Answer:
4<em>s</em> + 10<em>p</em> <= 100
<em>p</em> >= 5
Step-by-step explanation:
So it's important to remember here that this isn't one linear inequality to represent everything, it's a system. One of the inequalities that are part of the answer won't answer the entire question by itself, so don't worry about that. It might sound like tedious work, but you can break it down pretty easily into logic.
So the soil costs Marsha $4 per bag, and the plants cost her $10 each. She can't spend more than $100 dollars.
Let <em>p</em> = number of plants and let <em>s</em> = number of bags of soil
If each soil bag costs her $4, then 4<em>s</em> is the amount she spends on soil (4 [which is the cost of each individual soil bag] x number of bags = total cost of soil bags).
If each plant costs her $10, then 10<em>p</em> is the amount she spends on plants (same logic).
Because she can't spend more than $100 on both soil and plants together,
4<em>s</em> + 10<em>p</em> has to be less than or equal to 100.
4<em>s</em> + 10<em>p</em> <= 100
Since she wants to buy at least 5 plants, <em>p</em> has to be greater than or equal to 5.
<em>p</em> >= 5
And there you have it! Your system of inequalities is:
4<em>s</em> + 10<em>p</em> <= 100
<em>p</em> >= 5
Pretty simple c:
Answer:
0.025 meters large
First box = 0.025
Second box = meters or m
Step-by-step explanation:
Just drag the decimal twice to the left since the 10 has a power of -2.
The last one cuz when one exponent is in the parentheses and one isnt, u multiply
Answer:
222x + 888 = 303030
Step-by-step explanation:
If he raises the amount of push-ups he does by 222, then we can put the x with it, which represents the number of days. Since we are adding onto the 888 a day we can put that without the variable. If you were to solve this equation you would get the amount of days it would take to reach 303030 push-ups a day.
Hope this helps!
Answer:
18 minutes
Step-by-step explanation:
7.2 litres is 7200ml
each minute 400ml leaves the tank
so the question being asked is how many 400's are there in 7200...
7200 divided by 400 is 18.
