Brian was thinking of a number. Brian doubles it and adds 5.1 to get an answer of 91.3. Form an equation with x from the information.

Step-by-step explanation:

x would represent his number. in this case, you double x, because he doubles his number, and then you add 5.1. to solve for x, aka find his original number, you can subtract 5.1 from both sides and then divide by 2. hope this helps!

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
