Quantity of paint left = $\frac{389}{480}$ gallons

Solution:

Quantity of yellow paint = $1\frac{1}{5}=\frac{6}{5}$ gallons

Quantity of green paint = $1\frac{1}{6}=\frac{7}{6}$ gallons

Quantity of blue paint = $\frac{7}{8}$ gallons

Quantity of paint used = $\frac{3}{4}$ gallons of each paint

Quantity of paint left = $1-\frac{3}{4}=\frac{1}{4}$ gallons of each paint

Quantity of paint left = $(\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}$

Taking LCM for 5, 6, 8, we get LCM = 120

$(\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}=(\frac{144}{120}+\frac{140}{120}+\frac{105}{120})\times\frac{1}{4}$

$=(\frac{389}{120})\times\frac{1}{4}$

$=\frac{389}{480}$

Hence, Mark will have $\frac{389}{480}$ gallons of paint left after painting the mural.

Simplify each expression and evaluate it for x=3 1/3, the equation is 3(2x+6)−(3x+1)

Verdich [7]

Value of the expression for x = 3 1/3 is 29.

Step-by-step explanation:

Step 1: Simplify the expression 3(2x+6)−(3x+1)

⇒ 3(2x+6)−(3x+1) = 6x + 18 - 3x + 1 = 3x + 19

Step 2: Find the value of the expression for x=3 1/3

⇒ x = 3 1/3 = 10/3

⇒ 3x + 19 = 3 × 10/3 + 19 = 29

morpeh [17]

Answer:

C. 3/5

Step-by-step explanation:

Probability that M will occur =1-0.8=0.2=1/5

Probability that R will occur = 1-0.6=0.4=2/5

Probability that either of them will occur= 1/5 + 2/5= 3/5
