Answer:
x = 3
y = 0
Step-by-step explanation:
x + 2y = 3 ---------eqn 1
x - y = 3 --------eqn 2
Using eqn 2 to find the value of y
x - y = 3
Making y the subject of the formula
x - 3 = y
y = x - 3
Substitute the value of y into eqn 1
x + 2y = 3
x + 2(x - 3) = 3
Open the bracket
x + 2x - 6 = 3
3x - 6 = 3
3x = 3 +6
3x = 9
Divide both sides by 3, to get value of x
3x/3 = 9/3
x = 3
To get the value of y, use eqn 2
x - y = 3
3 - y = 3
3 - 3 = y
y = 0
Hint, to know maybe the values are correct, insert the values into the equation
Let's use eqn 2
x - y = 3
x = 3
y = 0
Insert into the equation
x - y = 3
3 - 0 = 3
Our values are correct
Answer:
Step-by-step explanation:
Alright. Looking at the graph, angle CGE is equal to angle FGD.
FGD = 90-73
FGD = 17
Therefore, as angle CGE is equal to angle FGD, angle CGE is equal to 17.
Answer: 17 degrees.
Answer:
75
Step-by-step explanation:
assuming that all are children(answer will be adult ticket at the end)
124×5.20=644.8
872.5-644.8=227.7
8.50-5.20=3.30
227.7÷3=75.9=75 tickets(no decimal cause tickets are sold as a whole)
Answer for 1 is 22 degrees
Answer:
x=2
Step-by-step explanation: because the highest exponent is 2 then the value of the polynomial would be 2
