Common denominator.

(7-3t) -5(-1.6t +5)
Find the difference!
Pls I need this before an hour!!!

Answers

Answer:

5t - 18

Step-by-step explanation:

(7 - 3t) - 5(-1.6t + 5)

First, we need to distribute the right side to get rid of the parentheses.

-5 * -1.6t = 8t

-5 * 5 = -25

8t - 25

Now, we have

(7 - 3t) + 8t - 25

We no longer need the parentheses on the left side.

7 - 3t + 8t - 25

Combine like terms.

-3t and 8t are like terms.

-3t + 8t = 8t - 3t

8t - 3t = 5t

7 and -25 are like terms.

7 - 25 = -18

5t - 18

Because 5t and -18 are NOT like terms, this is as far as we can simplify. So, we have our answer.

Please let me know if you have any further questions. I'm always happy to help!

Answers

Answer:

Step-by-step explanation:

The number of ways in which the song arrangements are possible for Sara and Ben's playlist, assuming that no song is repeated is 3,628,800.

What is a factorial?

The product of a whole number 'n' with every whole number until 1 is called the factorial. The factorial of 4 is, for example, 43221, which equals 24.

Given that Sara and Ben, Each choose 5 songs for the playlist. Therefore, the total number of songs is 10. Also, songs are needed to be arranged so that none of them repeats. Therefore, the number of ways these 10 songs can be arranged is,

The number of ways = 10!

= 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 3,628,800

Therefore, the number of ways in which the song arrangements are possible for Sara and Ben's playlist, assuming that no song is repeated is 3,628,800.

The sum of two numbers is 52. The greater number is 4 more than the smaller number. Which equation can be used to solve for the smaller number? (5 points)

Select one:
a. x − (x + 4) = 52
b. x + (x + 4) = 52
c. x(x + 4) = 52
d. x(x − 4) = 52

Answers

Should be B

Because if it were C or D it would be the product and not the sum

b

if the smaller number is 4 more it can be represented as x+4 and then you add x to the greater number to get 52 which is why the equation is x+(x+4)=52
