1. Car Mart sell 11 cars per day.
You can use the table by looking at day 2 and day 3. You can see underneath it, it shows how many cars is left after that particular day. So from day 2, you have 43 cars left and day 3, you got 32 cars left. From 43 car to 32 car is losing 11 car. So each day the Car Mart sell 11 car.

2. First we know that after 3 days, Winston have 32 cars left and after 5 day, it has 12 cars left.
Here’s the chart that I made for Winston:
Each day, Winston’s sell 10 cars. (Lose 10 cars per day)

What is the pattern (these are not ratios) 11 to 25, 27 to 41, 43 to 57, 59 to 73, __ __ __ __ __ __ __ __
Nuetrik [128]

Answer:

75, 89, 91, 105, 107, 121, 123, 137

Step-by-step explanation:

If you analyze how much each number is increased, you will notice it alternates between adding 2, then adding 14:

11 + 14 = 25.

25 + 2 = 27.

27 + 14 = 41.

41 + 2 = 43.

43 + 14 = 57.

57 + 2 = 59.

59 + 14 = 73.

That means you can simply, finish the pattern, alternating between adding 2 and 14. Then you will get these answers.

Four families went out for lunch. The total food
dybincka [34]

Answer:

Each family spent about 34.25 on dinner

Step-by-step explanation:

$167 - $30 (tip) = 137

137 ÷  4 (for each family) = 34.25

BUT

if each family is seperate than they each spent about 11.75 on dinner

167 - (30 x 4) = 47

47 ÷  4 = 11.75

I'm pretty sure the first one is the answer though

64, –48, 36, –27, ...
frozen [14]
The only formula that can be used to describe the sequence is definitely the third one f(x + 1) = -3/4 f(x). So count like that64* -\frac{3}{4}  = -48
48* -\frac{3}{4} = 36 and so on. You can check others by yourself to check if I'm right or not.
