Answer:
2a +b =5
Step-by-step explanation:
4a + 2b = 10
Divide each side by 2
4a/2 +2b/2 = 10/2
2a +b =5
Answer:
D
Step-by-step explanation:
Plug in the x values to get the y values
Answer:
x = 3
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
10x + 2 is an exterior angle of the triangle, thus
10x + 2 = 2x + 1 + 25
10x + 2 = 2x + 26 ( subtract 2x from both sides )
8x + 2 = 26 ( subtract 2 from both sides )
8x = 24 ( divide both sides by 8 )
x = 3
