I did that but it’s to much work to send it to you
Yes this is because when you multiply or divide by a negative the inequality symbol flips
Answer:
this question is very unorganized please make it more clear, thanks :)
Step-by-step explanation:
<span>2n + 5 + n + 3n = (2n + n + 3n) + 5 = 6n +5
</span>Expression I is equivalent to the expression II.
R=number of hours ruby worked
i=number of hours issac worked
s=number of hours shetland worked
ruby worked 8 more than issac
r=8+i
shetland worked 4 times as many as ruby
s=4r
total they worked 136
r+i+s=136
so
we gots
r=8+i
s=4r
for r=8+i
solve for i
minus 8 both sides
r-8=i
so
r+i+s=136
subsitute r-8 for i and 4r for s
r+r-8+4r=136
6r-8=136
add 8 to both sides
6r=144
divide both sides by 6
r=24
sub back
r-8=i
24-8=i
16=i
s=4r
s=4(24)
s=96
ruby worked 24 hours
issac worked 16 hours
shetland worked 96 hours
