Answer:
(2, 2)
Step-by-step explanation:
In this case, elimination would be the most efficient means of solving.
Simply, add the two equations, and you will be left with only one variable to solve for. (In this case y) You are then able to take your solution and plug it into an equation and solve for x, therefore giving you their intercept.\
5x + 10y = 30
+
-5x + 15y = 20
(x's cancel) 25y = 50
25y = 50
y = 2
5x + 10(2) = 30
5x + 20 = 30
5x = 10
x = 2
The solution to this equation is (2, 2)
Answer:
15
Step-by-step explanation:
3x3=9
so therefore you need to multiply 2 by 3=6
9+6=15
If i’m not mistaken, it should be 2/10, or 20/100. and it’s percentage would be 20%
Step-by-step explanation:
For triangle total degree=180°
2x+3x+4x=180
You get x=20°
Hence angles respective are..
40°,60°,80°
