Answer:
4$
Step-by-step explanation:
The ratio between the $5.80 spent for 58 text messages is $0.10. This means that each text message sent is $0.10. So you just multiply $0.10 and 40 text messages to find that it costs $4 to send 40 messages.
(m^4 + m^3 + 4) + (-5m^4 + 4m + 1) =
m^4 + (-5m^4) + m^3 + 4m + 4 + 1 =
-4m^4 + m^3 + 4m + 5
The answer is B
Profit = paid - supplies
Plug in the given values. We are finding out how much money he needs per room, if he is doing 4 rooms, and subtracting the supplies: 300 = 4n - 4*32.50
Simplify: 300 = 4n - 130
Add 130 to each side. 430 = 4n
Divide by 4 on each side: 107.50= n
300 = 4(107.50) - 130? True
This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.
Answer:
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the distance in miles
y ----> the time in hours
we have
The distance is equal to subtract 35 miles from 230 miles
The time is equal to subtract 1:30 pm from 4:30 pm
substitute in the formula of speed
<em>Isolate 3 hours</em>
<em>Isolate 195 miles</em>
Answer:
y = (10x + 600)/x
Step-by-step explanation:
To find the average cost, we must divide the total cost by the number of people.
The number of meals served will equal the number of people, since everybody gets just 1 meal.
Each meal is 10 dollars, plus the 600 rental fee.
The total cost will be the meal prices plus the fee, all divided by the number of people/number of meals, or x.
