That's an easy one! The year would be Monday Janurary 27th, 3000 and it would be the year of the monkey!
Answer:
x=2y-3
Step-by-step explanation:
x=Jan's age
y=Tritt's age
If alonzo is x then the equation is
x + (x +3) + 2(x + 3) = 57
Which equals
x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12
This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old
Answer = 15 years old
With rational coefficients (a, b and c), if one zero is rational, that means the discriminant is rational. We can conclude that the other is also rational.
Step-by-step explanation:
x=2y-5 - equation 1
4x+3y=-9 -equation 2
Replace equation 1 in equation 2
4(2y-5)+3y=-9
8y-20+3y=-9
11y=-9+20
11y=11
y=11/11
y=1
If y=1, therefore x=2(1)-5=-3
x=-3,y=1
