Answer:
= 18 red marbles
Step-by-step explanation:
Let x be the number of red marbles that must be added
Therefore;
New number or red marbles = x+12
Total marbles will be x+32
Thus;
The probability of selecting a red marble = (x+12)/(x+32)
Therefore;
(x+12)/(x+32)=3/5
5(x+12)=3(x+32)
5x+60+3x+96
2x=36
x=18
Answer:
P(even,blue) = 3/6 x 1/9 which is 1/18
Step-by-step explanation:
Hello,
<span>
Let's
x pairs of women’s shoes sold
</span>y<span> pairs of men’s shoes sold
R(x,y)=45*x+50y=2500 (each week)
Or the week, =0 =>50*y=2500=>y=500.

X^2 + 6x + 3 = 0
a=1, b=6, c=3
x1=[-6+sqrt (6^2-4*1*3)] / (2*1)
=[-6+sqrt (24)] / (2)
=-0.55
x2==[-6-sqrt (6^2-4*1*3)] / (2*1)
=[-6-sqrt (24)] / (2)
=-5.45
answer A
For this case we have the following expression:

Rewriting the expression we have:

In the division, if we have the same base, the exponents are subtracted.
Therefore, by rewriting the expression we have:
Answer:
The equivalent expression is given by:
