15 + 2x + 3x - 10

Answers

Answer 1

Answer:

1.) 5x + 14 : (2x + 3x = 5x)  (5 + 9=14)

2.) 3x - 4 : (-3x + 6x = 3x)  (-4 + 2 = -4)

3.) 6x + 12 : (10x - 4x = 6x)  (2 + 10 = 12)

4.) 5x - 9 : ((11x - 9x = 2x) + 3x = 5x)  (-12 + 3 = -9)

5.) 5 + 5x (15 - 10 = 5)  (2x + 3x = 5x)

(HELP ASAP) A bag contains lettered tiles. The theoretical probability of choosing a vowel is 30%. The bag contains 42 consonants. How many tiles are in the bag?

Answers

Answer: I'm not so sure but my answer is 54 or 55

Step-by-step explanation:

The probability of choosing a vowel is 30%, and there are 42 consonants, so we would set up an equation like this:

42 times 30% (0.30) = 12.6 (rounded to 12)

So we have 12 vowel and 42 consonants in the bag, the total tiles would be:

12+42= 54

* But in case your teacher rounded up to 13 (vowels), the answer should be 55. But the probability rounded up to 13 is very low.

55 your welcome pretty sure that’s it

Given that;

F(n) = 2n – 1

And n = -1 and 7

What is function rule?

A function rule is the relationship between the dependent and independent variables in the form of an equation.

Now,

Put n = -1

F(-1) = 2(-1) – 1

        = -3

Put n = 7

F(7) = 2(7) – 1

       = 13

Hence,

The value is  F(-1) = -3 and F(7) = 14.

Marcus bought a booklet of tickets to use at the amusement park. He used 50% of the tickets on rides, 1/4 of the tickets on video games, and the rest of the tickets in the batting cage. Marcus says he used 24% of the tickets in the batting cage. Do you agree?

[Yes or no,] because the percentage benchmark for 1/4 is [BLANK] %, so he used a total of [BLANK] % on rides and games. This leaves [BLANK] % for the battling cage.

Answers

Answer:

No, 25%, 50%, 25%

Step-by-step explanation:

Find the percentage of tickets left:

50 + 25 = 75

(percents are out of 100)

100 - 75 = 25

He saids he used the rest of the tickets at the batting cage so it would be 25% not 24%

Answer:

1. 7 - (-15) = 7 + 15 = 22

2. 23 - 4 = 19

3. -15 -4 = -15 - 4 = -19

Please tell me if this is correct, your teacher seems to be adding a lot of unneeded steps for some reason, that's really annoying when they do that!

Answer:

1. 7 - (-15) = 7 + 8 = 22

2. 23 - 4 = 23 + (-4) = 19

3. -15 - 4 = -15 + (-4) = -19

Step-by-step explanation:

1.

"-( -" makes the number in the parenthesis a positive number therefore it is +

7 + 15 = 22

7 + 15 is equal to 7 + 8 which equals 22

2.

23 - 4 = 23 + ??? = 19

23 - 4 = 19

23 + 9 = 32

23 + 8 = 31

23 + 7 = 30

23 + 6 = 29

23 + 5 = 28

23 + 4 = 27

23 + 3 = 26

22 + 2 = 24

22 + 1 = 23

22 + 0 = 22

22 + (-1) = 21

...

22 + (-4) = 19

( I can't fully answer #2 because the other choices are covered but I hope this helps)

3.

-15 - 4 = -15 + (-4) = -19

-15 - 4 = -19

What is Graph?

A graph is a framework made up of a number of things, some of which are paired together to form "related" objects. The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

The link between arcs and points is described by a graph, which is a mathematical description of a network. A graph is made up of certain locations and the connecting lines. It doesn't matter how long the lines are or where the points are located. A node is the name for each element in a graph. Based on the given Graph, 10 would you expect to prefer comic books.

Therefore, the correct option is A.

A claw arcade machine contains stuffed animals and mystery boxes. There are 51 items in the machine. Winning a stuffed animal has twice as many favorable outcomes as winning a mystery box. How many of each item is in the machine?

Answers

Answer: 34 stuffed animals & 17 mystery boxes.

First off, split 51 into three parts, trying to find how much 1/3 is of 51. It equals 17.

The stuffed animals in the machine are “twice as much” of the mystery boxes, so you need to multiply 17 x 2 to find the amount of stuffed animals.

17 x 2 = 34

As for the mystery boxes, you need to multiply it by one.

17 x 1 = 17.

In summary, the answer is 34 stuffed animals and 17 mystery boxes.
