Question

please help!!! with these problems:
a. x-7>10
b. 3x ≤ 21
c. 6n – 3 > –18
d. 3s + 6 ≤ –5(s + 2)
dont understand!!!!

Answer 1

what are you supposed to do? Solve for x or what?

Answer 2

find wat the varible is

Answer 3

x-7>10
add 7
x>17..........that's for a


b. 3x ≤ 21
divide by 3
x≤7.....for b


you do this for the rest.

Answer 4

hmm.. think that makes bit more sense thanks

Answer 5

c. 6n – 3 > –18
you add 3, then divide by 6
so 6n>15
n>15/6.....answer for c

d. 3s + 6 ≤ –5(s + 2)
start by distributing the left side.

3s+6≤-5s-10
add 5s to both sides
8s+6≤-10

subtract 6
8s≤-16
s≤-2

Answer 6

ok thanks... i understand that ...
