Bananas are $1.29 per pound. We need to know how much bananas cost 1.2 pounds.

We can split 1.2 into different parts. One easy way is to split 1.2 into six 0.2s.
1 pound can be split into five 0.2s.
To figure out the price of 0.2 pounds of bananas, we divide $1.29 by 5.
1.29 divided by 5 is equal to 0.258.
0.258 * 6 = 1.548
$1.548 rounded to the nearest cent is $1.55.

Simplify this expression
kompoz [17]
The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:
\frac{x+2}{ x^{2} -6x-16} × 9x
Write -6x as a difference.
\frac{x+2}{ x^{2} +2x-8x-16} × 9x
Factor out x from x² + 2x.
\frac{x+2}{ x X (x+2)-8x-16} × 9x
Factor out -8 from -8(x + 2).
\frac{x+2}{ x X (x+2)-8(x+2)} × 9x
Factor out x + 2 from the denominator (bottom) of the expression.
\frac{x+2}{(x+2)X(x-8)} × 9x
Reduce the fraction with x + 2
\frac{1}{x-8} × 9x
Finally,, calculate the product to find your final answer.
\frac{9x}{x-8}
This means that the correct answer to your question is going to be option B.

Mrs. Jackson bought 2/3 pound of bananas at $.51 per pound, 1 1/4 pounds of peaches for $2.00 per pound, 1/2 gallon of orange ju
Aleks04 [339]

Answer:

$11.47

Step-by-step explanation:

In order to calculate Mrs.Jackson's total we first need to turn the fractions into decimals by simply dividing the numerator by the denominators like so...

2/3 = 0.66

1 1/4 = 1.25

1/2 = 0.50

Now we need to multiply each products cost by the amount they bought in decimal form, then finally add them all together...

($0.51 * 0.66) + ($2 * 1.25) + ($4.50 * 0.50) + ($3.19 * 2) = x

0.34 + 2.5 + 2.25 + 6.38 = x

$11.47 = x

Finally, we can see that Mrs. Jackson's total was $11.47
