Answer:
<em>4 shelves</em>
Step-by-step explanation:
First you will have to subtract the one she keeps by her bed.
27 - 1 = 26 to be put on a shelf.
To find the least number of shelves needed, you will divided the total left by eight:
26 ÷ 8 = 3.25
She can fill 3 shelves completely and still have books left over. So she needs at least 4 shelves!

2/3 a mile in half an hour
3 hours=6 x 2/3
6/1 x 2/3 = 12/3
12/3 =4 miles in 3 hours
3x+2y=9
3x+2(4x-1)=9
11x-2=9
+2 +2
11x=11
X=1
Y=4x-1
Y=4(1)-1
Y=3
Answer:
{5, 7, 9, 11}
Step-by-step explanation:
Roster form just means list the elements of the set in the brackets.
It says the elements are greater than or equal to five and less than or equal to 11. So we start at 5 and end at 11.
We list {5, 7, 9, 11} because these elements follow the rule that they must be odd natural numbers. Natural numbers are the numbers you can count starting from 0 like {0, 1, 2, 3, ...}.
