-1.3535353 is it a rational

Mathematics

Yes, it's rational.

If the digits after the decimal point terminate, then the number is

-1.3535353 = - 13,535,353/10,000,000

If they don't stop, then let <em>x</em> be the number,

<em>x</em> = -1.353535...

Multiply <em>x</em> by 100 to move the decimal point two positions to the right:

100<em>x</em> = -135.353535...

Subtract <em>x</em> from 100<em>x</em> to eliminate the fractional part, then solve for <em>x</em> :

100<em>x</em> - <em>x</em> = -135.353535... - (-1.353535...)

99<em>x</em> = -135 + 1

99<em>x</em> = -134

<em>x</em> = -134/99

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that:-

A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195.

The time will be calculated as:-

Total amount =  $195

Now the fixed consulting cost will be $60 and will be deducted from the

total amount.

Variable cost = 195 - 60 = 135

The $45 per hour charge so for $145 the time will be:-

Time = 135 / 45

Time =  3 Hours

Therefore the time spent by the repairman there will be 3 hours so the correct answer is option D.

M&lt;2=4x+12 <br> Someone help
Katarina [22]
X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!
