Answer:

70, 140, 280, 350

Step-by-step explanation:

Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.

Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...

So, the four smallest numbers with prime factors of 2, 5, and 7 are ...

70 = 2·5·7

140 = 2²·5·7

280 = 2³·5·7

350 = 2·5²·7

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

Elodia [21]

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!
