Hey there!
We can solve inequalities just like equations. There is only one difference though. If you ever multiply or divide both sides by a negative number, you "flip" the inequality sign.
First, let's undo the parentheses.
2x-24+24<4x+20
We simplify.
2x<4x+20
We subtract 4x from both sides.
-2x<20
We divide both sides by -2 (we will need to flip the inequality sign).
x>-10
I hope this helps!

Step-by-step explanation:
Let
x -----> the number of days
y ----> the number of candies remained
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
In this context, the x-intercept is the number of days that have passed when the amount of candy remaining is equal to zero.
The X intercept represents the number of days it takes for all the candies to be gone. When the line goes through the X-axis (X intercept), it means that there are no candies remaining in the bowl.
In the context of Felipe's bowl of candies, the X intercept on a graph represents the number of days it takes for all the candies to be gone. Essentially, the X intercept is when the Y value (in this case, the number of candies remaining) hits zero.
This is because the X-axis often represents time in such scenarios, and when the graphed line crosses, or 'intercepts' the X-axis, it means the count of what is being measured (candies here) has become zero. So, if the graph showed that the X intercept was 5, it would mean all of the candies were eaten within 5 days.

Answer:
$11
Step-by-step explanation:
we can set up an equation to answer the question. a first payment of 28 plus some amount monthly for a year equals 160. so,
12x + 28 = 160
subtract 28 from both sides
12x = 132
divide by 12 and we get our answer
x = 11
