Answer:
24
Step-by-step explanation:
The LCM or least common multiple of these numbers is 24
To get 24, you list all the multiple of these numbers until they all share at least one
So
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, <u>24</u>
6, 12, 18, <u>24</u>
8, 16, <u>24</u>
They all share 24 so this is the LCM
Hope this helps

Answer:
Washer = $616, Dryer = $308
Step-by-step explanation:
When something is twice the cost of something else but add up to be a total number that means 2/3rds is one item and 1/3 is the other.
924 / 3 = 308
308 * 2 = 616
308 + 616 = 924
Answer:
The answer to your questions is: 25 new teachers
Step-by-step explanation:
Data
# of students = 2000
ratio = 3:80 teachers to students
New teachers = ?
Process
I suggest to use rule of three to solve this problem
3 teachers ---------------- 80 students
x ---------------- 2000 students
x = (2000 x 3) / 80 = 75 teachers
Number of initial teachers = 75
The ratio change to 1:20
1 teacher ------------------- 20 students
x ------------------- 2000 students
x = (2000 x 1) / 20
x = 100 teachers
Number of new teachers = 100 - 75 = 25
Answer:
25.5
Step-by-step explanation:
first find the area od the rectangle than the triangle.
to find the area count the number of squares and use A=b*h
than do the same for the triangle using A=.5*b*h
15=3*5
10.5=.5*3*7
10.5+15=25.5
the equation is 2x-1 right so all you have to do is plug and go
2x-1
2x10-1
20-1
19
so your answer would be A)19
