Answer:
x = 6
Step-by-step explanation:
We know that the angles in a triangle add to 180°, so we can add the angles shown in this triangle together, make them equal to 180° and solve for x.
90° + (4x + 3)° + 63° = 180°
90° + 4x° + 3° + 63° = 180°
4x° + 156° = 180°
4x° = 24°
x = 6
So, x = 6. Hopefully, this helped! If you have any further questions, let me know.
Answer:
NO solution
Step-by-step explanation:
5(3x+9)−2x=15x−2(x−5)
Step 1: Simplify both sides of the equation.
5(3x+9)−2x=15x−2(x−5)
(5)(3x)+(5)(9)+−2x=15x+(−2)(x)+(−2)(−5)(Distribute)
15x+45+−2x=15x+−2x+10
(15x+−2x)+(45)=(15x+−2x)+(10)(Combine Like Terms)
13x+45=13x+10
13x+45=13x+10
Step 2: Subtract 13x from both sides.
13x+45−13x=13x+10−13x
45=10
Step 3: Subtract 45 from both sides.
45−45=10−45
0=−35
It is the last one have a great day!
