Answer: step 4
Step-by-step explanation:
Answer:
1. x= -2 2. x= -5 3. x= -11/10
Step-by-step explanation:
1. 5x-3x -4+4=3x-3x+8+4 2x/2=-4/2 x=-2
2. -4x+7x +7-7=-7x+7x-8-7 3x/3=-15/3 x=-5
3. 6x+4x+7-7=-4x+4x-4-7 10x/10=-11/10 x=-11/10
One because it only has one number behind the decimal
You use rise over run. So you first count the rise( how many upwards is the point) then count the run( how many to the right or left is the point)
2x =50 since it is an isosceles triangle
x =25
the sum of all angles in a triangle is 180
5y + 10 + 50 + 2x=180
5y + 10 + 50 +50 =180 because 2x = 50
combine like terms
5y +110 = 180
subtract 110 from each side
5y = 70
y = 14
