Answer:
m2=125°
m3=65°
m4=125°
m5=65°
m6=125°
m7=65°
m8=125°
i know the reason in French if you want
Step-by-step explanation:
m2=180-65=125°
m2 = m4 =125°
m3 =m1 =65°
m3= m5 =65°
m4 =m6=125°
m7=m5 =65°
m8=m6=125°
Answer:
x = -4
Step-by-step explanation:
Simplifying
2[x + 4] = 2[-8 + -1x] + -2x
Reorder the terms:
2[4 + x] = 2[-8 + -1x] + -2x
[4 * 2 + x * 2] = 2[-8 + -1x] + -2x
[8 + 2x] = 2[-8 + -1x] + -2x
8 + 2x = [-8 * 2 + -1x * 2] + -2x
8 + 2x = [-16 + -2x] + -2x
Combine like terms: -2x + -2x = -4x
8 + 2x = -16 + -4x
Solving
8 + 2x = -16 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
8 + 2x + 4x = -16 + -4x + 4x
Combine like terms: 2x + 4x = 6x
8 + 6x = -16 + -4x + 4x
Combine like terms: -4x + 4x = 0
8 + 6x = -16 + 0
8 + 6x = -16
Add '-8' to each side of the equation.
8 + -8 + 6x = -16 + -8
Combine like terms: 8 + -8 = 0
0 + 6x = -16 + -8
6x = -16 + -8
Combine like terms: -16 + -8 = -24
6x = -24
Divide each side by '6'.
x = -4
Simplifying
x = -4
10 minutes because you multiply 2.5 four timss
Answer:
1 to 100,000
Step-by-step explanation:
Centimeters and kilometers are scales of the official unit of length in the SI, the meters.
In a meter there are 100 centimeters, and in a kilometer there are 1000 meters, so in a kilometer there are 1000(100)cm ⇒ 100,000cm
So the scale of 1 centimeter to 1 kilometer is:
1 to 100,000
