The value of the fraction 3c+2/4 one less than the value of the fraction 5c-1/3<br><br> Solve for c

kifflom [539]

Answer:

Step-by-step explanation:

The value of the fraction 3c+2/4 one less than the value of the fraction 5c-1/3 is expressed as;

(3c+2)/4 = (5c-1)/3 - 1

We are to calculate the value of c as shown;

(3c+2)/4 = (5c-1)/3 - 1

(3c+2)/4 = [(5c-1) - 3]/3

(3c+2)/4 = 5c-4/3

Cross multiply;

3(3c+2) = 4(5c-4)

9c + 6 = 20c -16

9c - 20c = -16 -6

-11c = -22

c = 22/11

c = 2

Hence the value of c is 2

Jose, baulus, and George are having a disagreement over interest rates. Jose says that 6 3/4% can be expressed as 6.75%. George

otez555 [7]

Answer:

Jose and George are correct

Baulus is incorrect

Step-by-step explanation:

Given

$6\frac{3}{4}$ %

Required

Compare the above expression with

Jose: 6.75%.

George: 0.0675

Baulus: 0.0675%

<em>The expression </em> $6\frac{3}{4}$ <em>% is given as a mixed fraction;</em>

In Jose's case, he simply converted it to decimal

Converting $6\frac{3}{4}$ % to decimal;

First, we need to convert to improper fraction

$6\frac{3}{4}$ % in improper fraction is $\frac{27}{4}$ %

Then, we divide the numerator by the denominator

$\frac{27}{4}$ % = 6.75%.

Hence, Jose is correct

In George's case, he solved further by removing the % from Jose's answer.

% means divided by 100; In other words, x% means that we divide x by 100

So, 6.75% means we divide 6.75 by 100

$\frac{6.75}{100}$ = 0.0675

Hence, George is also correct

But same can't be said of Baulus;

Baulus converted $6\frac{3}{4}$ % as 0.0675%

This means that he converted $6\frac{3}{4}$ as 0.0675 then he appended it with the percentage sign (%)

Since $6\frac{3}{4}$ is not equal to 0.0675, then we can conclude that Baulus is incorrect

To buy a truck you can pay $13,000 cash or put down $4250 and make 24 monthly payments of $595.54. How much would you save by pa

-Dominant- [34]

Savings by paying cash is $1,289.6.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

To buy a truck cash payment = $13,000

And, Put down cash = $4250

Now, Calculate the total amount with payments;

Total amount with payment = Payment amount * Total month

= $595.54 * 24

= $14,289.6

And, Calculate the total amount saved by paying cash;

Savings by paying cash = Total amount with payments - Cash payment

= $14,289.6 - $13,000

= $1,289.6

Hence, Savings by paying cash is $1,289.6.
