Where to Dig: The dinosaur's neck bones are at another point on the grid — the solution to the system of equations below. Find the fossil! x + y = 5 –3x + 2y = 5

(1,4)

Step-by-step explanation:

Solve top equation for x:

x = 5 – y

Sub into bottom equation:

–3(5 – y) + 2y = 5

–15 + 3y + 2y = 5

5y = 20

y = 4

Backsolve in top equation:

x + 4 = 5

x = 1

(x, y) = (1, 4)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
