First, you have to write down the inequality:
-2*x>30
Then you must figure out how to solve this. The way I would solve this is to divide 30 by -2 and then use a number greater than that.
30/-2=-15
so you have to chose a number that is bigger than -15 in order to get the answer.
-2*-16=32
That makes the new inequality 32>30.
That is the answer to the inequality.
Answer:
Step-by-step explanation:
step 1
Find out the number of revolutions in one hour
we know that
The bicycle wheels are making 30 revolutions per minute
One hour are 60 minutes
so
using proportion
step 2
Find out how many feet the bicycle will travel in one hour
we know that
A bicycle moves approximately 7 feet with each revolution and the number of revolutions in one hour is 1,800
so
Multiply the number of revolutions in one hour (1,800 rev) by 7 feet
<span>In the question "Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression represents her gross pay each day"
To obtain the expression that represents her gross pay each day, we divide the given expression by 7 to get (35h + 56) / 7 = 35h / 7 + 56 / 7 = 5h + 8
Therefore, the expression that represents her gross pay each day is 5h + 8.</span>
Answer:
since, hcf(312, 37) = 1
therefore, the answer will come in decimal form.
i.e., 8.4324324324
