Answer:
y = 50 x = 10.
Step-by-step explanation:
Let's solve for y first.
We know the line angle 80 and angle 2y-5 is on a 180 degree line.
Now we can do our work:
180 - 85 = 95
2y - 5 = 95
95 + 5 = 100
100 ÷ 2 = 50
2(50) - 5 = 95?
The equation is correct, therefore y = 50.
No we do the same thing for the other angles, 90 and 3x + 55.
Again, 180 line.
180 - 95 = 85
3x + 55 = 85
85 - 55 = 30
30 ÷ 3 = 10
3(10) + 55 = 85?
The equation is correct therefore x = 10.
Thus, y = 50 and x = 10.
Because there's times when u need to double for instance a cup so u have to add one morecup
Answer:
7%, 10%
Step-by-step explanation:
Man, I'm doing AP Stats homework right now and it's on conditionals too.
P(X given Y) = P(X and Y)/P(Y) = 0.03/0.45 = 1/15 for A|B
and thus 0.03/0.30 = 1/10 for B|A
So 7% and 10% are the answers.
3x^2 - 7x + 9 - (2x^2 + 4x - 8).....distribute the - thru the parenthesis
3x^2 - 7x + 9 - 2x^2 - 4x + 8....combine like terms
x^2 - 11x + 17 <== this is how much less it is
x^2 - 11x + 17.....when x = 2
2^2 - 11(2) + 17 =
4 - 22 + 17 =
21 - 22 =
-1 <====
