Answer:
c. step three
Step-by-step explanation:
CORRECT WAY
step one: -7/ -2 / 4/9 (flip 4/9)
step two: -7/-2 * 9/4 (simplify)
step three: = 63/8
Step three is incorrect because it's not - it's positive.
She forgot that a negative divided by a negative is a positive.
So -7/-2 is the same as 7/2
Hope this helps ya!!!
Using the law of cosin
cos(angle) = adjacent leg / hypotenuse
We fill in what we know and solve for x:
cos(30) = x / 10
x = cos(30) * 10
x = 5 SQRT(3)
The equation is: (y+3)/(-1+3) = (x-5)/(3-5);
Then, (y+3)/2 = (x-5)/(-2);
Finally, y+3 = -x+5;
y = -x + 2;
8 ounces of distilled water may be added
I believe it’s the second option sorry if I’m incorrect
