Barry has 18 more marbles then heidi. if barry has 92 marbles right and solve any equation to determine the number of marbles heidi has

n= Heidi's marbles

92 - n =18   (Barry's 92 marbles - whatever Heidi has = 18 marbles difference)

92 -n +n = 18 +n   (I added n to each side)

92 = 18+n    

92 -18 = 18-18 + n   (I subtracted 18 from both sides)

74 = n    Heidi has 74 marbles

Hope this helps!

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
