There are 3 students to 1 adult on a field trip. You need to find the number of adults needed for 24 students. What would the second ratio of the proportion look like if the first proportion is as follows?

Answer:

x = 4.125 or [tex]4\frac{1}{8}[/tex]

y = -0.875 or [tex]-\frac{7}{8}[/tex]

Step-by-step explanation:

5x + 3y = 18

3x - 3y = 15

3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.

8x = 33

x = 4.125

Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.

3(4.125) - 3y = 15

12.375 - 3y = 15

-3y = 2.625

y = -0.875

Now we know what y is.  I hope this helps :)

Answer:

The slope is 2/1

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First thing you should notice first is that the line is going up to the left, that means that the slope will be negetave. Then, follow the rise over run method. Start at any point on the line, im going to use (0,1). go up 2 and over 1. You get -2/1 aka -2. I hope this helps!

Answer:

ok is that a question or not but if it is i may be help u

Answer:What About y = mx + b ? You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis.

Answer:

1.2*10^-2

Step-by-step explanation:

-3^0 is 1, because anything to the power of 0 (except for 0) is always equal to 1. 1 is an integer, so this is not the answer.

18/3=6, and 6 is an integer, so this is not the answer either.

1.2*10^-2 = 1.2*0.01 = 0.012, which is not an integer, so this is the answer.

49 is an integer, so this is not the answer:

Therefore, the answer to this problem is 1.2*10^-2

Hope this helped!

Answer:

[tex]1.2*(10-2)[/tex] cannot be written as an integer.

Explanation:

Fractions and decimals are not integers. All whole numbers and natural numbers are integers.

You can immediately identify that [tex]1.2*(10-2)[/tex]  cannot be written as an integer because the decimal is 1.2 and the only way it could become an integer is if it was multiplied by a number ending in 5 or with 5 as a factor (5,1 0, 15, 20, and so on). Also, it has a decimal point that isn't being multiplied by another decimal/fraction. In some cases, decimals or fractions multiplied by each other can equal an integer, but it's that's not the case in this instance.

However, if you couldn't identify this or you needed to check you answer, you could solve the expressions:

[tex]1.2*(10-2)\\1.2*(8)\\9.6[/tex]

9.6 is a decimal, therefore it is not an integer.

[tex]-3 + 0 = -3\\-3*0= 0[/tex]

I don't know if you were attempting to add or multiply, but in both cases, the sum and product equal an integer.

[tex]\frac{18}{3} = 6[/tex]

18 is divisible by 3, so you can assume that the quotient will be an integer. (3*6 = 18, to check your answer)

(To know if something is divisible by three, add the numbers of the dividend. If they equal a number that can be divided by three, you can assume that you'll get an integer and whole number.

For example: 1 + 8 = 9, 3*3 = 9)

[tex]\sqrt{49} =7[/tex]

The square root of 49 is 7. If you've memorized your square roots, you could identify quickly that the square root would be an integer. If you haven't it's okay, keep working on it!

I hope this helps!

Answer:  x/ 8 < -2           and x< -16

Step-by-step explanation:

A numer x is divided by 8  is the same as   x/ 8   and x/8 has to be the less than  -2  so it will be    x/8 < -2  

x/8 < -2   TO solve the inequality, multiply 8 on both sides  to get

x < -16

The solution of expression is,

⇒ x < - 16

We have to given that,

An algebraic expression is,

''a number x divided by 8 is less than -2''

We can write as,

⇒ x / 8 < - 2

Solve for x,

⇒ x/8 < - 2

Multiply by 8;

⇒ x < - 2×8

⇒ x < - 16

Therefore, The solution of expression is,

⇒ x < - 16

Step-by-step explanation:

Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

Answer: Multiplying both sides of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.

Then you have 3(p/3) = 3(12)

p = 36 simplify

To check this work, you can substitute 36 for p:

36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

The first thing we must observe is that the hourly rate for each candle is:

scented candles:

(1/12) / (20/60)

Simplifying:

= (1/12) / (10/30)

= (1/12) / (5/15)

= (1/12) / (1/3)

= (3/12)

= (1/4) inches / hour

Unscented candles:

(1/6) / (30/60)

Simplifying:

= (1/6) / (15/30)

= (1/6) / (3/6)

= (1/6) / (1/2)

= (2/6)

= (1/3) inches / hour
