3(x - 5) = 30
I dont know how to solve this

Answers

Answer 1

Answer:

x=15

Step-by-step explanation:

3(x-5)=30

First, you would distribute the three to the x and the negative five.

3x-15=30

Then you would add 15 to the 15 to cancel it and to the 30 to make it even.

3x-15=30

  +15=+15=

3x=45

Finally, you would divide 3 into both sides, cancelling out the three and fiving you,

x=15

Hope this helped!

Answer 2

Start by distributing the 3 through the parenthses on the left side.

This gives us 3x - 15 = 30.

Now add 15 to both sides to end up with 3x = 45.

Dividing both sides by 3, we fin that x = 15.

Explain how you can use absolute value to tell whether
the sum of two integers is positive or negative.

Answers

Answer:

Let the integers are p and q.

In case both integers are positive or negative, you add the numbers up and apply their sign to the sum.

Examples:

10 + 88 = 98-20 + (-15) = -35

In case one of the integers is negative and one positive.

p < 0, q > 0

Use absolute value in this case.

Subtract the numbers and apply the sign of the number with the greater absolute value.

Examples:

- 10 + 15 = |15 - 10| = |5| = 5- 15 + 10 = - |15 - 10| = - |5| = -5

Step-by-step explanation:

Let the numbers be x and y

If both are of same signs then

|x + y| = x + y

-|x + y| = -(x + y) = -x - y

If one is negative and one is positive

-|x + (-y)| = -|x - y| = -x + y

-|y + (-x)| = -|y - x| = -y + x

The Coal Utility Company is burning coal to produce electricity. The following cost function illustrates the cost in dollars (C) of removing t% of the hazardous toxins generated from burning coal. What happens to the cost as t approaches 100?
C= 55,000t/100-t for 0 ≤ t < 100

A The cost continues to increase.
B The cost continues to decrease.
C The cost approaches $0.
D The cost approaches $55,000.

Answers

Answer:

the cost continues to increase

Step-by-step explanation:

the cost (C) approaches infinity (or becomes very large) as t approaches 100%. Thus, the correct answer is: A. The cost continues to increase.

To determine what happens to the cost (C) as t approaches 100%, we can take the limit of the cost function as t approaches 100.

The cost function is given as: [tex]\[ C = \frac{55,000t}{100 - t} \][/tex]

Now, let's find the limit of C as t approaches 100:[tex]\[ \lim_{{t \to 100}} C = \lim_{{t \to 100}} \frac{55,000t}{100 - t} \][/tex]

To find this limit, we can use direct substitution:[tex]\[ \lim_{{t \to 100}} \frac{55,000 \times 100}{100 - 100} = \lim_{{t \to 100}} \frac{5,500,000}{0} \][/tex]

Since the denominator approaches 0 as t approaches 100, the limit is undefined (infinite).

Therefore, the cost (C) approaches infinity (or becomes very large) as t approaches 100%. Thus, the correct answer is: A. The cost continues to increase.

The slot size limit for Fish A is from 28 to 32 inches. The minimum size limit for Fish B is 11 inches. Write the ranges of Fish A and Fish B in interval notation and in set-builder notation. Does the range for the Fish B seem reasonable? Explain.

Answers

Notations are used to specify the range of a function. The range of fish A is [28,32] while the range of fish B is [11,infinity).

Also, the range of fish B is not reasonable.

For fish A, we have:

[tex]Minimum = 28[/tex]

[tex]Maximum = 32[/tex]

For Fish B, we have:

[tex]Minimum = 11[/tex]

For fish A, the minimum and the maximum are inclusive. So, the range is:

[tex]Range= [Minimum, Maximum][/tex]

This gives:

[tex]A = [28,32][/tex]

For fish B, the minimum is known (and inclusive). The maximum is not known, so we represent the maximum with infinity.

So, the range is:

[tex]Range= [Minimum, Maximum)[/tex]

[tex]B = [11,\infty)[/tex]

The range of fish B is not reasonable because there is a limit to the size of fish a slot can take.

2 = 2.27 - m/4

I am so bad at math, lol! ^^ HELP ME PWEASE!

Answers

Answer:

m = 1.08

Step-by-step explanation:

Subtract 2.27 from both sides.

2 - 2.27 = -m/4

Simplify  2 - 2.27 to  -0.27.

-0.27 = -m/4

Multiply both sides by 4

-0.27 × 4 = -m

Simplify  -0.27 × 4 to -1.08.

-1.08 = -m

Multiply both sides by -1 (-m is also known as -1)

1.08 =m

Answer:

m = 1.08

Step-by-step explanation:

Basically, we can start off by finding the difference between 2 and 2.27(which is 0.27). Then we can see that 0.27 is equal to m/4. Since 0.27*4=1.08, we can see that m=1.08.
