Bill=parts+labor
labor=31 times hours or h
parts=125
bill=311


311=125+31h
minus 125 both sides
186=31h
divide both sides by 31
6=h

6 hours

Write the if/else statement as the conditional expression that performs the same option result = x < y ? x * 5 : a b;
Semenov [28]

The conditional statement is

if x < y:

  result = x * 5

<h3>How to write the if/else statement as the conditional expression that performs the same option?</h3>

The statement is given as:

result = x < y ? x * 5

The above means that,

the variable result is assigned  x * 5 if x < y

So, the conditional statement is

if x < y:

  result = x * 5

If R is between P and Q, find the value of x and PR. PQ=17, PR=5x+2, RQ=x^2-1
vodka [1.7K]

The value of x will be2.217 and PR will be 13.085 units.

<h3>What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given that,

Line PQ consists of two segments PR and RQ

So,

PQ = PR + RQ

17 = 5x+2 + x² - 1

x² + 5x  - 16 = 0

The roots of the equation will be

x = [-5 + √(25 + 64) ] ÷ 2

x = 2.217

Now,

PR = 5(2.217) + 2 = 13.085

Hence "The value of x will be2.217 and PR will be 13.085 units".
