To find your answer, set up a proportion. 189 over 630 is equal to x over 100. Multiply 189 by 100 to get 18,900, and then divide 18,900 by 630 to get 30. 30% is your final answer

Solve the following system. y = x 2 - 9x + 10 and x + y + 5 = 0. The solutions are
shepuryov [24]
X+y+5=0

y=-x-5

If a solution exists y=y so we can say

x^2-9x+10=-x-5  add x+5 to both sides

x^2-8x+15=0 now factor

x^2-3x-5x+15=0

x(x-3)-5(x-3)

(x-5)(x-3) so x=3 and 5, using y=-x-5

y(3)=-8 and y(5)=-10

So the two solutions are:

(3,-8) and (5,-10)
