X= -2/5 + y/5 solve for x by simplying both sides of the equation, then isolating the variable
-15x-6y+24y+6x
-9x-30y
I think
Answer:
x = -5
Step-by-step explanation:
x+7=2
-7 | -7 -7 from both sides
x= -5
Answer:
Probability that both of them use it = 0.3945
Step-by-step explanation:
Given:
Student use app = 63%
Number of chosen student = 2
Computation:
Assume total number of student = 100%
So, probability that both of them use it.
⁶³C₂ / ¹⁰⁰C₂

Therefore, probability that both of them use it = 0.3945
