Its A. 10^15 because, 10^18 x 10^-3 = 10^18-3 = 10^15
Answer:
c= 20h + 60
Step-by-step explanation:
The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.
Answer:
No, they are not mutually exclusive because a customer can purchase a burger and fries together.
Step-by-step explanation:
Mutually exclusive events are events that cannot occur at the same time, e.g. I cannot sleep while running. In the case of a restaurant, you could consider purchasing pizza and burgers as mutually exclusive since most people would only purchase one of them (unless they eat a lot). But burgers and fries are not mutually exclusive because people can purchase them together.
Answer:
B: -1/2(-2)(x+3)= -10(-1/2)
Step-by-step explanation:
The best step to begin to simplify the equation is to try to get a coefficient for the variable x equal to 1. we can do that if we multiply in both sides of the equation by -1/2 as option B.
So, if we keep simplifying, we get:
-2 (x + 3) = -10
-1/2(-2)(x+3) = -10(-1/2)
x + 3 = 5
x + 3 - 3 = 5 - 3
x = 2
