Answer:
27
Step-by-step explanation:
<h2><u>Number of documents</u></h2>
jacob copies 30% of a document which is 8 pages
we can solve this using cross multiplication
30 % : 8
100% : x
30%x = 100%*8
30% x = 8
x = 8/ 30%
x = 26.667
to 2sf
<h3><u>number of pages in the documents 27 </u></h3>
<u />
Step-by-step explanation:
Given,
x = y - 3
Also,
6(y - 3) = 3y + 6
6y - 18 = 3y + 6
6y - 3y = 6 + 18
3y = 24
y = 24/3
y = 8
x = 8 - 3
x = 5
Therefore, the first number is 5 and the second number is 8.
A = 30
B = 41
C = 70
A < B + C
30 < 41+70 ==> 30 < 111 (TRUE)
B < A + C ==>
41 < 30 + 70 ==> 41 < 100 (TRUE)
C < A+B
70 < 30 + 41 ==> 70 < 71 (TRUE)
Yes, can!

Answer: See explanation
Step-by-step explanation:
Let the possible number of CDs that she could buy be represented by x. Then, the equation can be represented as:
80 - 18x ≤ 20
80 - 20 ≤ 18x
60 ≤ 18x
x ≤ 60/18
x ≤ 3.33
The highest amount of cd that she can is 3 or less.
