Answer:
x = 600 mph
Step-by-step explanation:
It is given that,
Speed of the jet stream = 100 mph
It travels 1200 miles in the same amount of time as it takes to fly 1000 miles against the jet stream.
We need to find the airplane's average rate in calm air. Let it is equal to x mph.
As time in same in both cases. ATQ,
So, the airplane's average rate in calm air is 600 mph. Hence, this is the required solution.
A, 2. 35 times 55 represents the area, and that equals 1925. Subtract the 1250 from one bag from the 1925 you need to cover the area (do 1925-1250) to find how much more you need after using one bag. That gets you 675, so you'll need one more bag to cover that for 2 bags in total. The second bag will put you over the 675 you need, but that's ok because now you have enough to cover the 1925 sq foot area.
Given:
Cost of small candles = $4.00
Cost of large candles = $6.00
They have at most 50 candles, and want to make at least $100.
To find:
The system of linear inequalities represents the situation.
Solution:
Let x be the number of small candles and y be the number of large candles.
At most 50 candles means total candles must be less than or equal to 50.
Want to make at least $100. It means, the total sales must be greater than or equal to $100.
Therefore, the inequalities in the system of linear inequalities are and .
Answer:
x < 1/2
Step-by-step explanation:
Distribute: -9x - 18 > 9x - 27
Collect like terms: -18x > -9
Divide both sides by -18: x < 1/2.
The sign changes because both sides were divided by a negative number.
