How do you solve 7+3m=-29,-5x+7=27,31=4-9y,-52-3u=8,and 6-x=15. I know I'm asking for a lot.

Isolate the variable by putting numbers over the equal sign and multiplying/dividing. I'll do them for you
A. 7+3m=-29
3m=-29-7
3m=-36
M=-12
B. -5x+7=26
-5x=26-7
-5x=19
X=-3.8
C. 31=4-9y
31-4=-9y
27=-9y
-3=y
D. -52-3u=8
-3u=8+52
-3u=60
U=-20
E. 6-x=15
-x=15-6
-1x=9
X=-9
Hope this helps

Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$
