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= $\frac{3}{10}x$

What is the solution to 4+5e^x+2 =11

Nezavi [6.7K]

Answer:

x =0

Step-by-step explanation:

4+5e^x+2 =11

Combine like terms

6 + 5e^x =11

Subtract 6 from each side

6-6 + 5e^x =11-6

5 e^x = 5

Divide by 5 on each side

5 e^x /5 = 5/5

e^x = 1

Take the natural log on each side

ln (e^x) = ln(1)

x = ln(1)

x =0
