Answer:

Answer:

3rd and 4th options are correct that is 24 hours per day and 7 days per week.

Step-by-step explanation:

We need to find the conversion factors that can be used to find number of hours in a week.

We know that,

Number of hours in a day = 24

and

Number of days in a week = 7

So, Number of hours in 7 days = 24 × 7 = 168.

Therefore, 3rd and 4th options are correct that is 24 hours per day and 7 days per week.

Solve the following:2(x+3)=x-4

Answers

To solve the equation 2(x+3) = x-4, you can follow these steps:

1. Distribute the 2 on the left side of the equation to both terms inside the parentheses:
2x + 6 = x - 4

2. Now, let's isolate x on one side of the equation. You can do this by subtracting x from both sides:
2x - x + 6 = -4

3. Simplify the left side by combining like terms (2x - x):
x + 6 = -4

4. To isolate x, subtract 6 from both sides of the equation:
x + 6 - 6 = -4 - 6

5. Simplify both sides:
x = -10

So, the solution to the equation is x = -10.

Rewrite 2 2/5 as an improper fraction.

Answers

2 = 10/5

10/5 + 2/5 = 12/5

Answer:

2 2/5=12/5

Step-by-step explanation:

Step 1: multiply the denominator by the whole number. 5x2=10

Step 2: add the answer from step 1 to the numerator. 10+2=12

Step 3: write answer from step 2 over the denominator. 12/5

=12/5

5x2+2=12

5=5

Which pattern could be used to create the sequence?400, -200, 100, -50, 25
a) Multiply the previous term by -2
b) Divide the previous term by -2
c) Subtract 600 from the previous term
d) Add -200 to the previous term

Answers

As you are given multiple choice, you can use trial and error with each of the answers. You can see that with each number the sign before it is reversed (so it goes even, odd , even , odd etc.) and the numbers are halved each time. 
The answer is B) because you are dividing by 2 each time, and changing the sign before the number.
The answer would be b. It is b because if you do 400 divided by -2 is -200 and then you just keep dividing by -2
