Answer:
lets find the exact value of w
7w - 7 = 7
+7 +7
7w = 14
/7 /7
w = 2
Now let's replace w with 2
5(2) + 1 = 11
She has totally 10+5+3=18 marbles, so the probability is 10/18=5/9. The complement is (9-5)/9=4/9.
Hope this helped!
That would be 1/5 in simplest form you can divide both numbers by 12 and when you do you get 1/5. Hope this helps!
To triple this number, you can triple the whole number, triple the fraction, then add them together.
3*3=9
1/2*3=3/2 (or 1 1/2)
Add them together.
9+1 1/2= 10 1/2
