2:3 is the ratio of students who bring their lunch to the number of students who do not
Answer:
the number is 24
Step-by-step explanation:
10 less than two thirds the number is one fourth the number
Let the unknown number be x
two third of the number is 
10 less than two third the number becomes
one fourth the number becomes 
10 less than two thirds the number is one fourth the number
We need to solve for x
LCD is 3*4 = 12
Multiply the whole equation by 12
8x - 120 = 3x
add 120 on both sides
8x = 3x + 120
Subtract 3x on both sides
5x = 120
divide by 5 on both sides
x= 24
A ratio is not multiplication, so I'm just going to throw that out there first in case any other answers trip you up.
9:2 is the correct answer because there are 9 sandwiches for 2 people.
Answer:
m<7 = 61
Step-by-step explanation:
These angles (<7, and <8) are adjacent to each other (they are next to each other), therefore they are supplementary (add up to 180).
180 - 119 = m<7
Answer:
6 years and 1 month
Step-by-step explanation:
A= Pe^rt
Since you need to find the double A=2P
2P=e^0.1132t
0.1132t=ln 2
0.1132t=0.693
t= 6.12

ps: I think this is right but I'm not sure I had the same problem and I got this.
