Answer:

(a) The system of equations that could be used to find the length (in hours) of each type of workout is:

- Equation 1: 3x + 5y = Total hours on Friday

- Equation 2: 5x + 7y = Total hours on Saturday

where x is the length (in hours) of each Plan A workout and y is the length (in hours) of each Plan B workout.

(b) To find the length of each type of workout, we need to know the total hours that Susan trained on Friday and Saturday. Once we have that information, we can solve the system of equations using either the substitution or elimination method.

(c) To find the length of each type of workout, we can either solve the system of equations ourselves or use a calculator or online tool (like Wolfram Alpha) to solve it for us. Once we have the solution, we can plug it back in to the equations to make sure it works.

For example, if the total hours on Friday were 12 and the total hours on Saturday were 18, the solution would be:

- x (Plan A) = 2 hours

- y (Plan B) = 4 hours

And plugging it

Sofia needs 8 inches of ribbon to make 1 party favor. Which of the following lengths would be enough ribbon for Sofia to make from 15 to 20 party favors? 1 inch 5 2.54 centimeters, 1 centimeter < 0.39 inch
A 61 centimeters
B 390 centimeters
C 405 centimeters
D 411 centimeters
E 490 centimeters

Answers

First, we need to determine how much ribbon Sofia needs for each party favor. Since she needs 8 inches of ribbon for one party favor, we can convert that to centimeters (since the answer choices are given in centimeters):

8 inches x 2.54 cm/inch = 20.32 cm

So Sofia needs 20.32 cm of ribbon for each party favor.

To find out how much ribbon she needs for 15 to 20 party favors, we can multiply the amount needed for one party favor (20.32 cm) by the number of party favors:

15 party favors x 20.32 cm/party favor = 304.8 cm
20 party favors x 20.32 cm/party favor = 406.4 cm

The closest answer choice to this range is C, 405 centimeters. Therefore, C is the correct answer.

Answer:

D: 411 centimeters

Step-by-step explanation:

Multiply 8 by 15 you'll get 120 inches from thisMultiply that by 2.54 to find how many centimeters it is. It would be 304.8 centimeters.Then repeat steps 1-2 but replace 15 inches with 20 inches. When you multiply it by 8 it becomes 160 and it becomes 406.4 centimeters when it's multiplied by 2.54 which is why the correct answer is D

Write the other side of this equation so it's true for no values of x:

1/3(12x + 18) + x

Answers

To make the equation true for no values of x, we need to make sure that the left-hand side and the right-hand side are not equal for any value of x.

Let's simplify the left-hand side of the equation first:

1/3(12x + 18) + x
= 4x + 6 + x
= 5x + 6

To make this equation true for no values of x, we need to find an expression that is never equal to 5x + 6. One way to do this is to take the negative of 5x + 6:

-(5x + 6)

Now the full equation is:

1/3(12x + 18) + x = -(5x + 6)

We can simplify the left-hand side again:

1/3(12x + 18) + x
= 4x + 6 + x
= 5x + 6

And substitute it into the equation:

5x + 6 = -(5x + 6)

Simplifying this equation gives:

10x + 12 = 0

Dividing both sides by 10 gives:

x + 6/5 = 0

x = -6/5

So the original equation, 1/3(12x + 18) + x = -(5x + 6), is true for no values of x.
