Simplify 72/3 - 5(8.8 - 6) + 9

First: combine the terms in parenthesis.

72/3 - 5(2.8) + 9

*Combine the outer term with the term in parenthesis.

72/3 - 14 + 9

72/3 - 5

*Make the whole number, 5, a fraction - place 5 over 1.

72/3 - 5/1

Sec: find the greatest common denominator which is, 3.

72/3 = x/1 - 5/1 = x/1

Third: multiply the denominators & their corresponding numerators with the missing values to get the greatest common denominator.

(1)(72/3) = x/1 - (3)(5/1) = x/1

(72*1/3*1) = 72/3 - (5*3/1*3) = 15/3

*Combine the fractions with the same denominators.

72/3 - 15/3

57/3

19

yah. the ans is 19
first divide 72 by 3, which would give 24. then substract 6 from 8.8 and multiply the ans by 5, which would give 14. then it will look like 24 - 14 + 9. which is equal to 19

you're at a loss for words. If the context of the sermon became into homosexuality-then that's very nicely to enhance out only that section that speaks to homosexuals. The sermon or the element would be topical. yet while the sermon became into expository and this passage became into the crucial topic then all of it would be used. while a sermon became into on tithing, you do no longer use verses approximately ingesting wine. no person is going to hell for being divorced, or gay. One only is going to hell for rejecting God. All homosexuals reject God, even people who declare to be priest or ministers. God by no ability condemns all people because of the fact some preachers do no longer know the thank you to exact build a sermon, or supply it. God condemns human beings for rejecting Him-era.

nothing is free :) you must process division and multiplication, later - and +. and first solve parenthesis.

72/3 ........ -5 ....... (8.8 ........ -6) ....... +9
