22 (what number is in the middle one you put it in ascending order)
18 (the first quartile is the first quarter of the sorted list)
23 (the third quarter, the number in between the last number and the median)
5 (the range between quartile 1 and quartile 3)
Have a great day <3
15+24= put it in the calculator u will find the answer(hope this helped)
A, B, and C. all of them are reasonable choices and wouldn’t give any conclusion, because not everyone has the flu
10x = 4(2x -9)
10x = 8x - 36
10x - 8x = -36 - 8x
2x = -36
2x ÷ 2 = -36 ÷ 2
x = -18
If you need a better explanation just as in the comments.
Happy to help! Please mark as BRAINLIEST! Thanks
The main idea here is to "translate" the words into maths.
First we need to identify the unknowns and label these.
We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters
Now lets write equations from the written problem.
We know that there are 36 coind total, thus:
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents.
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus:
10x+25y=585
We have two equations and two unknowns now, that needs to be solved to get the answer.
x + y = 36
10x+25y=585
