18 divide by 2 * 3/5-2 simplify show all work

Answers

Answer 1

Answer:

9

Step-by-step explanation:

I would guess it looks like this - if not then tell me

[tex] \frac{18}{ \frac{2 \times 3}{5 - 2} } [/tex]

2×3=6

5-2=3

Then there's only

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

Which is equal to

[tex] \frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9[/tex]

Answer 2

Answer:

9 or 3 2/5

Step-by-step explanation:

There are two scenarios, (5 - 2) in denominator and 5 in denominator as it is not clear. Solving both:

18/2*3/(5 - 2) =9*3/3 = 9*1 =9

------------------------

18/2*3/5 - 2 =9*3/5 - 2=27/5 - 2 =17/5 =3 2/5

Diagnostic tests of medical conditions can have several types of results. The test result can be positive or negative, whether or not a patient has the condition. A positive test (+) indicates that the patient has the condition. A negative test (−) indicates that the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 200 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.
Assume the sample is representative of the entire population. For a person selected at random, compute the following probabilities. (Enter your answers as fractions.) Test Result Test Result Column Total Condition Present 105 24 129 Condition Absent 25 46 71
(a) P(+ condition present): this is known as the sensitivity of a test.
(b) P(- | condition present); this is known as the false-negative rate.
(c) Pcondition absent); this is known as the specificity of a test.

A nutrition label says that one serving out of a bag of chips has 3.7 grams of fat. how many grams of fat are there in 2.5 servings?

Answers

Step-by-step explanation:

1 serving = 3.7g of fat

=> 2.5 servings = 3.7g * 2.5 = 9.25g of fat.

Hence there are 9.25g of fat.

Answer:

2.5 servings of chips has 9.25 grams of fat.

Step-by-step explanation:

1 serving of chips has fat = 3.7 grams

We need to find how many grams of fat are there in 2.5 servings.

So, solving using unitary method:

If we are given grams of 1 serving, so multiplying it with 2.5 will give us grams of fats of 2.5 servings.

1 serving of chips has fat = 3.7 grams

2.5 servings of chips has fat = 3.7 * 2.5

                                               = 9.25 grams

So, 2.5 servings of chips has 9.25 grams of fat.

hey um, so i’m learning ab percentages in my math class so can someone please explain to me how to solve percent problems if that’s ok? thank you.

Answers

Answer:

It's pretty simple. For example, if it says there is a percentage increase on something like there is a jacket for $25 and there was a 15% increase, you multiply 25 by 1.15 to see what the new price is. But say if the same $25 jacket is on sale for 15%, then you can multiply 25 by .15, then subtract that from 25 or originally subtract the 15% from 100 which is 85 and multiply 25x.85 and get the answer directly.

Alexis and Paige work together as photographers for the local newspaper. Alexis is paid $25 for each news story she shoots and an additional $5 per picture. Paige makes $15 for each news story and $10 per picture. Write an expression to show how much the newspaper will pay if Alexis and Paige are hired together. Use p as the variable for pictures​

Answers

Answer:

The expression 40n+15p shows the amount paid by the newspaper if Alexis and Paige are hired together.

Step-by-step explanation:

Given that:

Alexis charges $25 for each news story and $5 per picture.

Let,

n represent the number of news stories and p represent the number of pictures.

Alexis' total charges = [tex]25n+5p[/tex]

Paige charges $15 for each news story and $10 per picture.

The variables will be same.

Paige's total charges = [tex]15n+10p \\[/tex]

Alexis and Paige's charges will be added if newspaper hire them together.

Total charges paid by newspaper = [tex]25n+5p+15n+10p=40n+15p[/tex]

Hence,

The expression 40n+15p shows the amount paid by the newspaper if Alexis and Paige are hired together.

186 = 6 (3n + 7) answer for N

Answers

n=8 is the correct answer

Answer:

n = 8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

186 = 6(3n + 7)

Step 2: Solve for n

Divide 6 on both sides:                    31 = 3n + 7Isolate n term:                                   24 = 3nIsolate n:                                            8 = nRewrite:                                             n = 8

Step 3: Check

Plug in n into the original equation to verify it's a solution.

Substitute in n:                    186 = 6(3(8) + 7)Multiply:                               186 = 6(24 + 7)Add:                                     186 = 6(31)Multiply:                               186 = 186

Here we see that 186 does indeed equal 186.

∴ n = 8 is the solution to the equation.

(Please explain thoroughly step by step how you solved the problem.If you can,please provide an image of how you solved the problem.)

Answers

Answer:  8.82

Work Shown:

(5.15)/(6.30) = (7.21)/(x)

5.15*x = 6.30*7.21 ....... cross multiply

5.15x = 45.423

x = (45.423)/(5.15) ...... dividing both sides by 5.15

x = 8.82
