We have that
5x+6y=10
4x+7y=19

using a graph tool
see the attached figure

Part A)
the solution is the point (-4,5)
x=-4
y=5

Part B)
we know that

If a system has at least one solution, it is said to be consistent .

If a consistent system has exactly one solution, it is independent

the equations are independent and consistent. Their graphs intersect at one point

You have to find a common denominator. 12 is the easiest to get in this case. 5/4 * 3= 15/12, 1/3 * 4=4/12. 15/12-72/12+4/12. The answer is 53/12

Answer:

22.2 ft²

Step-by-step explanation:

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{50}{360}$

= π × 7.13² × $\frac{5}{36}$

= $\frac{7.13^2(5)\pi }{36}$ ≈ 22.2 ft² ( nearest tenth )
