Answer:
The answer is x = 20
Step-by-step explanation:
If you set both equations equal to each other and solve for x, you will get 20.
3x+32 = 5x-8 add 8 to both sides
3x+40 = 5x subtract 3x from both sides
40 = 2x divide by 2 on both sides
20 = x
60,40,35,45,39
Put in order from least to greatest
35, 39, 40, 45, 60
Range = Max - Min
Range = 60 - 35
Range = 25
Answer
D) 25
Answer:
864 cubic meters
Step-by-step explanation:
Rectangular prism = 5x9x12=540
Triangular prism = 1/2(9)(6)(12)=324
540+324=864 cubic meters
Answer:
Its the top right one
Step-by-step explanation:
The Min is 5, the Q1 is 7, the median is 9, the Q3 is 12, and the max is 15
Hope this helps
Let x be the number of mm of pure alcohol to be added:
I will add the mm to express the volume in mm
100mm.(19%) + (100%).x mL = (100 mL+x mL).(40%).
Now right again without the %
100.(0.19) + x.(1) = (100+x).(0.4)
19 + x = = 40 + 04x
x - 0.4x = 40 - 19
0.6 x = 21
x = 21/0.6 and x = 35 mL. This te quantity of pure alcohol should to be added to get a solution at 40%.
