5. rational number
7. opposite of 1/3 is -1/3 and opposite of -7/12 is 7/12
8. absolute value of 9.8 is 9.8 and absolute value of -10/3 is 10/3
Answer:
f(n) = 6n + 12
Step-by-step explanation:
There is a common difference in consecutive number of seats, that is
42 - 36 = 36 - 30 = 30 - 24 = 24 - 18 = 6
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 18 and d = 6 , then
f(n) = 18 + 6(n - 1) = 18 + 6n - 6 = 6n + 12
A.) 155
123 + 47 + 35 = 205
Subtract 205 with 360 (360 is the measure of a circle) and you will be left with 155°.
891 were sold
.55x1800= 990
10% of 990 roses is 99 (99 is left over)
990-99= 891
Answer: -2
Explanation: On the image we can see it goes down 4 units and right 2. Giving us the slope
Simplified that is -2 which is the slope of the line
