Answer:
(10, -5)
Step-by-step explanation:
Given system of equations is,
0.6x - 0.3y = 7.5
Divide this equation by 0.3
2x - y = 25 -------(1)
0.4x + 0.2y = 3
2x + y = 15 -------(2)
Now we subtract equation (2) from equation (1),
(2x - y) - (2x + y) = 25 - 15
-2y = 10
y = -5
From equation (1),
2x - (-5) = 25
2x + 5 = 25
2x = 20
x = 10
Therefore, (10, -5) will be the solution of the system of equations.
you have to add 90 +90 3 times then theres your answer :)
Answer:
Step-by-step explanation:
-1_| 2 6 7 -6
<u> -2 -4 -3</u>
2 4 3 -9
2y^2 + 4y + 3 - 9/(y + 1)
0.00072 in scientific notation is 7.2x10^-4
