To find the range of these scores, we must take the largest scores and subtract the smallest from it.
The largest score is 99, and the smallest score is 80.
99 - 80 = 19
The given expression is:
So, there are two terms in the expression
1)
2) -5
The constant term is -5.
The co-efficient of
is 4.
The answer is 11. Hope this helped.
Answer:
A two-step equation is something like:
A*X + B = C
In this case, like in a linear equation, we have only one solution that can be found as:
A*X = C - B
X = (C - B)/A
In the case of a two-step inequality, we have something like:
A*X + B > C
Solving this we get;
A*X > C - B
X > (C - B)/A
In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.
That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.
