We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes o
Zina [86]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.

The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:

2x + 3y + 4z = 15.3         (1)

The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:

4x + y + 2z = 10.9       (2)

The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:

5x + 2y + z = 13.7        (3)

Solving equation 1, 2 and 3 simultaneously gives:

x = $1.5, y = $2.5 and y = $1.2

The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2

Each circle counts as one whole, Write a mixed number giving the amount shaded. Then, write this amount as an improper fraction.
devlian [24]

Answer:

2 \frac{2}{5}

\frac{12}{5}

Step-by-step explanation:

As a mixed fraction, There are 3 circles with 5 pieces in each so our denominator will be 5

The number that is shaded is 2 whole circles so that is 10 and 2 out of 5 of last one.

The whole number is 2 and the fraction for the last circle is 2/5 so our mixed number is

2 \frac{2}{5}

Now to find the improper fraction turn 2 into a fraction with 5 as a denominator.

\frac{2}{1}  \times  \frac{5}{5}

Which equal

\frac{10}{5}

Then add 2/5 to 10/5

\frac{10}{5}  +  \frac{2}{5}  =  \frac{12}{5}
