Answer:
Step-by-step explanation:
You didn't list the options from which we are to choose as your system of inequalities, but that doesn't matter...we'll come up with them on our own and then you can match them to your options. The first inequality is going to be about the number of hours worked. The second inequality is going to be about the money earned. Hours worked and money earned have to be in 2 different inequalities because they are not the same. If x is one job and y is the other, and the combination of these jobs cannot be more than 12 hours total, then the inequality for this is:
x + y ≤ 12
That represents the hours worked. As far as the money goes, she makes $8 per hour, x, at the first job, and $9 per hour, y, at the second job. She wants the combination of these wages to be at least $100. The inequality that represents the money earned is:
8x + 9y ≥ 100
That is the system that represents your situation.
3x - 5 = 1/2x + 2x 3x - 5 = .5x + 2x3x - 5 = 2.5x-3x = -3x -5= -.5x divide by -.5 on both sidesx = 10
IT IS 180 because 12*15 is one 180 and it cant go over 187.
Answer:
31136
Step-by-step explanation:
To find the how much an number increased by a percent. Divide the percent by 100. 23/100=0.23.
Then multiply 0.23 by the original number which is 25,314. Which gives us about 5822.
Then since it INCREASED, we are going to add that number it increased to the original. 25314+5822= 31136.
