Answer:

Step-by-step explanation:

Step 1 is to collect the information in a table format.  The attached Table1 summarizes what we know in columns 1 - 3. Columns 4 - 6 show the data we're about to calculate, so ignore them for the moment.

.I use A for the price of one apple and C for the price of 1 chocolate bar.  We know how many of each are purchased by both Mary and Bill, and the total each paid.  

The last column (6) shows the price for each, which comes from the derivation presented below.

We can set the information in columns 1 - 3 into equations:

Mary:  3A+1C = 2.70   [This states that Mary bought 3 apples at a price of A for each apple, and 1 chocolate bar at a price of C per bar.]

Bill:      1A + 4C = 6.40  [In the same fashion, this summarizes how Bill parted with his $6.40]

---

Now let's rearrange either equation to solve for C.  I'll use Mary's equation:

3A+1C = 2.70

1C = 2.70 - 3A

This tells us that the price of 1 chocolate bar is $2.70 minus the cost of 3 apples.  Interesting, but we need the price of a chocolate bar to determine an exact amount.

----

Now take Bill's equation and substitute the value we just derived for the price of a chocolate bar C = (2.70-3A).

1A + 4C = 6.40

1A + 4(2.70 - 3A) = 6.40

1A + 10.80 - 12A = 6.40

-11A = -4.40

A = 0.40    This is the price for 1 apple.  This is the value in the last column (6) of attached Table1.

---

Now we can use the value of $0.40 in either equation to find the price of a chocolate bar.  I'll use the rearranged equation we developed for Mary:

1C = 2.70 - 3A

1C = 2.70 - 3(0.40)   [A = 0.40 from the above work]

1C = 2.70 - 1.20

1C = 1.50

The price of 1 chocolate bar is $1.50.  Pricey, and bad for health.  But very tasty.

Columns 4 and 5 are the total costs for the apples and bars bought by each, and their sums add up to the amounts we were given at the start of the problem.  So our prices must be correct.

The number of ways it is possible for the gold, silver, and bronze medals to be awarded is 1320 ways

Permutation are related to arrangement and combination has to do with selection.

If there are 12 teams, each representing a different country and the possible awards are gold, silver, and bronze medals, the number of ways they can be selected is given as:

12P3 = 12!/(12-3)!

12P3 = 12!/9!

12P3 = 12 * 11 * 10

12P3 = 1320 ways

Hence the number of ways it is possible for the gold, silver, and bronze medals to be awarded is 1320 ways

Answer:

The new dimensions are 6 ft and 4 ft.

Step-by-step explanation:

Let x = side of original square.

The sides are increased by 3 ft and 1 ft, so the new side lengths of the rectangle are

x + 3 and x + 1

The area of the rectangle is length × width.

area = (x + 3)(x + 1)

area = x² + 4x + 3

The area is 24 ft².

x² + 4x + 3 = 24

x² + 4x - 21 = 0

(x + 7)(x - 3) = 0

x + 7 = 0 or x - 3 = 0

x = -7 or x = 3

x + 3 = 3 + 3 = 6

x + 1 = 3 + 1 = 4

The new dimensions are 6 ft and 4 ft.

Answer:

linear equation is the equation having degree 1 like ax+by=c so option B is correct ..

y+7=5x will be treated as the linear function.  Thus, option B is correct.

Any formula with one or two variables and no exponents is said to be linear. On the coordinate plane, this property depicts a straight line. In order to maintain the same function's linear illness, extra variables in a function must be constant.

y+7=5x

This equation can be written in a proper form:

y=5x-7

As this equation does not have any power therefore this will be treated as a linear function.

Answer:

9x7=63

Step-by-step explanation:

just use a calculator for multiplication

The product of 9 and 7 is 63. In other words, the result of multiplying 9 and 7 is 63.

To find the result of multiplying 9 and 7, by follow a step-by-step process.

First, start by writing the multiplication expression as 9 multiplied by 7.

Next, multiply the digit in the ones place of the first number (9) with the digit in the ones place of the second number (7).

In this case, 9 multiplied by 7 equals 63.

Then, move to the tens place of the second number (7) and multiply it with the digit in the ones place of the first number (9).

Since there is no digit in the tens place of the first number, skip this step.

Finally, add the products obtained from the previous steps.

In this case, there is only one product, which is 63.

Therefore, the result of multiplying 9 and 7 is 63.

Multiplication is a fundamental arithmetic operation used to determine the total value when a number is repeated a certain number of times. In this case, multiplying 9 by 7 represents adding nine 7s together.
