Which diagram best shows how fraction bars can be used to evaluate One-half divided by one-fourth? A fraction bar labeled 1. Und
Leto [7]

Answer:

Step-by-step explanation:

The description is too ambiguous to reconstruct the diagram. You need to post the actual diagram.

That diagram is just one way to view division by a fraction. An easier way: DIVIDING by a fraction is the same as MULTIPLYING by the upside-down fraction. For example,

(1/2) ÷ (1/4) = (1/2) × (4/1) = 2

That doesn’t help you answer this particular question, though.

Which of the following graphs represents the solution set for 7(4x – 1 ) + 6x &gt; –279? PLEASE HELP
Luda [366]
First, solve the inequality:
7(4x - 1 ) + 6x \ \textgreater \  -279\\&#10;28x-7+6x\ \textgreater \ -279\\&#10;34x\ \textgreater \ -272\\&#10;x\ \textgreater \ -8
Since x is <u>greater than</u> -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.

Thus your graph is D.
