Answer:
x= 2
Step-by-step explanation:
5*2= 10 then add the x at the end
5*4=20
then you divide both sides by 10
(10x/10)- (20/10)
x= 2
or if your rewriting it then:
(5*2x)- (5*4)=?
Hope this helped :D
Answer:
2/15
Step-by-step explanation:
There is a 4/10 probability that she chooses blue the first time, but the second time it is a 3/9 chance because she didn't put the marble back so there are 9 marbles in total, 3 blue ones.
4/10 x 3/9 = 2/5 x 1/3 = 2/15
I hope this helps :)
Edit: Messed up the multiplication, whoops!
X - 3pt baskets (he reaches 3x points)
y - 2pt baskets (he reaches 2y points)
We know, that y=x+43
97 - 1 free throw = 97 - 1 = 96
Sum of points: 96
3x + 2y = 96. Substitute to "y" an expression "x+43" :
3x + 2(x+43)=96
3x+2x+86=96
5x=10 |:5
x=2
So y=x+43=2+43=45
He has made 2 three points baskets and 45 two points baskets
Price increase is $ 22-20 =$2 so the percent increase is 2/20 x 100= 10%
