a_{1} = 1² + 7 = 1 + 7 = 8

a_{2} = 2² + 7 = 4 + 7 = 11

a_{3} = 3² + 7 = 9 + 7 = 16

a. It is rewritten as 15/4 + 4⅓

b. The fraction would be positive

c. The solution as a mixed fraction is: 8\frac{1}{12}

<h3>What is a Mixed Fraction?</h3>

A mixed fraction is a number that has a combination of a fraction part and a whole number. For example, 2⅓ is a mixed fraction.

Given the expression,  15 / 4 – (-4⅓), the steps below can be used to solve the fractional expression as a mixed fraction:

a. Rewrite as addition:

15/4 + 4⅓ [note, minus multiplied by minus = plus]

b. The answer would be positive because we are adding two positive fractions.

c. Solve as mixed fraction as shown below:

15/4 + 13/3

The common denominator of the two fractions is 12, thus:

= [3(15) + 4(13)]/12

= [45 + 52]/12

= 97/12

Express as mixed fraction:

97/12 = 8\frac{1}{12}

Rasheed is buying wings and quesadillas for a party. A package of wings costs $8. A package of quesadillas costs $10. He must sp
galina1969 [7]

Answer:

10 is maximum of packages of quesadillas.

Step-by-step explanation:

x= number of wings

y= number of quesadillas

x+y=20

8x+10y=$160

if x=7

then 7+y=20

20-7=14=y

14*10=140

8*7=56

Rasheed can't buy 20 packages, since it'll go over his budget.

So 160-56=104

And 104/10= 10 minimum

10*10=100

100+56=160

So he can buy 10 packages of quesadillas.
