5≤1e+ .25p
E represents erasers and p pencils
Answer:
If you cube the numbers in the left column, you get the numbers in the right column! We can figure this out by understanding that 1^3 = 1, 3^3 = 27, and 6^3 = 216. Then it all falls into place!
1 -> 1
2 -> 8
3 -> 27
5 -> 125
6 -> 216
11 -> 1331
8 -> 512
10 -> 1000
7 -> 343
14 -> 2744
p -> 
-> q
The 9 is in the tenths place
The 8 is in the hundredths place
The 7 is in the thousandths place.
Well since each shelf holds 40 you would add up the two shelves to 80 then add 5 on one shelve to get 85. Since he has room for 40 you would subtract 5 and get 35
(I'm assuming the numbers after the variable "m" are the exponents)
21

- 7

+ 49m = 7m(3

-

+ 7)
Whenever you see a term before a set of parentheses, it is indicating that when that term is divided from each term in the expression it is equal to, the quotient is whatever is in the parentheses. When you multiply every term in the expression in the parentheses by the term outside the parentheses, the product would equal the expression on the left.
Hopes this helps!
*Btw, decreasing order of exponents means what it says. It's basically asking you to list your terms from greatest exponent to lowest exponent.
