please help:(
Punnett squares

need help with these three, if anybody can help id really appreciate it.

let the price of pizza and soda( per 2 litre bottle) be x and y

from 1st condition

12x+2y=137.6.....(1)

from 2nd condition

x+y =11.95.......(2)

multiply eq. (2) by 2

2x+2y=23.9.....(3)

subtracting (1) and (3)

12x+2y=137.6

2x+2y= 23.9

10x = 113.7

x=113.7/10

x=11.37

2(11.37)+2y=23.9

22.74+2y=23.9

2y=23.9-22.7

2y=1.2

y=0.6

So the prices of  the pizza and soda are 11.37 and 0.6 dollars.

Each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Let x be the cost of one pizza, and y be the cost of one 2-liter of soda.

According to the information given, we can write the following two equations:

1. For the pizza and soda purchased for the theater party:

12x + 6y = 137.64

2. For the pizza and soda purchased for Katya's family:

1x + 1y = 11.95

Now, we have a system of two equations with two variables. We can solve it to find the values of x and y.

First, let's solve the second equation for y:

y = 11.95 - x

Next, substitute this value of y into the first equation:

12x + 6(11.95 - x) = 137.64

Now, simplify and solve for x:

12x + 71.7 - 6x = 137.64

Combine like terms:

6x + 71.7 = 137.64

Subtract 71.7 from both sides:

6x = 65.94

Finally, divide by 6:

x = 65.94 / 6

x ≈ 10.99

Now that we have the value of x, which is the cost of one pizza, we can find the cost of one 2-liter of soda using the second equation:

y = 11.95 - x

y ≈ 11.95 - 10.99

y ≈ 0.96

So, each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Answer:

Total amount pay for potatoes = 50.2

Step-by-step explanation:

Given:

Levi buys cookies and potatoes

Total amount pay for cookies = 5.49

Total amount pay by Levi = 55.69

Find:

Total amount pay for potatoes

Computation:

Total amount pay for potatoes = Total amount pay by Levi - Total amount pay for cookies

Total amount pay for potatoes = 55.69 - 5.49

Total amount pay for potatoes = 50.2

Step-by-step explanation:

x=4+23

Answer:

A

Step-by-step explanation:

hello :

8(e)^2x+1=4

(e)^2x+1=4/8 = 1/2

so : 2x+1 = ln(1/2)

2x = ln(1/2) - 1

x = (ln(1/2) - 1)/2

The solution to the given exponential function is x = [ ln(0.5) - 1]/2

The standard exponential equation is expressed as  y = ab^x

Given the expression

8(e)^2x+1=4

Divide both sides by 8

(e)^2x+1=4/8

(e)^2x+1 = 1/2

Take the ln of both sides

ln(e)^2x+1  ln(1/2)
2x + 1 = ln(0.5)

2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2

Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2

Step-by-step explanation:

25 min. to get to the library

1-hour story = 60 min.

25 min. to go back home

25 + 25 + 60 = 110 min.

110. min = 1.83333 hrs.

9:15 am + 1.83333 = 10.98333 am

98 - 60 = 38

60 = 1 hr. -----> 60 + 60 = 120 minutes -----> 2 hrs.

Answer:

[tex] \boxed{y = 10} [/tex]

Step-by-step explanation:

-12 = 6y + 18 – 9y

[Group like terms 6y and -9y]

-12 = (6y – 9y) + 18

[Simplify the expression]

-12 = -3y + 18

[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]

-12 = -3y + 18

–18 –18

-30 = -3y

[Divide by -3 from both sides, division property of equality, to get the variable y by itself]

-30 = -3y

÷(-3) ÷(-3)

10 = y

[Symmetric property of equality, if b = a, then a = b]

y = 10

Answer:

12meters

Step-by-step explanation:

Given data

Lenght = 36 meters

Width = 15 meters

The dimension of the diagonal can be gotten via Pythagoras theorem

D^2= L^2+W^2

Substitute

D^2= 36^2+ 15^2

D^2=  1296+225

D^2= 1521

D= √1521

D= 39  meters

Hence the distance while walking on the side is

=36+15

=51 meters

Hence the difference is

=51-39

=12meters

Answer:

The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.
