The first one is right and the third one is right, but you need to switch the 15% and the 95%.
In #2, it's asking for the kids that <em>are not</em> Michael, so it'd be 18/19. Which is then rounded to roughly 95%.
#4 asks for 6/40 = 15%
Answer:
I worked out the inequality and i got -2<x
Step-by-step explanation:
First substitute the second equation into the first one:
-3x - 3(-5x - 17) = 3
Next distribute the parenthesis:
-3x + 15x + 51 = 3
Then combine like terms:
12x + 51 = 3
Now subtract 51 from each side:
12x = 48
Lastly to get x, divide each side by 12:
x = 4
Now put this into the second equation:
y = -5(4) - 17
Multiply:
y = -20 - 17
And subtract:
y = -37
The solution is (4,-37). Hope this helps!
