Solve for R<br><br> 3 r + 4 <br> ---------- = 5 <br> 2<br><br> r = ?

lakkis [162]

To find r, first write out the equation:
$\frac{3r+4}{2} =5$
Next, multiply both sides by 2:
$3r+4=10$
Now, subtract both sides by 4:
$3r = 6$
Divide both sides by 3:
$r=2$

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!

Brent created a mural, 4/5 of which he painted in shades of blue. Three eighths of the blue area is sky blue. What portion of th

Snezhnost [94]

Answer: $\frac{3}{10}$ of the mural is sky blue.

Step-by-step explanation:

Let x be the full portion of mural.

Since, $\frac{4}{5}$ of mural is painted in shades of blue.

Therefore, the blue portion= $\frac{4}{5}x$

Also, Three eighths of the blue area is sky blue.

Therefore, the portion of the mural is sky blue= $\frac{3}{8}\times\frac{4}{5}x$

The portion of the mural is sky blue= $\frac{12}{40}x$

Simplify, by dividing numerator and denominator by 4, we get

The portion of the mural is sky blue= $\frac{3}{10}x$
