Answer:

x =29.6

Step-by-step explanation:

Let x be the number

x+20

2(x+20) = 99.2

Divide each side by 2

x+20 = 99.2/2

x+20 = 49.6

Subtract 20

x = 49.6-20

x =29.6

Answer:

4x - 43

Step-by-step explanation:

7x - 28 - 3x - 15

7x - 3x - 28 - 15

4x - 43

The simplified expression is 4x - 43.

The correct option is A.

A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.

As per the information provided, it is given that,

7(x - 4) - 3(x + 5)

Expanding the brackets and simplifying, we get:

7(x - 4) - 3(x + 5)  = 7x - 28 - 3x - 15

7(x - 4) - 3(x + 5)  = 4x - 43

Therefore, the expression is 4x - 43.

Answer:

40 inches long

Step-by-step explanation:

In order to find the shortest possible track that they can both have but still be equal in length, we need to find the least common multiple of their train track pieces. In order to do so, we simply write out the multiplication table of each of their pieces' length until we find a common number, like so

8*1 = 8                  20*1 = 20

8*2 = 16                20*2 = 40

8*3 = 24

8*4 = 32

8*5 = 40

Now we have found the first common multiple which is a value of 40 meaning that the shortest train track that they can build with the same length would be a track that is 40 inches long

Hope this helped :)

Answer:

First using y = Mx + b with m = slope and b = y intercept so 1/3 = slope and (0,6) is y intercept next plot (0,6) the plot slope from that point with rise/run or from point (0,6) go up +1 point and over +3 and make a point then go up +1 and over +3 or from (0,6) use slope = -1/-3 since they equal the same thing. So from point (0,6) go down -1 and to the left -3. Then draw your line.

<HDF

<BDG (i think)

<CDE

Step-by-step explanation:

The angles that are adjacent and congruent to ∠ BDC​ are ∠ HDF , ∠EDH and ∠CDE.

A figure is given in the question.

We have to tell about angles which are congruent to ∠ BDC.

What are the adjacent angles ?

The two angles are said to be adjacent angles when they share the common vertex and side.

As per the definition of adjacent angles ;

we can check for the adjacent angles from the figure.

Here ;

∠ BDC =  ∠ HDF.

∠ BDC =  ∠ EDH.

∠ BDC = ∠ CDE.

To check , if these are congruent too ; we must know that two angles are congruent when they have the same angle measurement, i.e., they’re equal.

if we compare from the figure ; we found that these angles are also congruent to each other.

Thus , the angles that are adjacent and congruent to ∠ BDC​ are ∠HDF , ∠EDH and ∠CDE.

He buys the same game for both brothers and pays $2.75 to ship each game, how much can he spend on each game without spending more than $100.

We need to solve the inequality for this situation.

Let he spent $x on each of the video game. ATQ,

[tex]2x+2\times 2.75\le 100\\\\2x+5.5\le 100\\\\2x\le 100-5.5\\\\2x\le 94.5\\\\x\le \$47.25[/tex]

So, he can spend less than or equal to $47.25 on each game.

Answers:

None of the five lines are horizontal or vertical

===============================================

Explanation:

Something like f(x) = 2x-5 is the same as y = 2x-5. This is because y = f(x).

Compare y = 2x-5 with y = mx+b. We see that m = 2 is the slope in this case.

The other four questions are handled the same way.

A horizontal line occurs when the slope is 0. Since none of the slopes are zero, none of the lines are horizontal.

A vertical line equation is of the form x = k, where k is any real number. The y variable is not involved. It is not possible to write a vertical line equation in the form y = mx+b because the slope m is undefined. So none of the given five equations are vertical lines.

Side note: something like y = x+6 is the same as y = 1x+6

Answer:

C) 145 degrees

Step-by-step explanation:

angles 2 and 5 are same side interior angles, which means they're supplementary. (they add together to make 180)

using that, you can make the following equation:

(x is angle 2 to avoid confusion)

35 + x = 180

subtract 35 from both sides

x = 180 - 35

x = 145

Answer:

Step-by-step explanation:

For correct questions

1 correct questions = 1 3/4 points

1 correct question = 7/4 points

Since he got 58correct questions, tgw total points he earned will be;

58 × 7/4

= 406/4

= 101.5points

For incorrect questions

1 incorrect question = -14points

22 incorrect = -14×22

22incorreft = -308points

Total points gained/lost =-308+101.5

Total points lost = -206.5

Since Nevan has a negative point of -206.5, this means that he lost.

He scored -206.5points
