Candy selling at $6.00 per pound will be mixed with candy selling at $9.00 per pound. How many pounds of the more expensive cand
Vladimir79 [104]
Given:
x = candy selling at 6 per pound
y = candy selling at 9 per pound

x + y = 15

6x + 9y = 15(7)
6x + 9y = 105

x = 15 - y

6(15-y) + 9y = 105
90 - 6y + 9y = 105
3y = 105 - 90
3y = 15
3y/3 = 15/3
y = 5

There should be 5 pounds of more expensive candy.

x = 15 - y
x = 15 - 5
x =10

There should be 10 pounds of less expensive candy.

There are some people in a cinema.
Elan Coil [88]

Answer:

Adults = 510

Step-by-step explanation:

Given

Children = \frac{3}{5}

Girls:Boys = 2 : 7

Girls = 170

Required

Determine the number of adults

First, we need to calculate the number of children

Girls:Boys = 2 : 7

Given that: Girls = 170

Substitute 170 for Girls in Girls:Boys = 2 : 7

170 : Boys = 2 : 7

Convert to fraction

\frac{170}{Boys} = \frac{2}{7}

Cross Multiply

Boys * 2 = 170 * 7

Divide both sides by 2

Boys = \frac{170 * 7}{2}

Boys = \frac{1190}{2}

Boys = 595

So, the number of children are:

Children = Boys + Girls

Children = 595 + 170

Children = 765

Next, we calculate the number of people in the cinema.

Children = \frac{3}{5} * People

Substitute 765 for Children

765 = \frac{3}{5} * People

Make People the subject.

People = \frac{765 * 5}{3}

People = \frac{3825}{3}

People = 1275

If 3/5 are children, then 2/5 are adults.

So:

Adults = \frac{2}{5} * 1275

Adults = \frac{2* 1275}{5}

Adults = \frac{2550}{5}

Adults = 510

When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number. why?
Viktor [21]
Well if you get back to the definition of a division, diving X by Y is finding out how many Ys you can have in a X.

It is clear that you will have more than X times Y if Y is less than 1 since dividing X by 1 is exactly X.

If you think of 10 and 1, you can divide 10 in exactly 10 portions of 1.
But you can divide it into 100 portions of 0,1.
And 100 is bigger than 10 of course.
Hope this helps.
