Answer:
$6.75
Step-by-step explanation:
1: In this explanation, let's let one watermelon be w, and one orange be o.
2: From the passage, 1w + 5o = $11.
3: Also from the passage, 3w + 5o = $24.50
4: We can then use a simultaneous equation to work them out - both equations we have use 5 oranges.
3w + 5o = 24.5 (equation 1)
1w + 5o = 11 (equation 2)
5: We can now take the second equation away from the first :
3w - 1w = 2w, 5o - 5o = 0, 24.5 - 11 = 13.5
Now we know 2w = 13.5
6: If 2w = $13.50, one watermelon will be half of that, so $6.75
Hope this helps, let me know if you have any further questions :)

Step-by-step explanation:
Part 1) we have

To calculate the division problem convert the decimal number to fraction number
so

Remember that
Since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom fraction

Simplify
Divide by 22 both numerator and denominator

Part 2) we have

To calculate the division problem convert the mixed number to an improper fraction

so

Since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom fraction

Convert to mixed number

Part 3) we have

Since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom fraction

Simplify
Divide by 5 both numerator and denominator

Part 4) we have

To calculate the division problem convert the mixed number to an improper fraction

so

Since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom fraction

8x +9 = 6x + 21 where x = number of chairs in each row
2x=12
x=6
sub back into original equation 8 x 6 + 9 =57 chairs
Is 7x+7 and then what. Iam confused
