Emily and her children went into a grocery store and she bought $20.80 worth of bananas and peaches. Each banana costs $0.80 and

MakcuM [25]

Answer:

The number of bananas that Emily bought was 6 and the number of peaches that Emily bought was 8

Step-by-step explanation:

The complete question is

Emily and her children went into a grocery store and she bought $20.80 worth of bananas and peaches. Each banana costs $0.80 and each peach costs $2. She bought a total of 14 peaches and bananas altogether. Determine the number of peaches and the number of bananas that Emily bought

Let

x ----> the number of bananas that Emily bought

y ----> the number of peaches that Emily bought

we know that

She bought a total of 14 bananas and peaches altogether

$x+y=14$ -----> equation A

She bought $20.80 worth of bananas and peaches

$0.80x+2y=20.80$ -----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (6,8)

see the attached figure

therefore

The number of bananas that Emily bought was 6 and the number of peaches that Emily bought was 8

Martina drove 715 miles in 13 hours. at the same rate, how long would it take her to drive 495 miles?

Natali5045456 [20]

First you need to get the unit rate by dividing 715 by 13, getting 55 miles per hour. You then will need to divide 495 by 55 to get the answer of 9

Give an example of: degree of a polynomial is the highest sum of one of its terms, explain.

yuradex [85]

Example 1 Perform the indicated operation for each of the following.

(a) Add to

(b) Subtract

Solution

(a) Add to .

The first thing that we should do is actually write down the operation that we are being asked to do.

In this case the parenthesis are not required since we are adding the two polynomials. They are there simply to make clear the operation that we are performing. To add two polynomials all that we do is combine like terms. This means that for each term with the same exponent we will add or subtract the coefficient of that term.

In this case this is,

[Return to Problems]

(b) Subtract from .

Again, let’s write down the operation we are doing here. We will also need to be very careful with the order that we write things down in. Here is the operation

-. If 5 + 4 = 9, does (5 + 4) = 3 = 9 = 4? Why or why not?

Serjik [45]

Answer:No because if you add 5 plus 4 you will get nine but when u subtract 5 from four you will get 1 so no it would not get you any of those
