The compound inequality that gives the normal range for the pH values of lemon juice is given by:
<h3>What is a compound inequality?</h3>
A compound inequality is modeled by:
Which means that x is greater than a and less than b. In this problem, the pH is greater than 1.5 and less than 4, hence the inequality is given by:

Answer: -28
7/2=3.5
3.5x-8=-28
Answer:
<h2>
X = 4.5</h2>
Step-by-step explanation:
So we have two equations.
y=35x+40
y=40x+17.5
We want to find the coordinates in which they intersect.
BUT They never intersect, They are parallel to each other leaving us with a
NO SOLUTION
When you are trying to solve for x you want to get rid of the y's and simply put on your paper: 35x+40 = 40x+17.5
Then you distribute, in which I am not going to show because that too many steps lol. But you'll get:
x=4.5
