28(y-1/7)= 28y-4
this deals with reducing fractions to their lowest terms.
Part 1:
6(x-5) = 5(x+5) (x = 55)
4y + 2 (-3 + 2y) = 1-y (x = 7/9)
Part 2:
4(a-6) = 8a - (4a-24) (No Solution)
4(2x-8) = 8(x-8) (No Solution)
2(3x-3) = -6x-6 (Identity (x = 0))
Answer:
1. x= -1/3
2. y= -4, x= 2
3. y=-2, x=1
Step-by-step explanation:
General formula for circles at the origin is x^2+y^2=R^2 where R is the radius.So R^2=4225. Solve for R.
It's thirteen because it is too large.
