you do roasted peanuts.

63.75 + 45 = 108.75.

Answer:108.75

The total dollar amount of coloured pencils sold is $108.75.

Given that, a craft store sells boxes of two different varieties of coloured pencils. The table shows the number of boxes sold last month.

We need to find what is the total dollar amount of coloured pencils sold.

A tally table is a table that represents the occurrence of an event in a way that calculates it becomes easy.

Now, the cost of each pencil is $4.25.

Then the cost of 15 pencils=15×4.25=$63.75

The cost of each pencil is $3.75.

Then the cost of 12 pencils=12×3.75=$45

Total=63.75+45=$108.75

Therefore, the total dollar amount of coloured pencils sold is $108.75.
