there are 10 less red skittles than orange Skittles in a bag. The orange Skittles are also twice the number of red skittles. Find the number of red and orange Skittles in the bag.

Answers

Answer: there are 20 orange skittles and 10 red skittles in the bag.

Explanation:

Since we have given that

Let the number of red skittles be x

Let the number of orange skittles be 2x

According to question,

[tex]2x-x=10\\x=10[/tex]

So, there are 10 red skittles in the bag and

The number of orange skittles in the bag is given by

[tex]2x=2\times 10=20[/tex]

Hence, there are 20 orange skittles and 10 red skittles in the bag.

The number of red and orange Skittles in the bag are;

I. Red skittles, R = 10

II. Orange skittles, S = 20

Let the orange skittles be denoted by S.Let the red skittles be denoted by R.

To find the number of red and orange Skittles in the bag;

Translating the word problem into a mathematical (algebraic) expression, we would have;

[tex]R = S - 10[/tex] ....equation 1.

[tex]S = 2R[/tex] ....equation 2.

Substituting eqn 2 into eqn 1, we have;

[tex]R = 2R - 10\\\\2R - R = 10[/tex]

Red skittles, R = 10

To find the number of orange skittles;

[tex]S = 2[/tex] × [tex]10[/tex]

Orange skittles, S = 20

A scuba diver is swimming 15 feet below the water’s surface. The diver swims up slowly at 0.5 feet per second for 4 seconds; and then stops to look at an eel. Finally, the diver swims up for 3 more seconds at 0.4 feet per second. What is the diver’s new depth

Answers

0.5 x 4 = 2 feet / 2 feet in 4 seconds
15 - 2 = 13
New depth: 13 feet

0.4 x 3 = 1.2 feet / 1.2 feet in 3 seconds
13 - 1.2 = 11.8
New depth: 11.8 feet

Answer: The diver's new depth is 11.8 feet below the water's surface.

Step-by-step explanation:

Since we have given that

Depth below the water's surface = 15 feet

The diver swims up slowly at 0.5 feet per second for 4 seconds.

Number of miles he swims up is given by

[tex]0.5\times 4\\\\=2\ feet[/tex]

Number of miles he swims up for 3 more seconds at 0.4 feet per second.

So, Number of miles he swims up is given by

[tex]0.4\times 3\\\\=1.2\ feet[/tex]

So, the diver's new depth would be

[tex]-15+2+1.2\\\\=-15+3.2\\\\=-11.8\ feet[/tex]

Hence, the diver's new depth is 11.8 feet below the water's surface.

The most basic figure in geometry is called a point. For example, point A which can also represent as .A. If we have a point, we usually we usually label it with a capital letter. If we have two points such as points X and Y, we can introduce our next figure in geometry which is called a line segment. For example, segment XY. A line segment is defined as a figure that is composed of two points which are called the endpoints and all the points in between. Segment XY can be represented as XY with a segment drawn over it.

Find −115+(−35) Write your answer as a fraction in simplest form.

Answers

Final answer:

To find -115 + (-35), simply add the two numbers as if they were positive, then add a negative sign, resulting in -150. It can be written as a fraction in simplest form as -150/1.

Explanation:

The operation in this question is addition. You are adding two negative numbers.

To add two negative numbers, simply add the numbers as though they were positive, then add a negative sign to the result. So, in this case, you would add 115 and 35 to get 150, then add a negative sign to your answer, resulting in -150.

This can be written as a fraction in simplest form as -150/1. It's also important to note that any number over 1 is simply the number itself, so -150/1 is essentially just -150.

Please help! Quick!

Problem:

Solve:
5z+7=32

Please SHOW ALL YOUR WORK! (P.S. please show your work clearly, because I will need it for other problems! Thanks!)

Answers

5z+7=32
5z+7-7=32-7
5z/5=25/5
z=5

5z + 7 = 32

1) You have to try to get z by itself, so that means isolating 7 and 5.

5z + 7 = 32
5z - 7 - 7
----------------
5z = 25

2) Whatever you do to one side, you do to the other. So you subtracted 7 to 7 to isolate 7, and you would subtract 7 to 32 as well. And that will leave you with 5z = 25.

3) Whenever there are a number and a variable next to it, it symbolizes multiplication. (5 x z = 5z) So in order to isolate 5z without taking away your variable, you would have to divide 5 from 5, and also 25.

5z = 25
__ ___
5 5
____________
z = 5

____________________________________________________________
So, the steps are to write the equation out.
Combine any like terms, if there is any. (Ex. 5x + 3 + 52x + 39 {you can combine 5x and 52x because they are like terms, meaning they are alike. Other words are simplifying. (57x) :)}[and you can combine 3 and 39 since they are alike too. (42)])
Then, you add/subtract ON BOTH SIDES!
And after that, you finish it off by multiplying/dividing ON BOTH SIDES.

And how you know if you subtract or add is that if it is positive or negative.
Ex. +5 ( you would subtract in order to get it to zero. So -5)
Ex. -5 ( you would add in order to get is to zero. so +5)

And how you know it's multiplication or division.
Ex. 5x (5 * x = 5x, so you would divide by 5 to get zero, and divide 5 ON BOTH SIDES)
Ex. \frac{x}{5} [/tex] ( you would have to multiply 5 from top and bottom and ON BOTH SIDES)

The table shows which school subjects are favored by a group of students. Predict the number of students out of 400 that would pick science as their favorite subject.
Subject Number Of Responses
Math 6
Science 3
English 4
History 7

Answers

First, add up all of the numbers.

6+4+7+3=20

3 out of the 20 students favour Science.

You need to find the total out of 400, so set up a proportion.

3/20 = x/400

To solve the proportion, you multiply 3 and 400 to get 1,200, then divide it by 20, which is 60.

So out of the 400 student, 60 favour Science.

60 should favor science

Which is the graph of the linear function that is represented by the equation y=1/2x-2

Answers

To do this, lets identify the slope and the y-intercept.

y = mx + b
y = -1/2x - 2

The slope is -1/2 and -2 is the intercept.

So, it is the 3rd one.

Hope this helps!

It would be the 3rd answer. Linear functions take on the equation
y = mx + b , m is the slope and b is the y intercept. That means in the equation given
m = 1/2 (slope) and b = -2 (y intercept)
The slope is rise over run or y/x so since the slope is 1/2 for every 1 unit moved up, you move 2 across. The y intercept is where the graph crosses the y axis.

Write an integer for each situation identify its opposite and describes its meaning
Question: 5 strokes above par

Answers

5
Opposite -5
Above means positive
Par=0
Integer would be positive

Final answer:

The integer representation of '5 strokes above par' is '+5', while its opposite is '-5', representing '5 strokes under par'. The positive and negative signs indicate whether you are above or below the par in golf.

Explanation:

In the context of golf, '5 strokes above par' means that it took five more strokes than the par to complete a hole or course. We can express '5 strokes above par' as the integer +5. In this context, the positive sign in front of 5 indicates you are above par, which means it took you more swings to finish.

Conversely, the opposite of +5 is -5. This would mean '5 strokes under par,' suggesting that it took five fewer strokes than the par to finish the hole or course. Note that in golf, being under par is generally better as it means you needed fewer swings to complete the course.

the greatest range....the range is ur y value, it will be the total cost...the x is gonna be the number of 1/2 hrs. And the 5 per life vest has to be multiplied by 2 because there is 2 people, making it 10

the greatest range will be when u rent the canoe for the longest.
8 a.m to 6 p.m......thats 10 hrs....20 half hrs...so the greatest range is when u rent the canoe for 20 half hrs.

Answers

You'd do plus 1 cause that the backward way then add one to seven also and you'll have 4y=8 then divide 4 to each side so y=2

4y-1=7

Basiclly, you need to add one to the other side and subtract one from the original side so there is just 4y there.

That leaves you with 4y=8

Then divide both sides by four so there is no number by y. 8/4 is 2.
y=2.
