Under ratio and proportion, there are a couple of ways you can use aside from using words to establish the relationship between 2 numbers.
One would be in a fraction form where "3 to 10" can be written as "3/10", or using a colon between the two numbers, where it would be written as "3:10". It is necessary to understand that these forms all mean the same, even if they look really different.
Answer:
3rd, 4th and 5th are function...
Use proportions.
(a)
2 workers are to 19 as x workers are to 38
2/19 = x/38
x = 4
(b)
2/19 = x/76
x = 8
(c)
2/19 = x/133
19x = 2 * 133
19x = 266
x = 14
I can't see the table, but you find the total amount that the entire fifth grade made and divide it by six. I would round it to the nearest hundredth.
8!in is the initial value at 0 days which represents b=8
The rate of change is 3in per day, this rate is the slope m = 3
Now substitute
y = 3x + 8
