It would be c I think: the problem says 2 divided by five and all the others are 5 divided by two
So I'm guessing that the unknowns here would be the number of postcards and letters that the couple sends to each other. So let's represent a letter with L and a postcard with the letter P. To get the equation of henry and isobel, you just need to plot the variables and the numbers. So the equation of henry is L + P = 150 because he only sent one letter and one postcard that made a total of 150. Isobel's equation is 5P + L =390 because isobel sent five postcards hence 5P, and one letter to make a total cost of 390.
You have to remember that "percent" means "hundredths".
So '25%' means 0.25 .
50 percent means 0.50 .
77% means 0.77 .
etc.
To find 41% of a number, multiply the number by 0.41 .

Answer:
A=45 square inches
Step-by-step explanation:
First find the height using Trig
Tan(45)=x/6
x=6tan(45)
x=6
Then area of a parallellogram is base x height so
A=7.5 x 6
A=45 square inches
