2x + 3y = -21
2x = -21 - 3y
x = -10.5 - 3/2y
-10x + 2y = 20
-10(-10.5 - 3/2y) + 2y = 20
105 + 15y + 2y = 20
105 + 17y = 20
17y = -85
y = -5
2x + 3y = -21
2x + 3(-5) = -21
2x - 15 = -21
2x = -6
x = -3
Therefore, the coordinates are (-3, -5).
Answer:
75.50
Step-by-step explanation:
Let the original price P
As per given information, Price of a Discount ticket is 12.50 less than original price
Discount price of a ticket= P- 12.50
Also discounted Price= 63
According To Question
P- 12.50 = 63
P= 63+ 12.50
P= 75.50
Hence, the original price of a ticket is 75.70
Hence, the correct answer is 75.50
Answer:
v = 120
Step-by-step explanation:
The right angle is egual to 180-39-v, so it is: v-141
U now that the sum of the internal angles of a triangle is 180°.
180 = (v-48)+(v)+(v-141)
180 = 3v - 180
3v = 360
v = 360/3
v = 120
Answer:
60
Step-by-step explanation:
Because 30 is half of 60
