Please help! My max is 17 points that how much they gave me!!
Firdavs [7]
The answer is 29. If you put it in an equation, it looks like 90=(x*3)+3. If you -3 from each side, you get 87=x*3. Divide each side by 3, and you get x=29.

4 students is what percentage of 20 students?2 doctors is _____% of 25 doctors.
Ray Of Light [21]

In both cases, we can use a rule of three.

<h2>First part</h2>\begin{gathered} 20\text{ students}\rightarrow100\text{\%} \\ 4\text{ students}\rightarrow x \\ x=\frac{4\text{ students}\cdot100\text{\%}}{20\text{ students}} \\ x=\frac{4\cdot100\text{\%}}{20} \\ x=\frac{400\text{\%}}{20} \\ x=20\text{\%} \end{gathered}

Therefore, 4 students correspond to 20% of 20 students in total.

<h2>Second part</h2>\begin{gathered} 25\text{ doctors}\rightarrow100\text{\%} \\ 2\text{ doctors}\rightarrow x \\ x=\frac{2\text{ doctors}\cdot100\text{\%}}{25\text{ doctors}} \\ x=\frac{2\cdot100\text{\%}}{25} \\ x=\frac{200\text{\%}}{25} \\ x=8\text{\%} \end{gathered}

Therefore, 2 doctors correspond to 8% of 25 doctors in total.
