The third one is the answer
4(x-3)-2+2x=5(3x-7)-9x
4x-12-r+2x=5(3x-7)-9
4x-12-r+2x=15x-35-9x
6x-12-r=15x-35-9x
6x-12-r=6x-35
add 12 to -35 which equals -23.
add 6x+6x it cancels out to 0.
-r=-23
to make r positive just add it -23
since 23 is already negative it would become a positive because a negative + negative= positive
answer: r=23
Answer:
Hey there!
There are a total of 20 children, and 2+6, or 8 are girls.
Thus the probability of choosing a girl is 8/20, or 2/5.
There are 2 left handed girls, so the probability is 2/20, or 1/10.
Hope this helps :)
