Answer 9

why?? chinese is 8 students more than spanish. x is from both. so if spanish only is 37, then spanish is = spanish only + spanish with english = 37 +x , so at that time, english is 37 +x +8
I don't know why the answer is not 18. If it is not that, I don't know how to solve

Answer 36

My baby is younger

Answer 37

yeah... hahaha

Answer 38

OOPS how do i draw this conclusion with math only

Answer 39

37+x +37+8=100

Answer 40

This is how i think of it!
There is x amount of people that Take chinese + spanish
so the +8 cant contribute there
There fore +8 must exist with Chinese only group
so 37+8=45...
Therefore
45+37+x=100, x=18

Answer 41

babies forever, hahaha...

Answer 42

A pencil manufacturer has a certain tolerance for the actual lengths of the pencils it produces. After the pencils are manufactured, a 1.1 centimeter eraser is added to one end of the pencil. The total length of each pencil must be between 12.9 cm and 13.3 cm. Write an inequality representing the possible lengths of the pencils before the erasers have been added, and then find the lengths.

Answer 43

let P be length of pencils
12.9<P+1.1<13.3
11.8<P<12.2

Answer 44

dan, you think of this. 37 is spanish only
so 37+x is spanish
this amount +8 is chinese
if 8 in both, then that 8 is spanish, right? so that 37+8+x = 45+x is spanish and the english student is 45+8 +x = 53 +x , at that moment x = 2 so the total spanish become 47 and the total english is 55 , it exceeds 100

Answer 45

chinese will be 37+8+x+8 =53+x
and solve for x we get x =2

Answer 46

so, spanish is 37+8+2= 47
english 8 more than spanish = 55
How??

Answer 47

nvm "OOOPS" i get it
