Area = (14 x 20) - ( 5 x 9)
Area = 280 - 45
Area = 235 square cm
Answer:
The equation given in the question matches the situation C.
Step-by-step explanation:
A. The amount that Cindy paid for books was 15% of p i.e. it is only 
B. The amount is given to a charity after saving 15% of p. That means if p is the amount of charity, then there were a savings of 15% of p.
Therefore, the total charity payment after savings = p - 15% of p = 
C. The amount that Sandy paid for a shirt with 15% tax on p.
Therefore, if the price of a shirt is p, then total payment of Sandy after tax is = p + 15% of p = 
Hence, the equation given in the question matches the situation C. (Answer)

Answer:
3/5
Step-by-step explanation:
To have the best chance of pulling a pair with the same color you should try to get a pair of black socks. There is a 3/5 chance of pulling a black sock so this means for every 5 socks you pull you get 3 black socks or 2 navy socks. Either way you will get a pair of socks with the same color. (Double check to make sure I'm correct)
A farm had 480 acres more wheat than corn. Let use "W" to represent the Wheat and let use "C" to represent the corn. Hence, we have below:
W=C+480
The farmers collected 80% of the wheat and 25% of the corn and the area of the wheat is 300 acres less than the area of the corn:
W-0.8W=C-0.25C+300
0.2W=0.75C+300
We have two equations, two unknowns:
0.2(C+480)=0.75C+300
0.2C+96=0.75C+300
0.55C=294
C=534.55
