Answer:
The correct one is A
Step-by-step explanation:
2x-y=10
y=1/2 × x+5
Now you substitute the value of y into the first equation.
2x - (1/2 × x+5) = 10
Solving this equation for x you get that x=6
Now substitute the value of x any of these two equations, doesn't matter. Let's say we do with the first one.
2×6-y=10
12-y=10
-y=10-12
-y= -2
y=2
And so you've got the first one which is, (x,y)=(6,2)

Answer:
84ft^2
Step-by-step explanation:
Given data
Base= 12feet
Height= 14feet
The expression for the area of a triangle is
Area= 1/2bh
Area= 1/2*12*14
Area= 6*14
Area= 84 ft^2
Hence the area of the triangular garden is 84ft^2
