Write an absolute value equation:
Center: 34
Distance: 4
Equation: |x-34|=4
Answer: x = 9, y = 5
Step-by-step explanation:
If all of the sides are equal, it is an equilateral triangle. Equilateral triangles are also equiangular. The angles of a triangle add up to 180 degrees, so each angle must equal 60 degrees.
set the equation equal to 60 to solve for x
7x - 3 = 60
add three to both sides
7x = 63
divide both sides by 7
x = 9
find y by setting the equation equal to 60
11y + 5 = 60
subtract 5 from each side
11y = 55
divide both sides by 11
y = 5
Since "chair" probably means "share", John will have 2 2/3 slices of pizza left.
The 12 slice pizza is split between 3 people, so each person gets 4 slices. John only eats 2/3 of his 4 slices, and 2/3 of 4 is 2 2/3.
