We have the expression:
And we need to solve this for x.
Let's solve this expression and then see which of the options is the correct one.
The first step to solve this is that we need for the two sides of the equation to have the same base. (the number 5 on the left side is the base, so we need to also have a 5 as the base on the right side).
We do this by noting that:
We know that 25 is equal to 5 squared (because 5x5 is 25)
So the first step is to substitute 25 for 5 squared:
Since we have the same base on both sides (5), we follow the rule:
• If we have the same base on both sides of an equation, the exponents have to be equal
Thus, the second step to solve is to equal the exponents:
Finally, to solve this equation for x, we just need to add 1 to both sides to get rid of the -1 on the left side:
And the third step is:
As we can see, these three steps are represented in the third option In which we get the same result of x=3.
Answer: x=3
You need to first multiply 100 by 42 then divide by 15
Dispenser C is your answer
16/25 x 4/4 = 64/100
64/100 = 0.64, or 64%
Your answer is Dispenser C

Answer:
John have $36 and he should give $48 to his brother for both to have equal money.
Step-by-step explanation:
Given that,
amount of money John have = $84
amount of money John's brother owed to her friend = $12
$12 of the $84 is going to his brother's friend, that leaves $72 for John and his brother.
If they are to finish with the same amount, then each should have half of the John's money after he paid $12
So,
72/2
= 36 each
but since John's brother have to give 12 rupees in debt so
36+12
= $48
So John should have $36 and he should give $48 to his brother.
