KL = LM                         To find the measures of KL
8x-5 = 6x+3                
-6x      -6x                               8(4) - 5
___    ___                                32 - 5
2x - 5 = 3                                   27
    +5    +5
    __    __                        To find the measure of LM
                                                  
2x = 8                                        6(4) + 3
---   ---                                         24 + 3
x = 4                                               27

The answer is x=4. 
set the equations up: 8x-5=6x-3
Subtract 6x from one side and then the other side 2x-5=3 
Add 5 from one side and then the other 2x=8
Divide 2 on each side which gets you x=4

Sladkaya [172]

Answer:

The time it took until 2 inches of rain fell is 8 hours

Step-by-step explanation:

You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x

To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:

2= 0.25*x

Solving:

\frac{2}{0.25}=x

8 = x

So, remembering that the amount of time it had been raining, x, is expressed in hours, <u><em>the time it took until 2 inches of rain fell is 8 hours</em></u>.

winnie wrote the following riddle i am a number between 60 and 100 my ones digit is two less than my tens digits im a prime numb
Lina20 [59]
<span>The answer is that 79 IS NOT correct because the riddle says "my ones digit is 2 LESS than my tens digit.." and 79 has 7 in tens and 9 in ones which means the ones digit is 2 MORE than the tens digit.

To solve 
x has to be more than 60 and less than 100
the primes between those are 61,67,71,73,79,83, 89, 97
97 is two less in the ones than in the tens so it completes all of the requirements of the riddles therefore, 97 is the answer.</span>
