Question

Solve the inequality.
a + 8 – 2(a – 12) > 0
a. a < 32
b. a > –16
c. a < –16
d. a > 32

Answer 1

sorry didnt see the notification a+8-2a+24>0 how do i isolate a's?

Answer 2

you didnt

Answer 3

no but how can i

Answer 4

i honestly dont know i jst start this

Answer 5

To isolate variables you need to get variables on one side of the sign numbers on the other after i distribute combine like terms get a's with a's and numbers (without a variable) with numbers without a variable

Answer 6

so 8+24?

Answer 7

So A)

Answer 8

yes now did you guess or do you know how to do it?

Answer 9

i Guessed i wont lie

Answer 10

good guess lol ill walk you through on how to do it

Answer 11

ahahah Thanks

Answer 12

a+8-2(a-12)>0
first you need to distribute the -2 (multiply everything in the parenthesis by -2)
so a+8-2a+24>0 (-12 becomes a positive 24 because you multiplied by -2 and two negatives make a positive)
now you need to combine like terms variables with variables numbers with numbers
1-2(these are the a's)
-1a(or just -a)
-a+32>0
now we need to isolate the variable to do this we need to do the reciprocal or opposite of each operation subtract 32 by 0
-a>-32
almost done our variable can not be negative so divide -1 into -32 and remember 2 negatives make a positive
a>32 BUT always when dividing by a negative our signs flip so the solution is a<32

Answer 13

Word Rt you better Than My Teacher Lol These fools Pist me off jst give me work and dont show me how to do it lol

Answer 14

lol my teachers are like that with virtual school learn a lot on here though
