Which is longer, 1/4 of line A or 1/4 of line B? Explain.

rewona [7]

Answer:

1/4 of Line A is SMALLER than 1/4 of line B.

Step-by-step explanation:

Here, two given lines are A and B.

Now,as we can see, From the two lines Line B is LONGER.

⇒ Length of line A < Length of Line B

Now as we know if we MULTIPLY or DIVIDE an inequality by a same positive number on both the sides, then the SIGN DO NOT CHANGE.

Here, divide both sides of the equation by 4, we get:

$\implies \frac{\textrm{Length of line A}}{\textrm{4}} < \frac{\textrm{Length of line B}}{\textrm{4}}\\\implies \frac{1}{4}({\textrm{Length of line A}}) < \frac{1}{4}({\textrm{Length of line B}})$

Hence, 1/4 of Line A is SMALLER than 1/4 of line B.

PLEASE HELP!!!! I know the answer, but I don’t know how to solve the problem!!!

nevsk [136]

To start you need to get rid of the denominator so you add -4 by 8 to get 4 then multiply both sides by 4 to remove the denominator giving you -8= 5-y1. After that subtract 5 from both sides giving you -13= -y1, dividing by -1 you then get y1= 13
