Answer:
10.315
Step-by-step explanation:
Answer:
1. yes this is proportional
2. your table should include the following numbers
1 = 34
2 = 46
3 = 58
4 = 70
3. 12x + 22 = y
Step-by-step explanation:
multiplication is for example 10×500=5,000
division is for example 5,000÷10=500
Short answer: 98
Remark
when you have an average of 71, it's like saying that you took 4 quizzes and got 71 on all of them.
Step One
Find the total point count for the 4 quizzes.
T_4 = 71 * 4 = 284
Step Two
Create an equation that will give you the necessary point count to average 86.
284 + 5*x = 86 * 9
Why did we do this? It is because you have 9 quizzes altogether. All nine must be something that gives a point count of 86 on each quiz. You have to put together 9 such quizzes with a total count of 774.
Step three
Solve the equation.
284 + 5x = 774 Subtract 284 from both sides.
5x = 774 - 284
5x = 490 Divide by 5
x = 490/5
x = 98
You must get an average of 98 on the next 5 quizzes
