what expression is correct?​

Answer

b

Step-by-step explanation:

I hope this is right

The correct answer is b.) 2.78 hours

Let d represents the number of miles, Shanice is from home at time t (hours). Since she is 27.2 miles from home and she rides at an average of 9.8 miles per hour, hence:

d = 27.2 - 9.8t

At time the time she is at home, d = 0, hence to find the number of hours it takes her to ride home, we equate d = 0 and solve for t, hence:

0 = 27.2 - 9.8t

9.8t = 27.2

t = 2.78 hours

Therefore, it takes her 2.78 hours to ride home.

Given:

Angle LMN has a measure of 35°.

The angle is rotated 75° about point M to create angle L'M'N'.

To find:

The measure of angle L'M'N'.

Solution:

We have,

[tex]m\angle LMN=35^\circ[/tex]

The angle LMN is rotated 75° about point M to create angle L'M'N'.

We know that, rotation is a rigid transformation. So, after rotation the corresponding sides and angles remains congruent.

It means,

[tex]m\angle L'M'N'=m\angle LMN[/tex]

[tex]m\angle L'M'N'=35^\circ[/tex]

Therefore, the measure of angle L'M'N' is 35°.

Answer:

83

Step-by-step explanation:

x = 1st number

x+2 is the next consecutive odd number

x+ x+2 = 164

Combine like terms

2x+2 = 164

Subtract 2 from each side

2x= 162

Divide by 2

2x/2 =162/2

x = 81

x+2 = 83

The largest number is 83

The absolute value of a number is the distance the number is from 0 on a number line. Since distance is never negative, absolute value is never negative.

Answer:  x  is 9° ,  y is 21°. The measure of angle ABE is 48°.

Step-by-step explanation:

First we will solve for x.  

The variable x appears in the angle 8x + 18   and that angle is a right angle.

Right angles have the measure of 90 degrees so we will set the angle equal 90  and solve for x.

8x + 18 = 90    Subtract 18 from both sides

      - 18   -18  

8x = 72     divide both sides by 8

x = 9  

y is also on the right side and the combination of both angles has to also equal 90 degrees because they form a right angle.

Since we already know x is 9 we will input it into the left side for x and solve for y.

y + 3(9) + 2y = 90

3y + 27= 90

    -27     -27

3y = 63

 y = 21  

Now we need to find the measure of angle ABE.

ABE is represented by  y + 3x  so since we know the value of y and x we will input it into the expression and solve for the angle.

21 + 3(9) = m∠ABE

21 + 27= m∠ABE

48 = m∠ABE

This means the measure of angle ABE is 48°

Answer:

y = 2x + 3/2

Step-by-step explanation:

4x - 2y = -3

y = mx + b

-2y = -3 - 4x

y = 3/2 + 4/2x

y = 3/2 + 2x

y = 2x + 3/2

C. 5(x-6)=20

Step-by-step explanation:

we can represent the value of x decreased by 6 times 5 as 5(x-6) and then show that that is equal to 20.

Answer:  [C]:  " 5(x - 6) = 20 " .

____________________________________________

Step-by-step explanation:

____________________________________________

Five multiplied (the difference of a 'number' and 6) is "20";

 The "is" refers to an "equal sign";

Let us refer to the unknown number with the variable, "x" ;

Re:  The  "difference" of a "number and 6" ;

Note the "difference" indicates "subtraction:

So;  " (x - 6) ;

"Five times (that difference)" shall be written as:

5*(x - 6) ;

or:  5(x - 6) ;  

We are told that this value "is 20" ; that is:  "equal to 20" ;

So we can rewite the expression; as follows:

    " (5x - 6) = 20 " ;  

Which corresponds to:

   Answer choice:  [C]:  " 5(x - 6) = 20 " .

Answer:

(6, -3)

Step-by-step explanation:

You can graph the point and jump to the correct midpoint, or you can use the midpoint formula, ([tex]\frac{x1+x2}{2} , \frac{y1+y2}{2}[/tex]). Find x1, x2, y1, and y2 from (10,-5) and (2, -1).

Answer: (6,-3)

Step-by-step explanation: you need to use the midpoint formula, which is (x1+x2)/2, (y1+y2)/2. With that, you just need to put in the points correspondingly. Do (10+2)/2 which is 6, and (-5+(-1))/2 which is -3. The midpoint then is (6,-3)
