You can make a common denominator, then multiple the top by said denominator, then cross it out - because they are the same

Answer:

x = 2 12/13

Step-by-step explanation:

(x - 4)/7 = (8 - 3x)/5

A fraction is the same as a division problem, and you can see that x-4 is being divide by 7

The opposite of dividing by 7 is multiplying by 7

Multiply both sides by 7

x-4 = (8-3x)/5 * 7

x - 4 = 56 - 21x/5

Now multiply both sides by 5

5x - 20 = 56 - 21x

Now solve:

5x - 20 = -21x + 56

26x - 20 = 56

26x = 76

x = 2 12/13

If my answer is incorrect, pls correct me!

Rewrite 4/11 and 1/3 so that they have a common denominator

valkas [14]

Remark

11 and 3 are both prime. So the common denominator is 33

$\dfrac{4}{11} = \dfrac{4*3}{11*3} = \dfrac{12}{33}$

$\dfrac{1}{3} = \dfrac{1*11}{11*3} = \dfrac{11}{33}$

13. Raj and Eric went to lunch. Raj's total lunch bill was $9.53. This was 14%

Feliz [49]

Answer:

C: $9.53*(0.86)

Step-by-step explanation:

To find Eric's lunch bill, we have to work backwards. Since Raj's bill is 14% higher, we have to make it 14% lower to get Eric's lunch bill. We can do this by multiplying the original price by 1-0.14.

$9.53*(1-0.14)=$9.53*(0.86)
