The answer to this is 39 and 27
I think the answer is 8. not sure if its right though
Jose has $2.50 cents in total,
We need an equation to solve this. We will let d=dime.
dime=.10
nickel=.05
.10d + .05 (d + 11)=2.50
.10d + .05d + 0.55= 2.50
.15d + 0.55 = 2.50
.15d= 1.95
d= 13
There is 13 dimes. To get the nickels, you just add the 11 to 13 and you get 24 nickels.
When rotating 180 degrees counterclockwise the sign of the numbers change. A positive becomes a negative and a negative becomes a positive.
(5.1) becomes (-5,-1)
answer: (-5,-1)
6 +2.5 = 8.5
the horizontal line is 2.5 +2.5 = 5m
(use Pythagorean theorem)
area = 8.5 * 5 = 42.5 / 2 = 21.25 m^2
answer is the 3rd choice
