someone help me please

Answer:

$280

Step-by-step explanation:

Step one

Given data

A mechanic makes $350 /week

20% of his income is deducted for taxes

Required

the mechanic's take-home pay for the week

Step two:

let us find 20% of $350

=20/100*350

= 0.2*350

=$70

Therefore the take-home pay is

= 350-70

= $280

Step-by-step explanation:

Answer:

6/25

Step-by-step explanation:

2 1/2 = 5/2

3/5 / 5/2 = 3/5 * 2/5 = 6/25

f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.

So in this problem, we're putting a 2 into our function which

means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.

So f(2) = 7 or the value of the function at 2 equals 7.

[tex]f(x) = 3x + 4[/tex]

[tex]f(2) = 3(2) + 4 \\ f(2) = 6 + 4 \\ f(2) = 10[/tex]

Therefore the value of f(2) is 10.

f(a) means the value of f(x) is ... at x = a. Same goes to the f(2) = 10. It means the value of f(x) = 10 at x = 2.

[tex]f(2) = 10[/tex]

Answer:

60x8 480 -5 475 divided by 2 is 237.5

Step-by-step explanation:

Answer: 0.234375

Step-by-step explanation:

Conversion a mixed number 2 2/

3

to a improper fraction: 2 2/3 = 2 2/

3

= 2 · 3 + 2/

3

= 6 + 2/

3

= 8/

3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/

3

= 6/

3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Divide: 5/

8

: 8/

3

= 5/

8

· 3/

8

= 5 · 3/

8 · 8

= 15/

64

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/

3

is 3/

8

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - five eighths divided by eight thirds = fifteen sixty-fourths.

Answer:

1,400 students

Step-by-step explanation:

Calculation for how many actually enroll

First step is to calculate the numbers of students that was accepted

Numbers of students accepted=10,000 students*40%

Numbers of students accepted=4,000 students

Now let calculate the numbers of students that was enrolled

Students enrolled=4,000 students*35%

Students enrolled=1,400 students

Therefore the numbers of students that actually enrolled is 1,400 students

Answer:

try = (-10/11)x - (49/11)

Answer:

Step-by-step explanation:

Given the system of equations:

2t + w = 10 ..... 1

4t = 20 − 2w ... 2

From 1:

w = 10-2t ...3

Substitute 3 into 2 to have;

4t = 20 - 2(10-2t)

4t = 20-20+4t

4t = 4t

Let t = k

Substitute t = k into 1 and get w;

From 1: 2t + w = 10

2k + w =10

w = 10 - 2k

k can take any integers. This shows that the solution to the equation is infinite

Answer:

Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0

Step-by-step explanation:

We need to solve the expression: [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]

Solving the expression:

We will use simple maths rules to solve the expression

[tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]

Subtracting 1/2 on both sides and simplify

[tex]x+\frac{1}{2}-x-\frac{1}{2}=\frac{1}{2}-\frac{1}{2}\\x-x=0\\0=0[/tex]

Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0

So, the expression is true for all values of x. there will be infinite solutions to the system.

Answer: $15

The original price of the mirror is unknown, so let's call it x.

The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.

We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.

0.2x = 3

Divide both sides by 0.2.

x = 3/0.2

x = 15

The regular price is $15.

Answer:

500 students

Step-by-step explanation:

In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?

Let the number of students enrolled at the high school be represented as x

Hence:

25% of x = 125

25/100 × x = 125

25x /100 = 125

Cross Multiply

25x = 125 × 100

x = 125× 100/25

x = 500 students

Answer:

Lin 1.454 h

Noah 1.54h

Step-by-step explanation:

From the above, we were given that;

Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour

Speed of Lin

V = [(2 3/4)/(2/5)] mph

V = [(11/4)/(2/5)] mph

V = 6.875mph

Speed of Noah

V = [(8 2/3)/(4/3)] mph

V = [26/3)/(4/3))] mph

V = 6.5mph

The time taken by Lin to cover 10 miles

t = 10/6.875

t = 1.454h

The time taken by Noah to cover 10 miles

t = 10/6.5

t = 1.54h

Answer:

2x - 3y + 8

Step-by-step explanation:

If you combine like terms

(In this case "y" and "-4y")

You get "-3y"

The rest of the equation stays the same, as there are no more like terms.

Therefore the answer is the D.

Answer:

The slope of this line is 4/1 or just 4.

Step-by-step explanation:

In order to get from one red dot to the other, you go up 4 and over 1. The entire line's formula is y=4x-2

Answer:

Undefined

Step-by-step explanation:

The graph shows a vertical line. All vertical lines have a undefined slope.

This is because that while using the slope formula you will end of with the denominator being 0. You cannot divide by zero.

[tex]\frac{6}{5}[/tex]

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~

(3, 3)

( - 2, - 3)

m = [tex]\frac{-3-3}{-2-3}[/tex] = [tex]\frac{6}{5}[/tex]
