Step-by-step explanation:
Percentage increase = (279 - 180)/180 x 100% = 55%
this is a topic on percentage. the above question requires a use of a kind of formula if you wish to explore more into this topic you can give me a follow on Instagram (learntionary) I've already posted some notes on this topic and will be doing more on others and also I'll be providing tips on some topics as well!
So first you would divide the 10 by 2
-4=12p+5
Then you subtract the five from both sides to try to isolate the variable p
-4=12p+5
-5 -5
You then divide both sides by 12 to solve for p and simplify
-9=12p
(-9/12)=(12p/12)
-3/4=p
Graph is attached.
Based on the graph (with height on the independent axis and weight on the dependent), there is a negative correlation between height and weight; as the height increases, the weight decreases.
If we were to graph this with weight on the independent axis and height on the dependent, there would still be a negative correlation.
Without knowing the number of students she has, you will not be able to answer the question correctly. There are 12 eggs in one dozen. 12 x 7 dozen = 84 eggs.
You still need to know the number of students.
