Answer:
Step-by-step explanation:
1:5=1/5
1/5=20/100
20/100= 20%
20% of bag is pink marbles
first, distribute -6 to (2b + 1), giving you -12b - 6, and then on the another side of the equation, distribute -2 to (5 + 4b) giving you, -10 - 8b. now we need to put our coefficients on one side so we will add 8b to each side of the equation, giving us -6 = -10 - 8b + 12b, then we will add 10 to both sides of the equation giving us, 10 -6 = -8b +12b, this gives u 4 = 4b. then, you would solve for b, which equals 1.
To factor (q+3)(q+6)
q^2+6q+3q+18
q^2+9q+18
(q+9)(q+2)
