Which expression has a value that is equal to the given expression when n = 8? 2n + 10 A. 3n
B. 10n + 2
C. n² + 5
D. 2(n+5)

Answers

Answer 1

Answer:

D.

Step-by-step explanation:

2n + 10

When n = 8 we have

2*8 + 10

= 16 + 10

= 26.

When n = 8:

2(n + 5)

= 2(8 + 5)

= 2*13

= 26.

So it's D.

Answer 2

Answer:

D. 2(n+5)

Step-by-step explanation:

The answer is A! If 1/3 is gone, there’s 2/3 left. To find how much 2/3 is, you would multiply 80 by 2/3

8x + 3 (3 - x) = 34
A. x = 5
B. x = 2
C. x = 8
D. x = 4

Answers

Answer:

A. x=5

Step-by-step explanation:

8x+3(3-x)=34

We move all terms to the left:

8x+3(3-x)-(34)=0

We add all the numbers together, and all the variables

8x+3(-1x+3)-34=0

We multiply parentheses

8x-3x+9-34=0

We add all the numbers together, and all the variables

5x-25=0

We move all terms containing x to the left, all other terms to the right

5x=25

x=25/5

x=5

I think this is correct.

Answer: its A; x=5

Step-by-step explanation:

8x+3(3-x)=34

distribute the 3 through the parentheses

8x+9-3x=34

then add the like terms

5x+9=34

subtract the 9 to the 34

you shoud get

5x=25

then divide the 5 on both sides and you get your answer of x=5

Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=(f(2x)/2) + 2. What is the sum of coordinates of that point?

Answers

Answer:

Step-by-step explanation:

jjjjj

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function

The sum of the coordinates of the point is 7.25

The reason the above values are correct is as follows;

The given parameter is;

The point (9, 7) is on the graph y = f(x)

Required:

A point on the graph, 2·y = (f(2·x)/2) + 2

Solution:

Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;

f(2·x) = f(2 × 9/2) = f(9) = 7

Therefore;

2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5

y = 5.5/2 = 2.75

y = 2.75

The coordinate of the point is (x, y) = (2.75, 9/2)

The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?

Answers

Answer:

4 wooden and 3 plastic

Step-by-step explanation:

4 (wooden) × 2 - 5 = 3 plastic

3 (plastic) + 4 (wooden) = 7 total

The number of plastic frames is 4 and the number of wooden frames is 3.

What is equation?

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given statement:

The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.

The total number of frames sold by Tristan is 7.

Write the equation for the above statement,

p = 2w - 5

Here, p is a plastic frame and w is a wooden frame,

p + w = 7

Solve the equation by using the elimination method,

p = 4 and w = 3

Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?

Answers

Answer:

I think the answer is 171.

Step-by-step explanation:

Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)
