C. Vinegar bubbles when baking soda is added
Answer:
Jane used 2/5 of a scoop more of brown sugar than she did with white sugar.
Step-by-step explanation:
If you want to find how much more something is from something else, you subtract. So, subtract 9/10-1/2. If you want to subtract, they should both have the same denominator. So, 9/10-1/2 is the same as 9/10-5/10. 9/10-5/10 is equal to 4/10 which is simplified to 2/5.
Answer:
The correct option is;
y - P = two fifths (x - Q).
Step-by-step explanation:
The equation for the old route is given as follows;

Therefore, we have;
The slope of the equation of the old route = 2/5
Given that the new route is parallel to the old route and passes through the point (Q, P), the slope of the new route = 2/5 and the equation of the new route in slope and intercept form can be written as follows;
y - P = 2/5×(x - Q)
Therefore, the correct option is y - P = two fifths (x - Q).
Answer:
441
Step-by-step explanation:
x^2 + 42x + c
Take the coefficient of x
42
Divide by 2
42/2 = 21
Square it
21^2 =441
This is the value of c
