Simplify the algebraic expression by combining like terms.

Answers

Answer:

The answer for the first problem is 10x + 4 and the answer for the second problem is 14x + 6.

Step-by-step explanation:

First problem: 6x - 3 + x + 7 + 3x

First, look at the terms, match the x's with x's and numbers with numbers.

6x + 3x + 1x = 10x

-3 + 7 = 4

So this makes the answer 10x + 4.

Second problem: 2(7x + 3)

All you need to do is distribute the 2 for 7x + 3, meaning that you multiply each of them by 2.

2 times 7x = 14x

2 times 3 = 6

So the answer is 14x + 6.

What is the value of x

Answers

Answer:

X = 56 degrees

Step-by-step explanation:

Angles D and F are equivalent. Because the three angles must add up to 180 degrees, you must add 112 to 68 in order to reach 180. Then you must divide this in half, getting 56 degrees as your answer.

180 - 68 = 112

112/2 = 56

X=56

Damian is buying a video game that was just marked 20% off. The original price was
$80. What is the new price of the video game?

Answers

Answer: $64

80(0.20) = 16
80 - 16 = 64

Since it’s a discount, after we multiplied it with 20% (0.20), we need to take the product and subtract it from the original price.

russell works at a football concession stand selling drinks for $2 and bags of chips for $3

Answers

Answer:

its 5

Step-by-step explanation:

2+3 = 5

-_-

The number of drinks sold by Russell were 54 and number of chip sold were 46.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Russel sells a total of 100 drinks and bags of chips

C+D=100...(1)

Drinks for $2 and bags of chips for $3.Russell makes a total of $246

3C+2D=$246..(2)

Let us solve above two equations to find the number of drinks and chips sold.

C=100-D (From (1))...(3)

Substitute  (3) in (2)

3(100-D)+2D=246

300-3D+2D=246

300-D=246

300-246=D

D=54

Now plug D value in equation (1)

C+54=100

Subtract 54 from both sides

C=100-54

C=46

Hence the number of drinks sold by Russell were 54 and number of chip sold were 46.

2) 90 < x < 180: Obtuse angle.

3) 90 > x : Acute angle.

4) 180 < x < 360 :  Reflex angle.

Given,

Category of angles.

Now,

1)

Right angle : An angle of exactly 90 degrees.

x = 90 degrees

2)

Obtuse angle :

An angle between 90 degrees and 180 degrees.

90 < x < 180

3)

Acute angle:

An angle less than 90 degrees.

90 > x

4)

A logarithmic function of base ‘3’ has a vertical asymptote at the line x=1. Its graph contains the point (2,1). What is the equation of the function?
1) f(x)=log3 (x+1)
2) f(x)=log3(x-1)+1
3) f(x)=log3(x+1)+1
4) f(x)=log3(x)+1

Answers

9514 1404 393

Answer:

  2)  f(x) = log3(x -1) +1

Step-by-step explanation:

The vertical asymptote of the log function is normally x=0. In this function, it is moved to the right 1 unit. That is accomplished by replacing the function argument x with (x-1). Only one answer choice matches:

  f(x) = log3(x -1) +1

Carmen is writing an article for a magazine. She will be paid a flat fee and also will be paid for each word that is published. The total amount she can expect to be paid, in dollars, can be estimated using the function f(x) = 2.5x + 150 . where s is the number of words published . What is the inverse of this function?

Answers

Step-by-step explanation:

Given Function

f(x) = 2.5x + 150

f^-1(x) = ?

Let y = f(x)

y = 2.5x + 150

Interchanging the role of x and y we get,

x = 2.5y + 150

x - 150 = 2.5y

y = (x - 150) / 2.5

So therefore

f^ -1(x) = (x - 150) / 2.5

Chef Rita is cooking for a Sunday brunch. She knows that 22 pancakes can feed 8 people. She is wondering how many people (p) she can feed with 55 pancakes. She assumes each person eats the same quantity of pancakes.

Answers

Answer:

20 people

Step-by-step explanation:

In order to find out how many people she can feed with 55 pancakes, we must find out how many pancakes she can feed 1 person.

22/8 = 2.75

She can feed 2.75 pancakes to one person.

55/2.75 = 20

Therefore, she can feed 20 people with 55 pancakes.
