Answer:
40 students
Step-by-step explanation:
In this problem, one is given the ratio ( 8 : 3 ), since a ratio is another way of writing a fraction one can rewrite it as;
(8) represent the number of students who want to learn about magnets, and (3) represents the number of students who want to learn about magic tricks.
In the problem, it is also given that 25 more students wanted to learn about magnets compared to magic tricks. If one uses the parameter (x) to represent the factor by which the fraction
is reduced, then one can get the equation;
8x = 3x + 25
Use inverse operations to solve,
8x = 3x + 25
-3x
5x = 25
/5
x = 5
Substitute back in to find out how many students want to learn about magnets,
8x
= 8(5)
= 40
6x3+49x2+126x+104 (I just simplified it, if it is incorrect I'm sorry I didnt understand what you were asking -,^-)
Answer:
26 candies.
Step-by-step explanation:
Jimmy will have 26 candies left, because 50 - 24 = 26. Or, in other words, 24 subtracted (or ate) from 50 means 26 candies left.
Hope this helped!
Answer: Our required equation would be
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x
Answer:
10
Step-by-step explanation:
2/3 can be multiplied by 5 to equal 15ths since we can know 15 (seconds number fraction) is 5 times the originals (first numbers fractions)
This equals to 10/15 and means that with 1/15th on each 10 sandwiches can be made.
The answer gives it straight forward but explanation gets in depth
Edit: I saw your answer and yes it equals 10 but you multiply what it is a fraction of too.
2/3
x5
10/15
Hope that helps some more
