At a concert 2/5 of the people were men, there were 3 times as many women as children. If there were 45 more men than children,

Bogdan [553]

This involves creating some equations.

First, these are what the letters I used stand for:

c = children

w = women

m = men

x = total population

Then, we must make an equation for each statement.

2/5x = m (2/5 of the people are men)

3c = w (there are 3 times as many women than children)

45+c = m (there are 45 more men than children)

Now, let's start plugging in our numbers:

x = all the men, women, and children

2/5(m+w+c) = m

2/5 (45+c +3c + c) = m [Now simplify]

2/5 (45 + 5x) = m [Now Distribute]

2/5(45) + (2/5)(5x) = m

2c + 18 = m [Above we stated that there were the same amount as men as c +45]

2c + 18 = 45 +c [Now set equal to c]

2c (-c) +18 = 45 +c (-c)

c+18 (-18) = 45 (-18)

c = 27

Now that we know that there was 27 children, we can plug 27 in for c in the other equations.

MEN = 27 + 45

WOMEN = 3(27)

CHILDREN = 27

Now add those three answers to find your total!

A mural of Elvis Presley takes 56 days to complete by seven painters 28 volunteers join the team after the first six days how ma

denpristay [2]

Answer:

10 days

Step-by-step explanation:

We are given that

Each person takes 56 days

7 painters take time= $56\times 7=392$ painter days

In first 6 days , 7 painters take time= $7\times 6=42$ painter days

After 6 days , 28 volunteers are added then,

Total persons=28+7=35

Now, remaining days=392-42=350

Therefore, number of days are required before the painting of the king of rock 'n' roll is completed= $\frac{350}{35}=10$ days

Hence,10 more days are required before the painting of the king of rock 'n' roll is completed
