Answer:
The number is 10
Step-by-step explanation:
3x-8=22
3x=30
x=10
Answer:
x = 6
y = 0
Explanation:
−2x+y=−12;3y−2x=−12
Rewrite equations:
−2x+y=−12;−2x+3y=−12
Solve −2x+y=−12 for y
−2x+y=−12
−2x+y+2x=−12+2x(Add 2x to both sides)
y=2x−12
Substitute 2x−12 for y in −2x+3y=−12
−2x+3y=−12
−2x+3(2x−12)=−12
4x−36=−12 (Simplify both sides of the equation)
4x−36+36=−12+36 (Add 36 to both sides)
4x=24
Divide both sides by 4
4x / 4 = 24 / 4
x = 6
Substitute 6 for x in y=2x−12
y=2x−12
y=(2)(6)−12
y=0 (Simplify both sides of the equation)
If every single student met one an another, then you would hear 90 hi's. Since there are 45 different combinations of 2 students meeting another, and since there are 2 hi's each meeting, there would be 90.
I hope that this helps.
