-\frac{4}{6} + -\frac{7}{9} = -\frac{13}{9}

Step 1: Cancel 4/6 and change to 2/3.

= -\frac{2}{3} - \frac{7}{9}

Step 2: Adjust Fractions based on the LCM.

The LCM of 3 , 9 : 9

= -\frac{6}{9} - \frac{7}{9}

= \frac{-6 - 7}{9}

Step 3: Subtract the numbers : - 6 -7 = -13

= -\frac{13}{9}

Follow ALL instructions for this assignment. In 3-5 sentences answer the question: What does the word similar mean and how does
vova2212 [387]

Answer:

the word similar means when to things are alike, it compares to congruent because congruent means thing are in harmony.

Things I would say are similar is a blanket and a sheet because they both provide coverage and warmth.

If I said things are similar it is because they are alike in meanings, or appearence.

I would use similar over congruent because congruent isn't a word you hear often. When you do hear it is mostly used to talk about angles and lines.

R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
