A bakery the price of the cake is nine dollars more than the price of a pie. One day the bakery sold 8 cakes and 14 pies for a total of $402. The system of equations below can be used to find c the cost in dollars of a cake and P the cost in dollars of a pie. What is the price of a cake?

Answers

Answer:

The price of the cake is $24 and the price of the Pie is $15

Step-by-step explanation:

Given

Represent price of Cake with C and Price of Pie with P

[tex]C = 9 + P[/tex]

Cakes sold = 8

Pies sold = 14

[tex]Total = \$402[/tex]

Required

Determine C and P

To represent the cakes and pies sold, we have the following expression

[tex]8C + 14P = 402[/tex]

Substitute 9 + P for C

[tex]8(9+P) + 14P = 402[/tex]

Open the bracket

[tex]72 + 8P + 14P = 402[/tex]

Collect Like Terms

[tex]8P + 14P = 402 - 72[/tex]

[tex]22P= 330[/tex]

Divide both sides by 22

[tex]P = \frac{330}{22}[/tex]

[tex]P = 15[/tex]

Recall that

[tex]C = 9 + P[/tex]

[tex]C = 9 + 15[/tex]

[tex]C = 24[/tex]

Hence, the price of the cake is $24 and the price of the Pie is $15

One positive number is 6 times another number. The difference between the two numbers is 205. Find the numbers. (Enter your answers as a comma-separated list.)

Answers

Answer:

Hence the positive numbers are 246, and 41

(246, 41)

Step-by-step explanation:

From the question,

One positive number is 6 times another number

Let the first positve number be [tex]x[/tex]

and the other number be [tex]y[/tex]

Hence,

[tex]x = 6y[/tex] ....... (1)

Also,

The difference between the two numbers is 205

That is,

[tex]x - y =205[/tex] ........(2).

To solve for the two unknowns, substitute the value of [tex]x[/tex] in equation (1) into equation (2).

Since,

[tex]x = 6y[/tex]

Then

[tex]x - y =205[/tex] becomes

[tex](6y) - y =205\\[/tex]

Then,

[tex]6y - y = 205\\5y = 205\\[/tex]

Divide both sides by 5

[tex]\frac{5y}{5} = \frac{205}{5} \\ y = 41\\[/tex]

∴ the value of [tex]y[/tex] is 41

Now, substitute the value of y into equation (1) to find [tex]x[/tex]

Then,

[tex]x = 6y[/tex] becomes

[tex]x = 6(41)\\x = 246\\[/tex]

∴ the value of [tex]x[/tex] is 246

Hence the positive numbers are 246, and 41

There are three numbers. The first number is twice the second number. The third number is twice the first number. The sum of the three numbers is 112.

Answers

Answer:

x = 32 y = 16 z = 64

Step-by-step explanation:

x is the 1st number

y is the 2nd number

z is the 3rd number

The first number is twice the second number so

x = 2 y

The third number is twice the first number.

z = 2 x

Their sum is 112

x + y + z = 112

Plus in what we know:

x + y + z = 112

2 y + y + 2x = 112

3y + 2x = 112 Let's solve for y and subtract 2x from each side

3y = 112 - 2x  Divide both sides by 3

y = [tex]\frac{112 - 2x}{3}[/tex]

Now plug our answer back in to solve for x.

x = 2y

x = 2 ( [tex]\frac{112 - 2x}{3}[/tex] )

x = (224 - 4x) / 3    Multiply each side by 3.

3x = 224 - 4x         Add 4x to each side

3x + 4x = 224

7x = 224              Divide each side by 7

7x / 7 = 224 / 7

x = 32

Now we can solve for z.

z = 2x

z = 2 ( 32 )

z = 64

Now we can solve for the numerical value of y.

x + y + z = 112

32 + y + 64 = 112

96 + y = 112       Subtract 96 from each side.

y = 112 - 96

y = 16

Answer:

1st number = 36

Second = 16

Third = 64

Step-by-step explanation:

We have 3 numbers

Let's call the second number g

Then the first would be , 2x g = 2g

Then the third would be twice the first = 2 x 2g = 4g

We add up all numbers and equate it to 112

2g + g +4g = 112

7g = 112

g = 112/7

g = 16

First number = 2g = 2x16 = 32

Second number = g = 16

Third number = 4g = 4x16 = 64

Therefore the numbers are 32, 16, 64.

1. A standard dice has 6 sides with the numbers 1-6 on it. What is the probability of rolling a 4 on a
standard dice?

Answers

Answer:

1/6

Step-by-step explanation:

There are six sides on a die and only one of them has a 4

P( 4) = number of sides with a 4/ total number of sides

        = 1/6

Answer:

P (4) = 1/6

Step-by-step explanation:

The probability can be found by creating a fraction. The numerator is the number of favorable outcomes and the denominator is the total number of outcomes.

P (4) = sides with a 4 / total sides

The standard dice has 6 sides numbered 1 through 6.

P (4) = sides with a 4/ 6

Only one side on the cube has a 4.

P (4) = 1/6

This fraction cannot be simplified further, so it is our final answer.

The probability of rolling a 4 on a standard dice is 1/6

Enter the sum of numbers as a product of their GCF. 75 + 30 The sum of the numbers as a product of their GCF is

Answers

Answer: 75+30 = 15 x 7

Step-by-step explanation:

The given expression is 75+30 (=105) which defines the sum of 75 and 30.

Prime factorization of 75 and 30 are as below:

75 = 5 x 5 x 3

30 = 5 x 3 x 2

GCD (75,30) = 5x 3 = 15  [Note: GCD = Greatest common divisor]

Consider 75+30 = (15 x 5) + (15 x 2)   [75 = 15 x 5 and 30= 15 x 2]

=  15 (5+2)   [taking 15 as common ]

= 15 x (7)

(=105)

So,  75+30 which is sum of the numbers and it is expressed as 15 x 7 which  a product of their GCF.

Given values:

The bank statement balance= $2,253.18

The checkbook balance = $2,324.34

outstanding check amounts= $105.50 and $158.10

transit amount= $605.27

account earnin(credits)= $68.51

service charge= $5.00

Adjusted Checkbook Balance =?

Adjusted the Checkbook Balance:

checkbook balance = $2,324.34

[tex]\text{total checkbook balance = checkbook balance+ credits}\\[/tex]

                                      [tex]= \$ 2,324.34+ \$ 68.51\\\\= \$ 2392.85[/tex]

Adjusted the Statement Balance:

bank statement balance= $2,253.18

[tex]\text{total Statement balance = bank Statement balance+ transit amount}\\[/tex]

                                      [tex]= \$ 2,253.18+ \$ 605.27\\\\= $ 2,858.45[/tex]

                                           [tex]= \$263.60[/tex]

Step-by-step explanation:

let x be the number then the other number is 2x + 9, then

x + 2x + 9 = 129, that is

3x + 9 = 129 ( subtract 9 from both sides )

3x = 120 ( divide both sides by 3 )

x = 40

Thus the numbers are

x = 40 and 2x + 9 = 2(40) + 9 = 80 + 9 = 89
