This is your typical algebra question where you are looking for an unknown value given some information. The information can be set up as:
8 - x = 4*(x +3)
Distribute the 4:
8 - x = 4x + 12
Rearrange to get variables on one side:
8 - 12 = 4x + x
Simplifiy:
-4 = 5x
Isolate the variable:
-4/5 = x
Answer:
5 11/12 cups of melon
Step-by-step explanation:
The cups of melon he puts in the fruit salad is:
Number of cups of orange melon + Number of cups of green melon
= 3 1/4 cups + 2 2/3 cups
3 + 2 + (1/4 + 2/3)
The Least common denominator is 12
5 + (3 × 1 +4 × 2/12)
5 + (3 +8/12)
5 11/12 cups
Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.
Answer:
Step-by-step explanation:
27^1/3
27 is cube root of 3
so it can also be written as (3)^3
∴ {(3)^3}^1/3
3 and 3 will get cancelled
so it will be 3^1
= 3
Answer:
I’m afraid I can’t help you. The question makes no sense because the question doesn’t explain how many students there are. It just gives the weight of the books which I assume is useless
Step-by-step explanation:
Answer:
b. 144.8
Step-by-step explanation:
When calculating the moving average estimate of an observation , each of the observations are usually computed with the same weighted . In some cases, it is beneficial to assign different weight on the observations such that the observation closer to the time period being forecast, has higher weight. This is refer to as weighted moving average technique. The sum of the individual weight in a weighted moving average technique must equal to 1.
The three-period weighted moving average forecast for period 5 = 144*0.5 + 148 *0.3 + 142 *0.2 = 144.8
