Answer:
The correct answer is y = 9
Step-by-step explanation:
It is given that,
12/(4y + 6) = 2/7
<u>To find the value of y</u>
12/(4y + 6) = 2/7
By cross multiplying,
12 * 7 = 2 * (4y + 6 )
84 = 8y + 12
8y + 12 = 84
8y = 84 - 12
8y = 72
y = 72/8 = 9
y = 9
Therefore by solving the given expression we get the value of y = 9
Do you have a picture of the problem
Not this riddle again
3 kids
what you are supposed to do is factor 72 and see their sums
1+1+72=74
1+2+36=39
1+3+24=28
1+4+18=23
2+2+18=22
1+6+12=19
2+3+12=17
1+8+9=18
2+4+9=15
2+6+6=14
3+3+8=14
3+4+6=13
notice that all the sums are different except for the 2 that add to 14
since there is not enough info, we can conclude that the sum was 14 and that the ages is either 2,6,6 or 3,3,8
after he says, "the youngest is called justice"
now we know there is a youngest
it cannot be 3,3,8 because 3 and 3 are both youngest
therefor the ages are
2,6 and 6 years old
Fourth root (3/2x)
= [fourth root {3*(2x)^3} / {2x * (2x)^3}]
= [fourth root (3*8x^3}) /(2x)^4]
= [fourth root (24x^3)] / 2x
answer is B. second one
