Answer:

6.25

Step-by-step explanation:

Divide 150 $ to 24 caps on your calculator

If the cost of 24 caps is $150, then the cost of each cap is $6.25.

We know that a single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method. We typically use this technique for math calculations. We are able to locate the missing value using the unitary method.

Given that the cost of 24 caps is $150.

Then the cost of 1 cap is 150/24 = $6.25

Therefore we can conclude that If the cost of 24 caps is $150, then the cost of each cap is $6.25.

Answer:

18=2m-4

Step-by-step explanation:

18 is the age of John. M represents the age of Michael. John is older than Michael so instead of 18=4-2m it is 18=2m-4. If you do 8=4-2m it will be inccorect because it will give you a negative. Michael is 11 years old.

Step-by-step explanation:

y-b=m(x-a)

y--8=1/4(x-6)

y+8=1/4(x-6)

4y+32=1(x-6)

4y+32=x-6

4y=x-38

y=1/4x-38/4

or -x+4y+38=0

or -×+4y= -38

Answer:

Terell gained 5 and 1/6 pounds between March and June

Step-by-step explanation:

1. 109 - 104 = 5

2. Convert 1/3

1/3 = 2/6

3. Convert 1/2

1/2 = 3/6

4. Subtract them

3/6 - 2/6 = 1/6

(Full equation: 109 and 1/2 - 104 and 1/3 = 5 and 1/6 pounds)

The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let y represent the total money the salesman earns for selling a total of $x sales. Hence:

y = 0.085x + 3750

If the salesman makes a total of $138000, hence:

y = 0.085(138000) + 3750

y = 15480

The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.

Answer:

Step-by-step explanation:

Slope intercept form

[tex]y= mx + c[/tex]

m=slope

c= intercept

1)  y= -x + 6      

2) y=7x + 6

3) y= -3/4x + + 3

4) y= -2/5x - 1/5

5) y= -x + 20

6) y= -7x + 8

7) y= -3x + 3

8) y= -2/5x -2    

Line 1 and 5 are parallel because both have the same slope of -1

line 4 and 8 are also parallel as the their slopes are -2/5

Answer:

so the answer is 30

now to find the answer we just need to do this...

step 1: we need to simplify the equations from both sides.

[tex]\frac{-2}{5} x = -12[/tex]

then we multiply on both sides by [tex]\frac{5}{-2}[/tex]

[tex](\frac{5}{-2}) *(\frac{-2}{5}x )= (\frac{5}{-2} )*(-12)[/tex]

which equals x= 30

Step-by-step explanation:

Step-by-step explanation:

Answer:

x = [tex]\frac{2}{5}[/tex], x = 4

Step-by-step explanation:

Given

5x² - 22x + 8 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 5 × 8 = + 40 and sum = - 22

The factors are - 20 and - 2

Use these factors to split the x- term

5x² - 20x - 2x + 8 = 0 ( factor the first/second and third/fourth terms )

5x(x - 4) - 2(x - 4) = 0 ← factor out (x - 4) from each term

(x - 4)(5x - 2) = 0

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]

Answer:

34.25 seconds

Step-by-step explanation:

Given that :

Summation of the complete lap time of each of the four swimmers = 137.009 seconds

The average lap time for each of the four swimmers will be :

The average of the total lap time ;

Total lap time / number of swimmers

= 137.009 / 4

= 34.25225 seconds

Hence, each swimmer has an average lap time of 34.25 seconds

The solution of the system of equations will be (2, 8).

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The system of equations are,

y = 4x

And, y = 3x + 2

Now,

Solve the linear equations as;

The system of equations are,

y = 4x      .... (i)

y = 3x + 2   .. (ii)

Substitute y = 4x in equation (ii) as;

y = 3x + 2

4x = 3x + 2

4x - 3x = 2

x = 2

And, y = 4x

y = 4 × 2

y = 8

Thus, The solution of the system of equations will be (2, 8).
