This is the concept of algebra,
The fraction of children was: 3/8
fraction of adults was 1-3/8=5/8
fraction of men 3/4*5/8=15/32
fraction of women=5/8-15/32=5/32
Given that there was 140 more children than men, the fraction representing this will be:
(3/8-5/32)
=7/32
thus the total number of people will be:
1/(7/32)*140
=32/7*140
=640
the total number of people was 640
Answer:
if I'm not wrong, its x>34
Step-by-step explanation:
multiply both sides by 3
3(x - 4)/3 > 10 x 3
x - 4 > 30 (simplify)
add 4 to both sides and x > 34
Hello there! How are you today?
5a^2 + 2b^3, solve when a = 4 and b = -4
To solve for this, we must replace "a" with 4, and "b" with -4.
I will set it up;
5(4^2) + 2(-4^3)
Simplify the parenthesis (PEMDAS).
5(16) + 2(-64)
Remove the parenthesis by multiplying them by the numbers to the outside of them.
5 x 16 = 80
2 x -64 = -128
We are now left with:
80 - 128
Simplify.
-48 is your final answer.
I hope this helps!
Answer:
<h2> no, because the remainder is 126</h2>
Step-by-step explanation:
if x+3 is a factor, then -3 is a root of expression, and the remainder would be 0
calculating remainder:
72: 1,2,3,4,6,8,9,12,18,24.36,&72
18: 1,2,3,6,9, &18
18 is the greatest common factor in this problem
