I need help.. 7k/8-3/4-5k/16=3/8

seven "k" over eight minus three fourths minus five "k" over sixteen equals three eighths

Answers

Answer 1
Answer: This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.

7k/8 - 3/4 - 5k/16 = 3/8

3/4 is the same as 6/8.
Add it to each side of the equation:

7k/8         - 5k/16 = 9/8

Multiply each side by 16 :

14k - 5k = 18

Add up the 'k's on the left side:

9k = 18

From this point, you can proceed directly to the numerical value of 'k'
if you need it.

In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help.  Nobody actually needs the answer.
Answer 2
Answer: since 16 is their least common multiple you can get rid of all of the fractions by multiplying each fraction by 16:

16(7k/8)-16(3/4)-16(5k/16)=16(3/8)
 
14k-12-5k=6
            9k=6+12
            9k=18
              k=18/9
              k=2

An integer is any whole number, including zero. This means that it cannot be a fraction or a decimal.

Therefore, the whole numbers, or integers, between -0.6 and 4.17 are:
0, 1, 2, 3, and 4

The total cost C (in dollars) to participate in a ski club is given by the literal equation C=85x+60, where x is the number of ski trips you take.a. Solve the equation for x.

b. How many ski trips do you take if you spend a total of $315? $485?

Answers

Answer:

a. x = (C — 60) / 85

bi. 3

bii. 5

Step-by-step explanation:

a. C = 85x + 60

C — 60 = 85x

x = (C — 60) / 85

bi. When C = $315,

x = (C — 60) / 85

x = (315 — 60) / 85

x = 225/ 85

x = 3

bii. When C = $485

x = (C — 60) / 85

x = (485 — 60) / 85

x = 425/ 85

x = 5

IN a survey, 10% of the people said they live in a city. If 60 people said they live in a city, how many people were surveyed? Please show all work

Answers


You said:  " 10% of the people = 60 people "

' 10% ' means 0.1
' of ' means ' times '

So                                 (0.1) x (the people) =  60 people

Multiply each side by 10 :          the people = 600 people
