Answer:
Determine the number of tables by dividing 754 by 6. If there is a remainder, the answer will need to be rounded tenths or hundredths . There is a remainder, so 125.6 tables are needed.
Step-by-step explanation:
Answer:
Step-by-step explanation:
If the variation is proportional dividing the y-value by the x-value will give the same result for all table entries. That quotient is the constant of variation (k).
Here 6.4/4 = 11.2/7 = 16/10 = 20.8/13 = 1.6
The value of y varies directly as x, and the constant of variation is 1.6. The equation is ...
y = 1.6x
1 2/5 = 7/5
3 4/5 = 19/5
7/5 * 19/5 = 133/25 = 5.32
Answer:
n ≥ 5
Step-by-step explanation:
The money that Janie earns (E) must be greater than or equal to the cost (c) of the CD.
In symbols,
E ≥ c
2n + 3 ≥ 13 Subtract 2 from each side
2n ≥ 10 Divide each side by 2
n ≥ 5
Janie must do five or more chores to buy the CD.
