11/24+w=11/12 I need help​
DaniilM [7]

Answer:

w = 11/24

Step-by-step explanation:

11/24 + w = 11/12

w = 11/12 - 11/24

LCM of 12 and 24 is = 24

divide the denominators of both fractions by the LCM(24) and then multiply the results with the numerators

so we have w = 22 - 11 /24

w = 11/24

Answer:

2  2/3

Step-by-step explanation:

-2 1/3 - ( - 5)

5 - 2 1/3

Borr from the 5

4 3/3 - 2 1/3

2 2/3

The sign of the larger was positive so the answer is positive

If you add 21 to my number and then multiply the result by 3, you will get 84 more than two-thirds of my number. Find my number.
Ksivusya [100]

Based on the calculations, the unknown number is equal to \frac{-45}{7}

  • Let the unknown number be x.

<h3>How to find an unknown number:</h3>

Translate the word problem into an algebraic expression, we have;

Adding 21 to the unknown number:

21 +x

Multiplying the result by 3:

3\times (21+x)

84 more than two-thirds of the unknown number:

\frac{2x}{3} +84

Equating the equations, we have:

3\times (21+x) = \frac{2x}{3} +84\\\\43+3x=\frac{2x}{3} +84

Cross-multiplying, we have:

43+3x=\frac{2x}{3} +84\\\\129+9x=2x+84\\\\9x-2x=84-129\\\\7x=-45\\\\x=\frac{-45}{7}
