Answer:
x/2x+3 + 2x +3/x = 184 /65
x(2x + 3)–1 + (2x+3)x-1 = 184/65
(2x + 3)x / (2x +3)x = 184/65
2x² + 3x / 2x² + 3x = 184/65
1x= 184/64
x = 184/64
Answer:
![x=\frac{1}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
A quick review on PEMDAS, the order of how to solve an equation:
P - parentheses. When parentheses are being used, you have to do everything inside them before doing everything outside of them.
E - exponents. We'll skip these, since there aren't any exponents we need to worry about in this equation.
M/D - multiplication/division. I include these both together because they can be done at the same time.
A/S = addition/subtraction. Can also be done at the same time.
Some other things to note:
You add all the things with an x attached to it, and you add all the things without an x attached to it, and these never cross.
When you bring something from one side of an equal sign to another, you make it negative.
Let's solve for x using what we've learned:
![2(1-8x)=\frac{1}{2} (8-64x)\\2-16x=4-32x\\16x=2\\x=\frac{2}{16} \\x=\frac{1}{8}](https://tex.z-dn.net/?f=2%281-8x%29%3D%5Cfrac%7B1%7D%7B2%7D%20%288-64x%29%5C%5C2-16x%3D4-32x%5C%5C16x%3D2%5C%5Cx%3D%5Cfrac%7B2%7D%7B16%7D%20%5C%5Cx%3D%5Cfrac%7B1%7D%7B8%7D)
Answer:
He weighs 240 pounds
Step-by-step explanation:
What is her bill?
To do this on your own, you round up the amount by 5¢ or 10¢, whichever is closer, and then take 20% of her bill
Remember to put 20% into the calculator as 0.2 and multiply 0.2 by her bill that has been rounded up
Answer:
Step-by-step explanation:
(distance) d = (speed) s * t (time)
= 55km/h * 12.30m/s
= 11.275 km
= 11.275 * 1000
= 11275m
