a>82 is 42 degrees warmer than 40.
The required amount Weiming has to pay is given by the limit of $150
more than the amount Joyce has to pay.
Response:
- The greatest amount Weiming has to pay is<u> $180</u>
<h3>Which method can be used to analyze the amount paid by Weiming and Joyce?</h3>
Amount Weiming agrees to pay ≥ 2 × Joyce agrees to pay
Amount Weiming agrees to pay ≤ 150 + Amount Joyce agrees to pay
Let <em>x</em> represent the amount Weiming agrees to pay, and let <em>y</em> represent
the amount Joyce agrees to pay, we have;
x + y = 210
x ≥ 2·y
x ≤ y + 150
When the amount Weiming is $150 more than Joyce, which is the
limiting amount for Weiming, we have;
x = y + 150
Which gives;
y + 150 + y = 210
2·y = 210 - 150 = 60
y = 60 ÷ 2 = 30
x = 30 + 150 = 180
Therefore;
- The greatest amount Weiming has to pay is, x = <u> $180</u>

Answer:
-8p + 7
n = --------------
8 - 5p
Step-by-step explanation:
Let's group the n terms in 5pn-8p=7n-7 .
Subtract 5pn from both sides. This results in -8p = 7n - 7 - 5pn
Now add 7 to both sides. This will group the n terms on the right side:
-8p + 7 = 7n - 5pn
Factor n out of 7n - 5pn:
-8p + 7 = n(7 - 5p)
Finally, divide both sides by (7 - 5n) to isolate n:
-8p + 7
n = --------------
8 - 5p
<span>First note that y cannot equal -7 or -1 as division by zero is undefined. So that if it comes up in our solution we know that it is not a real solution.
[(y+4)/(y+7)]+1=(y+3)/(y+1) make the left side have a common denominator
(y+4+y+7)/(y+7)=(y+3)/(y+1) combine like terms on left side
(2y+11)/(y+7)=(y+3)/(y+1) cross multiply
(2y+11)(y+1)=(y+3)(y+7) expand
2y^2+13y+11=y^2+10y+21 subtract y^2 from both sides
y^2+13y+11=10y+21 subtract 10y from both sides
y^2+3y+11=21 subtract 21 from both sides
y^2+3y-10=0 expand so factoring is easier
y^2-2y+5y-10=0 factor
y(y-2)+5(y-2)=0 which is equal to
(y+5)(y-2)=0
y=-5 or 2</span>
