To find the value of x you need to get x by itself. First you need to subtract 5x from both sides. You will end up with -x=-12. Then you need to divide both sides by -1 to get x by itself. You get x=12
4x=5x-12
-5x -5x
-x=-12
÷-1 ÷-1
x=12
When you add 8.5+3.95+11.15, you get 23.6, that is your total money spent on lunch for that week. The correct answer is B.
3.4 - 2/3 > x
2) simplify 3.4 - 2/3 to 8.2/3
8.2/3 > x
3) Simplify 8.2/3 to 2.733333.
2.733333 > x
switch sides
3 + 0.45*M<=8,40. Notice the equal, because you may use all the money. Then, rearranging: M<=(8.40-3)/0.45= 12, so M<=12. Now, obviously time is positive, so you may end saying 0<=M<=12, with M=0 meaning no call! :)
Answer:
Step-by-step explanation:
Since all sides of a triange equal 180 degrees you would add up all the givin sides and subtract them by 180 and you would get your answer.
