I think what they are looking for in section A) is <u><em>4x+10 </em></u>
and in section B) <u><em>18</em></u>
Step-by-step explanation:
In order to get the answer for A you must add like terms. Each side has a x meaning x multiplied by 4 or 4x then you have 5 on each length meaning 10 so when you put those together you get <em><u>4x+10.</u></em>
In order for you to find Bs solution you subtract 10 from 62 which is 52 then divide 52 by four for each x and 52 divided by 4=13 so<em><u> x=13</u></em> and then you add 5 to 13 to get 18 which is the length
Shana drew 48 times and pulled a green marble 8 times, so the fraction of green marbles in the bag is about 8/48. Multiply that by the total number of marbles in the bag and you get the total number of green marbles in the bag.
