For this case we must find the solution of the following expression:
If we isolate a term and we equate to zero, we have:
Subtracting 7 on both sides of the equation we have:
Thus, the solution of the expression is given by:

I am pretty sure that the answer is 4/5, hope this helped :)
Step-by-step explanation:
Quesion 1
The cost of one chair can be found by dividing the cost of the total chairs by the number of chairs
hence, cost per chair= 150/50= $3 per chair
Question 2
let us find the number of walnuts per bag
= 330/6
=55 walnuts per bag
hence in two bags there will be 55*2= 110 walnuts
Question 3
Option D is an example of a unit rate.
The unit rate is defined as the cost of one unit of an item, or the value that represents a unit of a quantity... D 18 miles driven in a week
Answer:
Discrete variable
Step-by-step explanation:
We are given the following in the question:
Variable:
Total number of points scored in a football game
Discrete and continuous data:
- Discrete data is the data that can be expressed in whole numbers. They cannot take all the values within an interval.
- Discrete variables are usually counted and not measured.
- Continuous variable can be expressed in fractions and can take any value within an interval.
- Continuous variable are usually measured and not counted.
Since, total number of points score in a foot game are expressed in whole numbers and cannot be expressed in decimals, they are discrete variable. They cannot take all the values within an interval and they are usually counted.
Thus,
Total number of points scored in a football game is a discrete variable.
