Answer:
15;9;-8
Step-by-step explanation:
1. 5/3x-3=2/3x+12
x=15 once you combine like terms
2. 5x+35-3x+12=7x+2
2x+47=7x+2
5x=45
x=9
3. 12x+20-3=9x-7
12x+17=9x-7
3x=-24
x=-8
This question is asking which two numeric values are closer to each other. The smallest gap in between Mercury, and Helium, which is the answer
First, we get the area of each tile: (100 cm = 1m)
.20 m* .15 m = 0.03m^2
Then, we solve for the total area of the wall:
5m*3m= 15m^2
Then we divide
15/0.03 = 500 tiles
Answer:
c, d and f are rational numbers
Step-by-step explanation:
![c) 3\sqrt{5}*2\sqrt{5}=3*2*\sqrt{5*5} = 3*2*5 = 30\\\\\\d) \dfrac{3\sqrt{5}}{2\sqrt{5}}= \dfrac{3}{2}\\\\\\f) \dfrac{2\sqrt{5}}{3\sqrt{5}}= \dfrac{2}{5}](https://tex.z-dn.net/?f=c%29%203%5Csqrt%7B5%7D%2A2%5Csqrt%7B5%7D%3D3%2A2%2A%5Csqrt%7B5%2A5%7D%20%3D%203%2A2%2A5%20%3D%2030%5C%5C%5C%5C%5C%5Cd%29%20%20%5Cdfrac%7B3%5Csqrt%7B5%7D%7D%7B2%5Csqrt%7B5%7D%7D%3D%20%5Cdfrac%7B3%7D%7B2%7D%5C%5C%5C%5C%5C%5Cf%29%20%20%5Cdfrac%7B2%5Csqrt%7B5%7D%7D%7B3%5Csqrt%7B5%7D%7D%3D%20%5Cdfrac%7B2%7D%7B5%7D)
