<h3>How to solve arithmetic?</h3>

Arithmetic can be solved by using PEMDAS rule.

P = parenthesis

E = exponential

M = Multiplication

D = division

A = addition

S = Subtraction

Therefore,

12 - 4 + 5x² = 20

12 - 4 + 5x² = 20

8 + 5x² = 20

5x² = 20 - 8

5x² = 12

x² = 12 / 5

x = √2.4

Answer:

The ratio of tables that are booths to the total number of tables = $\frac{72}{108}$

Step-by-step explanation:

The number of tables in a restaurant, p = 108

The number of table that are booths, q = 72

Then, the ratio of tables that are booths to the total numbers of tables = $\frac{q}{p}$

= $\frac{72}{108}$

Four less than nine times a number is one hundred twenty-two. Find the original number.

Tasya [4]

Answer:

The number is $14$

Step-by-step explanation:

Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.

Our number is z, then the left hand side of the equation is 9z-4.

The right side of the equation is 122. Then the complete equation is $9z-4=122$ . Add 4 in both sides to get $9z=122+4=126$ . Now, divide by 9 in both sides to get $z=\frac{126}{9}=14$
