Answer:
25
Step-by-step explanation:
Let x be the number of students in the class
15 is 60% of x
60% of x can be written as 0.6x
15 = 0.6x
Divide by 0.6 on both sides
25 = x
There are 25 students in the class
Hope this helps :)
Answer:
(36,72)
Step-by-step explanation:
The x (3) is half of y (6) so following that pattern (36,72) is the only option.
A.number of donuts delivered 2 hours from now.
2. Next=now +60+60
starting at 48 because 2 hours meant 2*60 = 60+60
B. number of donuts delivered 7 hours from now C
3.Next= now +420
starting at 48 because 7 hours meant 7*60 = 420 mn
C.number of donuts delivered n hours from now.
4. Next=now+60n
starting at 48 (this is obvious)
so finally,
D. number of donuts delivered 6 hours from now.
1. Next= now+ 6*60
starting at 48
Based on the given parameters, bhe true statements are: the expression has four terms, and the term -40/y is a ratio.
<h3>How to determine the true statements?</h3>
The expression is given as:
6x^3 - 8x^2 - 40/y + 21
The above expression has four terms, and the terms are:
6x^3, - 8x^2,- 40/y and 21
Also, the term -40/y is a ratio
This is so because it is a quotient of two numbers
Hence, the true statements are: the expression has four terms, and the term -40/y is a ratio, based on the given parameters
