9n + 15 < = 10n + 24
9n - 10n < = 24 - 15
-n < = 9
n > = -9
Answer:
It seems each number is 3 less than the previous number.
We must sum these 10 numbers
40, 37, 34, 31, 28, 25, 22, 19, 16, 13
The sum would equal the average of the middle 2 numbers times 10.
(28 + 25) / 2 = 53 / 2 = 26.5
We multiply by 10 because there are 10 numbers and this equals
265

Answer:
C. 4 X (3 + 8 – 6)
Step-by-step explanation:
3 + 8 = 11
11 - 6 = 5
5 x 4 = 20
Distance÷time
440÷8= 55
Therefore he needs to drive at the speed of 55 miles/hour
The linear equation has an equal signed involved and the expression doesn’t.
