I think this is how you do it, each triangle is 3, and the square is .5625 so 3 x 4 is 12+ .5625 so 12.5625, i hope i helped
Answer:
Side PN=26
y=16
Step-by-step explanation:
I put a photo of my work. It’s easier to do that then to try and put it all in words
N+d=34
.05n+.10d=2.60
Solve by substitution
n=34-d
.05(34-d)+.10d=2.60
1.7-.05d+.10d=2.60
.05d=.90
d=18 dimes
18+n=34
n=16 nickles
Is this a true/false or do you need an actual mathematical answer?
i will edit my this to answer your question.
I'm just not exactly sure what you are asking :-/
