-4(7a+5)= —160

distribute the -4 on the left hand side

-4* 7a + -4*5 = -160

-28a +-20 = 160

-28a -20 = -160

add 20 to each side

-28a-20+20 = -160 +20

-28a = -140

divide by -28 on each side

-28a/-28 = -140/-28

a = 5

Answer:  a=5

-4(7a+5)= -160

=>4(7a+5)= 160 ( Removing the negative signs by switching the sides )

=>4(7a+5)/4= 160/4 ( Dividing both sides by 4 )

=>7a+5= 40

=>7a+5-5= 40-5 ( Subtarcting 5 from both sides )

=>7a= 35

=>7a/7= 35/7 ( Dividing both sides by 7 )

Therefore, a=5 (Answer)

I was going to say that you would need to change the mixed numbers into an improper fraction but then I realized that they both have the same denominator (4), meaning that in this case if the whole number outside of the fraction is bigger than the one for the other then it’s greater than regardless.

6 is greater than 5, so

5¾<6¼
