Answer:
x=2
y=-1
Use the system of equations to solve for it
If it’s a half circle, the central angle should be 180 degrees.
Answer:
He owes $175
Step-by-step explanation:
He paid a 30% deposit of 75 dollars. Let the total cost be x
30% of x is 75 dollars. In equation form
.30x = 75
Divide each side by .30
.30x/.30 = 75/.30
x =250
The total cost is 250
Since he already paid 75
The amount he still has to pay is
250-75 = 175

Answer: True
Step-by-Step Explanation:
=> 2x + 3y = -7 (Eq. 1)
=> -x = 2y (Eq. 2)
=> x = 1, y = -3
Substitute values of ‘x’ and ‘y’ in Eq. 1 :-
=> 2x + 3y = -7
= 2(1) + 3(-3) = -7
= 2 + -9 = -7
=> -7 = -7
=> LHS = RHS
Therefore, it is a Solution.
