Step-by-step explanation:
1- 6(x+8)=5x+4. First calculate the brackets.
2- 6x+48=5x+4 (multiply the number in front of the brackets with the numbers in the brackets) so 6×X= 6x and 6×8= 48
3- 6x-5x= -48+4 put the numbers with x on the left hand side and the others on the right hand side. (when moving from side to the other side you convert + into - or reversed)
4- x= -44 now work out the sums and then you get x
Note that Cheryl wants to find the number of hours <u>seventh grade boys and girls</u> spend on homework each week.
There are multiple causes of a biased sample. Two of the most obvious ones I find are:
1. She's surveying <u>girls</u>, but she is trying to get data on the number of hours <em>all</em> seventh graders (boys <em>and</em> girls) spend.
2. She's surveying 50 girls from the <u>entire school</u>, although she is trying to get data on seventh graders only.

Answer:
a=5/4-1/3 Then multiply by 12
а=12*5/4-12*1/3
a=3*5-4*1
a=15-4
a=11
