Answer:
3 , 1 , -1 , -3
Step-by-step explanation:
5 - 2n
n = 1 ; 5 - 2n = 5 - 2*1 = 5 - 2 = 3
n = 2; 5 - 2n = 5 - 2*2 = 5 - 4 = 1
n = 3; 5 - 2n = 5 - 2*3 = 5 - 6 = -1
n = 4; 5 -2n = 5 - 2*4 = 5 - 8 = -3
First 4 terms are : 3 , 1 , -1 , -3
Answer:
85%
Step-by-step explanation:
If 30 of them have their own lawn service then that means 170 of them do not have their own lawn service.
Seeing as there are 200 houses in total, the fraction of people who don't have lawn service is 170/200. This is equal to 0.85 or 85%.
The answer is r=-3. You use the distributive property which is basically multiplying -8 with all the numbers inside the parenthesis. So -8 x r and -8 x -2. This results to -8r+16=40 (Two negative numbers multiplied together will form a positive number). We use inverse operations to subtract 16 from both sides. 16-16 is 0 and 40-16 is 24. So we are left with -8r=24. We want to be left with only r, so we once again use inverse operations to divide -8 from both sides. -8/-8 is 1, and 24/-8 is -3. So we end up with r=-3. Hope this helped :]
