A restaurant has 18 tables and 54 chairs. The

luda_lava [24]

Answer:

The ratio is 1:3

Step-by-step explanation:

Let

x -----> the number of tables in the restaurant

y ----> the number of chairs in the restaurant

we know that

To find out the ratio of tables to chairs in the restaurant, divide the number of tables by the number of chairs

we have

$x=18\ tables\\ y=54\ chairs$

so

The ratio is equal to

$\frac{18}{54}$

Simplify

Divide by 18 both numerator and denominator

$\frac{1}{3}$

therefore

The ratio is 1:3

Answer:

aₙ = 31n - 5

Step-by-step explanation:

The terms of your sequence are.

26, 57, 88, …

This is an arithmetic sequence, because there is a constant difference of 31 between consecutive terms.

The explicit formula for the nth term of an arithmetic sequence is

aₙ = a₁ + d(n - 1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,

aₙ = 26 + 31(n - 1) = 26 + 31n - 31

aₙ = 31n - 5

The explicit rule for the arithmetic sequence is aₙ = 31n - 5.
