A varies directly with b → a = kb where k is the constant of variation (i.e. slope)
-2 = k × 3 ← substitute values into the formula above
-2/3 = k ← result of dividing both sides by 3
Answer: k =
Hmmm unless you can do negatives, I'd say 10 and 0. 10 minus 0 is 10 (which fits) and the product of 10 and zero IS zero. does that make sense?
Answer:
B
Step-by-step explanation:
6 times 50 = 300

Answer:
true
Step-by-step explanation:
if we say x is less than 7 and x is equal to 6 it makes sense that 6 is less than 7
Answer:
Step-by-step explanation:
<u>Use this formula for interest:</u>
- I = Ptr, where I - interest, P- principal, t- time, r - interest rate
<u>Substitute values and solve for r:</u>
- 18 = 150*6*r
- r = 18/900
- r = 2/100
- r = 2 %
