Answer:
20 riders can ride per minute.
Step-by-step explanation:
The picture says to divide to find the number of riders. If we apply this here, we can see that 1200 ÷ 60 is 20.
The reasoning behind this is:
There are 60 minutes in an hour.
If the park ride lasts a minute, then the ride can have 60 rides per hour.
The question states that the ride can have up to 1200 riders per hour, so you need to divide 1200 by 60.
1200 ÷ 60 = 20.

(1/3)*(1/4)=1/12 cups of sugar
<em><u>Option B</u></em>
The result of addition is 2y = 24
<em><u>Solution:</u></em>
Given that we have to add the equations
<em><u>Given equations are:</u></em>
5x - y = -1
-5x + 3y = 25
We have to add both equations
This is similar to adding numbers. i,e 1 + 2 = 3
<em><u>For adding variables,</u></em>
When adding or subtracting terms that have exactly the same variables, you either add or subtract the coefficients, and let the result stand with the variable.
Example: 2x + 3x = 5x
Keeping this in mind, let us add the given equations
5x - y = -1
-5x + 3y = 25
----------------------------
0 + 2y = -1 + 25
[ 5x and -5x cancels each other. Combine -y and 3y which gives 2y]
2y = 24
Thus Option B is correct
Answer:
B
Step-by-step explanation:
i am not sure
Inverse of a function is also a function, if and only if the function is One - to - One. This means no y value occurs in the range of the function more than once.
If we observe the given options, we can see option B, C and D have some repeated values of y. Only the function in option A is one to one. Hence the inverse of function given in option A will also be a function.
So, the answer to this question is option A
