3 - 3 * 6 + 2 <---- Original
3 - 18 + 2 <-----First you multiply
-15 + 2 <----- Next you subtract
-13 <----- Than you add, and you get your answer
Your answer : -13
I Attatched a picture of a graphing calculator
Answer:
8
Step-by-step explanation:
Take the total, 50.35, and subtract 19.95:
50.35 - 19.95 = 30.40
Now divide 30.40 by 3.80:
(30.4)/(3.8) = 8
Therefore, Tony bought 8 markers.
Answer:
One solution
Step-by-step explanation:
First, organize the equations by moving y to the left hand side:
5x + 2y = 6, subtract 5x from both sides and we get: 2y=6-5x
3y = 2x + 9 is already done
Next, set the coeficcient of both y values equal to the least common multiple of 2 and 3 which is 6:
2y=6-5x multiply both sides by 3, 6y = 18-15x
3y=2x+9 multiply both sides by 2, 6y = 4x+18
Substitute y on both sides and we get 18-15x=4x+18
Simplify that and you get 19x=0, x equals 0, so there is one solution
