Answer:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.
It is instructed to subtract (2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).
So, First we will do the sum of the three given polynomials,
Sum =(a+3b−4c)+(4a−b+9c)+(−2b+3c−a)
=(a+4a−a)+(3b−b−2b)+(−4c+9c+3c)
=4a+8c
Now, we can perform the subtraction,
∴ Required difference
=(4a+8c)−(2a−3b+4c)
=4a+8c−2a+3b−4c
=2a+3b+4c
Answer:
80% probability
Step-by-step explanation:
Since there are 8 yellow marbles out of 10 marbles in all, that equals 8/10 which is the percent of 80.
