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

The solution of the multiplication of the 250 x 15 will be 1250 + 2500. The correct option is D.

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

When we multiply a multiplicand by one digit of a multiplier that has more than one digit, the result is known as a partial product.

Given numbers 250 and 15. The multiplication will be done as below:-

 250

 x 15

--------

1250

2500

--------

3750

Therefore, the solution of the multiplication of the 250 x 15 will be 1250 + 2500. The correct option is D.

As OP bisects ∠AOR, ∠AOP = ∠POR = 55°

So, ∠AOR = ∠AOP + ∠POR = 55° + 55° = 110°

As OS bisects ∠ROB, ∠ROS = ∠SOB = x

As total angle on a line is 180°,

110° + x + x = 180°

=> 2x = 70

=> x = 35°

∠POS = ∠POR + ∠ROS = 55° + x = 55° + 35°

=> ∠POS = 90°

Answer:

189 gallons

Step-by-step explanation:

7 gallons for 3 classrooms, so 7/3 for 1 classroom

multiply 7/3 * 129 to get 301 gallons at North High School

multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary

301 - 112 = 189 gallons more at North High School than at Edgewater Elementary

The more gallons should be 189 gallons

7 gallons for 3 classrooms, so 7 by 3 for 1 classroom

Now  

we have to multiply 7 by 3 with 129 so that 301 gallons at North High School could come

Now  

multiply 7 by 3 with 48 to get 112 gallons at Edgewater Elementary

Now

=  301 - 112

= 189 gallons more

Answer:

  g(x) = (x +1)^2 +3

Step-by-step explanation:

You know that the transformation ...

  g(x) = f(x -h) +k

moves the f(x) graph h units to the right and k units up. In this problem, we have h=-1 (1 unit left) and k=3 (3 units up), so the transformation is ...

  g(x) = f(x +1) +3

Since f(x) = x^2, the equation for g(x) is ...

  g(x) = (x +1)^2 +3

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:

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:

Answer:

90-46=54

Step-by-step explanation:

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:

x = number of hours to train plan a clients

x = 0.55 hour

y = number of hours to train plan b clients

y = 0.87 hours

Step-by-step explanation:

Friday

Plan a = 8 clients

Plan b = 3 clients

Total hours = 7

Saturday

Plan a = 3 clients

Plan b = 5 clients

Total hours = 6

Let

x = number of hours to train plan a clients

y = number of hours to train plan b clients

8x + 3y = 7 (1)

3x + 5y = 6 (2)

Multiply (1) by 5 and (2) by (3)

40x + 15y = 35 (3)

9x + 15y = 18 (4)

Subtract (4) from (3)

40x - 9x = 35 - 18

31x = 17

Divide both sides by 31

x = 17 / 31

= 0.548 hour

Approximately

x = 0.55 hour

Substitute x = 0.55 hour into (1)

8x + 3y = 7

8(.55) + 3y = 7

4.4 + 3y = 7

3y = 7 - 4.4

3y = 2.6

Divide both sides by 3

y = 2.6 / 3

= 0.867 hours

Approximately

y = 0.87 hours

x = number of hours to train plan a clients

x = 0.55 hour

y = number of hours to train plan b clients

y = 0.87 hours

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
