HELP PLSS I'm Desperate

Answers are in bold in the explanation.

Step-by-step explanation:

1878 x 1000 = 187800

493 x 1000 = 493,000

73 x 1000 = 73000

8 x 1000 = 8000

1,878g = 1.878kg

493g = 0.493kg

73g = 0.073kg

8g = 0.008kg

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
