I'll do the left side.
1:
Inverses are your friends, for example to get 
where n is on one side, do the inverse of subtraction ( addition) so you get 
On "y" there is a <em>coefficient </em>of 5, aka 
, the inverse of multiplication is division
You finish the rest, but you gotta remember this, isolate the variable (x, y, z, whatever) by doing inverses
inverses
addition - subtraction
multiplication - division
<em>Everything in math builds on this!!!</em>

Answer:$419.30
Step-by-step explanation:
First divide 3 month cost by 3-$89.85/3= $29.95. Do the same for 8 months( $239.60/8= $29.95. Since $29.95 is common for both take that $29.95 x 14 months equaling $419.30.
Proportion women /men = 2/7 = x/490 7x= 2· 490 :7
X = 2·70 = 140
She washed 30 plates from 7:30 to 7:35.....so she washed 30 plates in 5 minutes.....30/5 = 6 plates per minute
so if she started washing plates at 7:15 and ended at 7:38...how many plates did she wash....
from 7:15 to 7:38 is 23 minutes...and if she can wash 6 plates per minute, then in 23 minutes, she can wash (23 * 6) = 138 plates <==
the equation...
y = -6x + b...with b being the number of plates she started with and x being the number of minutes and y being the plates she has left to wash...I am not 100% sure on this equation...I am so sorry
