Answer: Write the expression as:

" 70 $\frac{32}{100}$ +
2 $\frac{1}{10}$ * 2 $\frac{7}{10$ − 18a " ;
______________________________________________________
or; write as:
______________________________________________________
" 70.32 + (2.1) * (2.7) − 18a " ;
______________________________________________________

To simplify:
______________________________________________________

Using "PEDMAS" (the "order of operations") ;

the "multiplication" comes first;

So: → "(2.1) * (2.7) = 5.67 " .

And rewrite:
______________________________________________________
" 70.32 + 5.67 − 18a " .

Now: " 70.32 + 5.67 = 75.99 " ;

So, we can the final simplified expression as:
______________________________________________________
" 75.99 − 18a " ;

or; write as: " 75 $\frac{99}{100}$ − 18a " .

HELP ME ASAP PLEASE I'LL GIVE U BRAINIEST Recall your studies of geometry (or another math course) and algebra. Choose one that

guajiro [1.7K]

This is what I put in my response

For me I thought that algebra was better. I loved algebra I mean math is math somethings in math are hard, somethings are easy, sometimes in math you will come across something that seems impossible. Sometimes you will fly thru but, what makes the journey bearable is the people around you. Why I think algebra is better is because of the people that were in math course with me and my teacher because. The teachers make all the difference.
