Which expression is equivalent to -2(-7h -
4) + 6h?

a. 20h + 8

b. 20h - 4

c. 8h + 20

d. -h + 8


​

Answer: 80

Step-by-step explanation: If he is 20% complete, then 20 x 5 is 100. So if we want to get 100%, then we have the multiply. Now he did 16 questions, so we have to multiply 16 five times. 16 x 5

22 dude everybody knows that cmon....

Step-by-step explanation:

We want to find an absolute value equation such that its solutions are 4 and 11.

We will get: |x - 7.5| = 3.5

Let's see how we can get that.

We should start by the general absolute value equation:

|x - a| = b

This can be decomposed into two equations:

x - a = b

x - a = -b

Both of these must be true, one for each of the given solutions of the equation, now we need to replace these solutions. Let's use the largest solution in the equation where b is positive.

11 -a = b

4 - a = -b

Now we have a system of equations, to solve it we can see that we have the same variable isolated in the two equations, then we can rewrite:

11 - a  = b

-(4 - a) = b

then:

11 - a = b = -(4 - a)

11 - a = -4 + a

11 + 4 = a + a

15 = 2*a

15/2 = a = 7.5

Then we can use:

11 - a = b

11 - 7.5 = b = 3.5

Now we know the values of a and b, we just need to replace them in the general equation to get:

|x - 7.5| = 3.5

This is the absolute value equation we were searching.

Answer:

Width = 12 m

Step-by-step explanation:

Width = w

Perimeter = 56 m

2*length + 2*width =  56

2* 16    + 2w  = 56

        32 + 2w = 56

               2w = 56 - 32

               2w = 24

                 w = 24/2

                 w = 12 m

Width = 12 m

Answer:

C. 124

Step-by-step explanation:

The approximate direction angle of One-half of v will be 304°. Then the correct option is D.

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

The equation of vector is given below.

v = < –10, 15 >

Then the approximate direction angle of One-half of v will be

v/2 = < –5, 7.5 >

Then the angle will be

tan θ = 7.5/(–5)

tan θ = –1.5

θ = tan⁻¹(–1.5)

θ = –56°

θ = –56° + 360°

θ = 304°

Then the correct option is D.

Answer: A rational expression is a ratio of two polynomials.

Step-by-step explanation: To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same. In other words, we must find a common denominator.

Step-by-step explanation:

to get the original slope, we need to bring the line equation to

y = ...

and the slope is the factor of x.

x + 3y = 27

3y = -x + 27

y = -1/3 x + 9

so, the original slope is -1/3.

the perpendicular slope turns this upside-down and flips the sign : 3/1 = 3.

as the slope is the ratio "y coordinate change / x coordinate change".

we can use the point-slope form for the new line equation :

y - y1 = m(x - x1)

with m being the slope, and (x1, y1) being a point on the line.

so,

y - 6 = 3(x - 1)

simplified that is

y - 6 = 3x - 3

y = 3x + 3

that is then the slope-intercept form (+3 being the interception point on the y-axis).

Answer:

y = 3x + 3

Step-by-step explanation:

The answer is simple and plain.

Answer:

Answer:

100 dollars

Step-by-step explanation:

First you multiply how much it is each month by how many months.

5x15=75

Then you add the money he has to pay to sign up. So,

75+25=100

Answer:

I believe the answer would be $100

Step-by-step explanation:

1. He already payed the $25 so he doesn't need to pay that anymore

2. If he's paying $15 a month you would have to multiply 15 by 5 because he went for 5 months

3. for the five months he payed $75, so after that you would have to add the additional $25 to the $75 get the answer of $100

3. since the scale is every 1cm is 14 miles than to find 56 miles on a map you should divide 56/14 which would equal 4cm.

4. since the scale is every 1 inch is 6 feet and you have to find how long a motorcycle is if it was 2 in on a diagram, then you should multiple 6 by 2 which would equal 12 feet

Answer:

40 members

Step-by-step explanation:

Let the total members = x

Given the following data;

Number of sixth graders = 12 members

The mathematical expression is;

[tex] \frac {30}{100} * x = 12[/tex]

[tex] 0.3x = 12[/tex]

[tex] x = \frac {12}{0.3} [/tex]

x = 40

Therefore, the total members in the middle school coding club is 40 members.
