Answer: 10
Explanation:
20 ÷ (4- (10-8))
First off, you work your way outward. You start the furthest in, then head your way out. (10 - 8) is the furthest in, and 10 - 8 = 2. So now your equation looks like this:
20 ÷ (4 - 2)
Next, you do the (4 - 2) which equals 2. So now, the equation is this:
20 ÷ 2
So you finish it up with 20 ÷ 2 which equals 10.
Hope I made sense! :D
Answer:
C
Step-by-step explanation:
the variables in this system of equations are b and p these represent distance walked.
4b + 5p = 2 represents the total amount of time the walk takes
b + p = 8 represents the total distance walked :)
The answer isn't A only because the word problem states that from her house to the beach, it should be represented as b. And p for the beach to the park.
Qt when you take the q and you take the t is makes the answer mate
Answer:
Step-by-step explanation:
This can be set up like an inequality. Chances are just as likely that you are in ratios and proportions, but since I'm not sure, I'm going with the easier way for this particular situation. The inequality, before reducing, is:
20 < 4x < 40,
which states that a 4 minute shower uses less than 40 gallons but greater than 20 gallons, where x is the number of gallons of water. Therefore,
5 < x < 10 results when you simplify. This puts things in terms of 1 minute now. This states that a 1 minute shower uses less than 10 gallons of water but more than 5 gallons. We got this by dividing everything by 4.
Now that things are in terms of a single minute, all you have to do is multiply the greatest number of gallons by 18 and the least number of gallons by 18 (and the x as well) to get the number of gallons used in an 18 minute shower as a range:
90 < 18x < 180
