Answer: (-1,2)
Steps:
Solve by elimination
Multiply the first equation by 2 to make the coefficients of x in both equations the same
2(x+2y=3)
2x+4y=6
Then line them up and subtract
2x+y=0
-2x+4y=6
= -3y=-6
Divide both sides by -3 to isolate y
y=2
Then substitute 2 for y into one of the equations to find x.
x+2(2)=3
x+4=3
x=-1
Answer:
negative 1 over 27
Step-by-step explanation:
81 * negative 1 over 27 = -3
Answer:
The answer is 14.
Step-by-step explanation:
4.50 + 2.00x ≤ 32.50
32.50 - 4.50 = 28
28 / 2.00 = 14
The total number of tickets he can buy is 14.
500
Reason:
50 tens is basically ten 50 times. 10 x 50 = 500
I do not know the answer I think it is 43because it had four side and I think you have to divide 12 by 4 equal 3
