To solve this, I'm assuming that the equations both represent angles:
There is a theorem that states that an exterior angle of a triangle is equivalent to the sum of two remote triangles. Knowing this:
11x + 7 = 7x + 14 + 25
11x + 7 = 7x + 39
4x = 32
x = 8
P = 6s
s = 3.4
P = 6(3.4) = 20.4 cm
Well she probably has 0 blue hair ties and 5 red hair ties.
Subtract 4 from both sides
R/10 = 5 - 4
Simplify 5 - 4 to 1
R/10 = 1
Multiply both sides by 10
R = 1 × 10
Simplify 1 × 10 to 10
<u>R = 10</u>
5 days because there are 24 hours in a day so every six hours you can take 4 a day
