Ok 5 x 8 = 40 so we have to do 3 x 5 because whatever you do to the bottom you have to do it to the top so 3 x 5 = 15 and 2 x 8 = 16 then add 15 + 16 to get 31

I need help,I need to use substitution but I don't know how
lions [1.4K]

If y=x+6 and y=-2x-3, then you can replace y in either equation with the equivalent expression given by the other equation. In this case, you have

x+6=-2x-3

and you can solve for x.

x+2x+6-6=-2x+2x-3+6\implies3x=3\implies\dfrac{3x}3=\dfrac33\impliesx=1

Then y=1+6=7.

For the second system, you can write

5x-y=-5\implies 5x-5x-y=-5-5x\implies-y=-5-5x

\implies-(-y)=-(-5-5x)\implies y=5+5x

Then substitute this into the second equation and you get

3x-6(5+5x)=24\implies3x-30-30x=24\implies-27x-30+30=24+30

\implies-27x=54\implies x=2

so that

y=5+5(2)=15

Jackie rolled a number cube 20 times. She rolled an odd number 8 times. What is the experimental probability, and what is Theore
V125BC [204]
Based on the information given...

Experimental - how many times something occurs over how many times experiment is done

Odd number rolled - 8 times

Total times done - 20

This would mean the experimental probability is 8/20

Theoretical - favorable outcomes over possible outcomes

On a 6 sided number cube, you have 3 chances of rolling an odd, over 6 possible roll outcomes

This would mean the theoretical probability is 3/6 or 1/2
