Multiply numerator and denominator by the same number - 50/100.
Answer:
3 * (x + 7)
Step-by-step explanation:
Mark number as x
Then the sum of a number and seven is x + 7
Three times x + 7 can be written as
3 * (x + 7)
Parentheses mean that we first add x and 7 and then multiply their sum by 3
Alternatively you can write it as 3x + 21, since
3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21

<h2>
a₂₁ = 188</h2>
Step-by-step explanation:
The n-th term of an arithmetic sequence: 
so:
The total number of fossils at the museum is 25. If you divide 15 by 60%, you get 25. To check to see if that makes sense, multiple 25 by 60% and you should get 15. By getting 15, you now have 60% of the total fossils at the museum, proving that the total amount of fossils is 25.
