Jackie has $33, and needs to get a taxi. The cost for a taxi is a fee of $5, plus $7 per mile. Which inequality would help Jacki

Rus_ich [418]

Answer:

$5 + 7x \le 33$

Step-by-step explanation:

Given

$Base\ Charge = 5$

$Additional = 7$ per mile

$Total = 33$

Required

Determine the inequality

First, we need to determine the total cost for x miles.

$Cost = Base\ Charge + Additional * x$

$Cost = 5 + 7 * x$

$Cost = 5 + 7x$

The total cost can not exceed the amount he has, so the inequality is:

$Cost \le Total$

$5 + 7x \le 33$

Use back-substitution to solve the system of linear equations.

ludmilkaskok [199]

Step-by-step explanation:

x - y + 5z = 29

y + 2z = 4

z = 7

since z = 7 we can use this value in second equation

y + 2×7 = 4 and y = -10

now we know the value of y we can solve the first equation

x -(-10) + 5×7 = 29

x + 10 + 35 = 29

x = -11
