Answer:

$x=14$

Step-by-step explanation:

Similar shapes have proportional corresponding sides. So,

$\dfrac{AB}{PQ}=\dfrac{BC}{QR}=\dfrac{CD}{RS}=\dfrac{DE}{ST}=\dfrac{EA}{TP}$

Substitute all lengths:

$\dfrac{4}{28}=\dfrac{3}{21}=\dfrac{5}{35}=\dfrac{3}{21}=\dfrac{2}{x}$

Therefore,

$\dfrac{2}{x}=\dfrac{1}{7}\\ \\x=14$

Your EZ Pass account begins with $80. It costs you $4/day. Write an equation

vivado [14]

Answer:

The equation is $A(d) = 80 - 4d$

Step-by-step explanation:

Linear function:

A linear function for the amount of money in an account after t days is given by:

$A(d) = A(0) - md$

In which A(0) is the initial value and m is the daily cost.

Your EZ Pass account begins with $80. It costs you $4/day.

This means that $A(0) = 80, m = 4$

$A(d) = A(0) - md$

$A(d) = 80 - 4d$
