Multiple 6 with 3 and 1 with 2
2/18 = 19
Answer:
y = -6, x =2
Step-by-step explanation:
To solve by elimination, you have to line both equations up together. Then, you multiply both equations until one variable is removed.
2x+y = -2
5x + 3y = - 8
There are many different ways to solve an elimination problem, but generally you should look for the simplest route. Here, I would multiply the top equation by -3.
-6x -3y = 6
5x +3y = -8
Imagine you are adding the two equations together. You end up with
-x = -2
Then solve for x. In this situation, it is fairly simple. Take out a factor of -1.
x = 2
Finally, choose one of your beginning equations and plug your new-found x value back into the equation.
2(2) +y = -2
4 + y = -2
y = -6
- 47 → d
using the ' product rule '
(uv) = uv' + vu' = (3 × - 4) + (7 × - 5 ) = - 12 - 35 = - 47
The answer is c
the 1st high school has 4 vans so 4v and 2 busses so 2b and as a total they have 112 students so then you get the equation 4v+2b=112
the next high school has 6 vans so 6v and 3 busses so 3b with a total of 168 students so then you get the equation 6v+3b=168
Answer:
A. 60 Percent
