Answer:
base x height / 2
I'm guessing 10 and 17 are the base and height
10 x 17 = 170
170 / 2 = 85
85 is the area
Hope this helps

<span>The answer is six. Each line can intersect with each other line. If we call the lines A, B, C and D, imagine the intersections. Line A can intersect B, C and D - that's three. B can intersect A, C and D, but we have already counted where A and B intersect, so we just get another two. Then C can intersect A, B and D, but we have counted A-C and B-C already so we just get one more, where C and D intersect. So the answer is 3+2+1=6.</span>
N + d + q = 35
0.05n + 0.10d + 0.25q = 6
n = d + 5
n + d + q = 35
0.05n + 0.10d + 0.25q = 6.....multiply by -4
----------------
n + d + q = 35
-0.20n - 0.40d - q = - 24 (result of multiplying by -4)
----------------add
0.80n + 0.60d = 11
0.80(d + 5) + 0.60d = 11
0.80d + 4 + 0.60d = 11
1.40d = 11 - 4
1.40d = 7
d = 7 / 1.40
d = 5 <==== there are 5 dimes
n = d + 5
n = 5 + 5
n = 10 <==== there are 10 nickels
n + d + q = 35
10 + 5 + q = 35
15 + q = 35
q = 35 - 15
q = 20 <=== there are 20 quarters
