Which equation should be used to solve this problem?
bob has 10 more marbles than larry. togther they have a total of 29 marbles. how many marbles does larry have?
let l = the number of marbles larry has.

B has 10 more than L
b is 10 more than L
B=10+L

together they have 29
B+L=29

B=10+L
10+L+L=29
10+2L=29
minus 10
2L=19
L=9.5
what
how does larry have 9 and 1/2 marbles
who has 1/2 of a marble

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
