When it says "is a less than b" , it means b - a not a-b.

x+y +z = 105
z = 10y - 11
2x = 3y + 7

Substitute expressions in terms of "y" for x and z in top equation.
$\frac{3y+7}{2} + y + (10y-11) = 105 \\ \\ (3y+7) + 2y+2(10y-11) = 210 \\ \\ 25y-15 = 210 \\ \\ y = \frac{225}{25} = 9$

Substitute value of y to find x and z:
$z = 10y -11 = 10(9) - 11 \\ \\ z = 79 \\ \\ 2x = 3y+7 = 3(9) +7 \\ \\ 2x = 34 \\ \\ x = 17$

Answer:

18.8 miles.

Step-by-step explanation:

(b)(h)/2 = A.

In this circumstance, you are solving for h.

Isolate h.

h = 2 x A/b

Now, substitute 102.46 for A and 10.9 for b.

h = 2 x 102.46/10.9 = 2 x 9.4 = 18.8.

h = 18.8mi.
