A 2 / 3
B 4 / 5
C 5 / 4
D 3 / 2

Answer: A 2/3

Explanation:

2 divided by 3 = .6667
If you multiply 12 by .6667 you get 8
if you multiply 15 by .6667 you get 15

As you can see they used 2/3 as the scale factor to go from 12x15 to 8x10

Hope this helps!

Bob ust choose a shirt and a pair of pants for today's outfit. He has 2 shirts and 3 pairs of pants to choose from how many different outfits can he make.​

Answers

He can make 6 different outfits.

Answer:

6 outfits.

Step-by-step explanation:

Bob has 2 shirts and 3 pairs of pants. That means he can wear one of the two shirts with any of the three pants (which'd make 3 outfits) and then with the other shirt with any of those three pants again (which'd make another three outfits.

Since you want to find out how many outfits Bob can make using the five articles of clothing, therefore 3+3=6 and 6 outfits would be your answer.

If you want to think of this problem another way, in simpler terms you can think of it like this: 2*3=6. Two shirts times three pants, which equals to six that makes our answer Bob can make six different outfits from his options above.

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.

Could someone please help me?

Answers

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

The salaries of three employees are listed below. Each employee was recently given a raise.


Salary
Employee [before raise] Raise
Jane $41,000 4%
John $43,400 4.5%
Jack $39,400 3%

What is the total of all three raises?
A. $4,775
B. $14,237
C. $4,704
D. $10,523

Answers

Step-by-step explanation:

Don't worry we will take care of everything. It's easy. listen carefully

1. we know the salary of each employee, before raise. and also their raise %age.

2. CONCEPT:- FOR EMPLOYEE (JANE) -

AMOUNT RAISED ON HER SALARY= 4% of $41000

= ( 4/100)× 41000

= $1640 (this is the raised amount in jane original salary)

3. similarly , you can also find raised amount for jhon and jack which will be $1953 and $1182 respectively.

4. for final solution, you just have to add all the raised amount in their original salary. hence final solution will be

= $1640 + $1953 + $1182

= $ 4775 (final solution).

All three raises are letter d
