The answer should be 42.
Since there are 60 questions in the test and she managed to answer 70% of the questions correctly, that means that she answered 70% out of 60 questions correctly.
So you need to calculate how much 70% out of 60 is. Since % is always measured on a base from 0 (%) to 100(%), then 70% is equal to the fraction 70/100, simplified to 7/10. To know how much 7/10 out of 60 is,you just multiplie them and your answer will be 42.
I hope this helps you forward.
Answer:
x = -6
Step-by-step explanation:
We recognize that 25 = 5^2 and also 125 = 5^3, thus we can write:
<em>Now we can use the property of exponents [
] to simplify it:</em>
We equate the exponents (since we have similar base) to find the value of x:
4x + 6 = 3x
4x - 3x = -6
x = -6
