Let be "n" the number mentioned in the exercise.

You need to remember that:

1. In Math word problems:

- The word "times" means multiplication.

- The word "twice" indicates that something is multiplied by 2.

- "Sum" is the result of an Addition.

2. In inequalities, "Less than" is represented with the following symbol:

Then, based on the above, you know that "3 times a number" can be expressed as:

3n

And "Twice the same number":

2n

Therefore, "The sum of 3 times a number and twice the same number is less than 45" can be represented with the following inequality:

3n+2n

The answer is: Option a.

Describe the number of solutions for each system of equations graphed<br> below
abruzzese [7]
The solution of the system of equations means that following:
1- In case we are dealing with system of equations, the solution would be the point of intersection of the two graphs
2- In case we're dealing with only one equation, the solution would be the points of intersection of the graph with the x-axis

Graph (a):
The graph is for a system of equations (two lines). Therefore, the solution would be the point of intersection of the two lines.
From the graph, we can note that there is only one point of intersection between the two lines (-3,-1). Therefore, the system of equations has only one solution

Graph (b):
The graph is for a system of equations (two lines). Therefore, the solution would be the point of intersection of the two lines.
From the graph, we can note that the two lines are parallel. This means that they will never intersect. Therefore, the system of equations has no solutions

Graph (c):
The graph is for a single line. Therefore, the solution(s) would be the point(s) that make the overall equation equal to zero, i.e. point(s) of intersection with the x-axis.
From the graph, we can note that the line intersects with the x-axis only once at point (2,0). This means that the line has only one solution.

Hope this helps :)

Hello My Dear Friend!

9^y-3=8<span>
We move all terms to the left:
</span>9^y-3-(8)=0<span>
We add all the numbers together, and all the variables
</span>9^y-11=0<span>
We move all terms containing y to the left, all other terms to the right
</span>9^y=11
y=11/1
y=11

I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)
