Answer:
Step-by-step explanation:
Let the number be x
1.x-10
3.-8x+1
4.19x-½
5.(x+15)²
I think its 3,600, because you usually have to multiply the numbers.
Answer:
x = 25
Step-by-step explanation:
The two angles form a straight line which is 180 degrees
2x+10 + 4x+20 = 180
Combine like terms
6x+30 = 180
Subtract 30 from each side
6x+30-30 = 180-30
6x = 150
Divide by 6
6x/6 = 150/6
x=25
