Answer:
Nicole is now 15 years old
Christine is now 5 years old
Step-by-step explanation:
x = age Nicole
y = age Christine
x = 3y
x+5 = 2×(y+5) = 2y + 10
3y + 5 = 2y + 10
y + 5 = 10
y = 5
x = 3y = 3×5 = 15
Consecutive intergers are 1 away from each other so
numbers are
x,x+1,x+2
average is found by adding the numbers up and dividng the total by the number of numbers you have
so we add x+x+1+x+2 up and divide it by 3 (3 numbers)
x+x+1+x+2=x+x+x+1+2=3x+3
(3x+3)/3=53
[3(1x+1)]/3=53
3/3 times 1x+1=52
1x+1=53
subtract 1 from both sides
x=52
subsitute
x+1 is the second
x+2 is the third
x+1=52+1=53
x+2=52+2=54
numbers are 52,53,54
X=1.5 also report other dude he put anything
