Answer:
145
Step-by-step explanation:
To find the number of boxes to reach the goal, divide the goal amount by the box amount:

Since you can't sell .444444 of a box, you must sell 145 boxes.
Using a system of equations, it is found that 225 adult tickets were sold for the school play.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Number of adult tickets.
- Variable y: Number of student tickets.
A total of 376 tickets were sold for the school play, hence:
x + y = 376 -> y = 376 - x.
There were 74 fewer students tickets sold than adult tickets, hence:
y = x - 74.
Then:
x - 74 = 376 - x
2x = 450
x = 450/2
x = 225.

Answer:
and
Step-by-step explanation:
It is given that the normal body temperature is
.
A temperature 'x' that differs from normal by at least
is considered unhealthy. So the inequality to represent such situation is,

It can be further written as,
and 
and 
and
So the inequality to represent such condition is
and
