Answer:
(6,-4)
Step-by-step explanation:
-3x-9y = 18 (equation 1)
4x+3y = 12 (equation 2)
multiply equation 2 by 3, and add it to equation 2
-3x-9y = 18
12x+9y = 36
-----------------
X's cancel out
9x = 54
Divide both sides by 9
x = 6
Plug in 6 for x in any of the original equations
(Plugging into Equation 2)
4(6)+3y = 12 Multiply 4(6)
24+3y = 12 Subtract 24 from both sides
3y = -12 Divide 3 on both sides
y = -4
Therefore the solution is (6,-4).
Answer:
$36.9135
Step-by-step explanation:
Markup = 17% of 31.55
= 17/100 × 31.55
= 5.3635
Retail price = whole sale price + markup
= 31.55 + 5.3635
= $36.9135
-- The whole discussion involves 4 rooms, never more and never less,
so we can call the 4 rooms "1 job" for simplicity.
-- Patrice, by himself, does the job in 10 hours. So he does 1/10 of
the job each hour.
-- Working together, Patrice and April do the job in 6 hours. So when
they work together, they do 1/6 of the job each hour.
-- April's part of the job is (1/6 - 1/10) = (5/30 - 3/30) = 2/30 = 1/15 job per hour.
-- Her unit rate alone is 1/15 job per hour, or <em>15 hours</em> per job.
