5p-4p-8=-2+3
Combine like terms
p-8= 1
Add 8 to both sides to isolate p
p=9
Final answer: 1 solution only, p=9
so if x = -1, let's plug that in the second equation
-5(-1)+y = 5
5+y = 5
y = 0
The probability that the major of one student that is selected at random is engineering can be calculated by the total number of engineering major divided by the total number of students
p = engineering / total students
p = 300 / ( 300 + 700 + 500)
p = 0.2 is the probability of the major of one student is engineering
Let s equal the cost per shirt.
First, we are going to multiply the cost of one shirt to the sale of 25%
0.25s
Second, we are going to multiply by 3 since you are buying 3 shirts.
* 3
Put together.
0.25s * 3
Best of Luck!
