Answer:
a = 4, b = - 
Step-by-step explanation:
Given
= a + b
( multiply both sides by 2 to clear the fraction )
8 - 3 = 2a + 2b
For the 2 sides to be equal , then
2a = 8 ( divide both sides by 2 )
a = 4
and
2b = - 3 ( divide both sides by - 2 )
b = -
The total number of adult tickets sold is 250.
<h3>What is the total number of adults tickets sold?
</h3>
- Let the initial number of adult's ticket sold be represented with x
- Let the initial number of children's ticket sold be represented with y
x / y = 2/5
Cross multiply :5x = 2y
y = 5/2
y = 2.5x
(x + 70) / (y + 300) = 1/3
Cross multiply :210 + 3x = 300 + y
Substitute for y
210 + 3x = 300 + 2.5x
300 - 210 = 3x - 2.5x
90 = 0.5x
x = 90 / 0.5
x = 180
Total tickets sold = 180 + 70 = 250

Answer:
14 4/9 cans
Step-by-step explanation:
We need to add the cans used on Saturday and Sunday
10 7/9 + 3 4/6
We can simplify the fraction 4/6 by dividing the top and bottom by 2
10 7/9 + 3 2/3
To add, we need the fractions to have a common denominator of 9
10 7/9 + 3 2/3*3/3
10 7/9 + 3 6/9
Add the whole numbers 10 +3 = 13
Add the fractions 7/9 + 6/9 = 13/9
13/9 = 1 4/9
Move the whole part of the fraction to the whole numbers
13 + 1 + 4/9
14 4/9
