The answer is C 38.All the numbers add up to 190 and 190 divided by 5 is 38
Answer:
1. .........................................
- 2x = 3
- x = 3/2 Fraction
- x = 1.5 Decimal
2. ..........................................
- 5y = 3
- y = 3/5 Fraction
- y = 0.6 Decimal
3. ..........................................
- 0.3z = 0.009
- z = 0.009/0.3 = 9/300 = 3/100 Fraction
- z = 0.09 Decimal
Using algebra
n and n+2 are the integers
n*(n+2)=288
n^2+2n=288
n^2+2n-288=0
288=2*2*2*2*2*3*3=(2*2*2*2)*(2*3*3)=16*18 and 18-16=2
factor(n+18)(n-16)=0
n+18=0
n=-18
n+2=-16
this is one solution
n-16=0
n=16
n+2=18
this is another solution
as you can see, it's just a matter of factoring 288using arithmetic...√288=16.97≈1716 and 18 are the integers (as well as -16 and -18)
