Step-by-step explanation:
x + y = 9. => 2x + 2y = 18.
2x + 2y = 18
- (2x - 3y = -12)
=> 5y = 30, y = 6.
Therefore x + (6) = 9, x = 3.
The solution is x = 3 and y = 6.
Answer:
5/7 is the answers for the question
Answer:
x-17.5
Step-by-step explanation:
angles in a triangle add to 180
3x+8+(2x-3)+5x = 180
simplify(collect like terms):
10x + 5 = 180
solve:
10x = 175
x=17.5
Answer:
x 100
Step-by-step explanation:
because of the yvz angle its equals 100-12
There are many pairs that are solutions to this inequality. You can find them all by graphic this on a coordinate plane and then shading the region.
You can also plug any of the ordered pairs that they give you into the equation and see if they produce a true statement.
