Translate

Translate the following mathematical statement into an algebraic expression or equation.
1. Nine less than the quotient of a number and 3
2. The ratio of 3 and the sum of 4 and an unknown number
3. Eighty is the product of 4 and g
4. The sum of x and 18 is 25
5. p minus 30

Correct answer:

f = a/3-9
b =  2
g =  20
x =  7
e = p-30

Step-by-step explanation:

$f=a/3-9$

$$\begin{gathered} 3\cdot b=4+b \\ 2b=4 \\ b=\frac{4}{2}=2 \\ b=2 \end{gathered}$$

$$\begin{gathered} 80=4\cdot g \\ 4g=80 \\ g=\frac{80}{4}=20 \\ g=20 \end{gathered}$$

$$\begin{gathered} x+18=25 \\ x=7 \\ x=\frac{7}{1}=7 \\ x=7 \end{gathered}$$

$e=p-30$
