30/7
Step-by-step explanation:
1.5kg : 350g
1kg = 1000g
So, 1.5kg = 1500g
1500g : 350g
1500/350 = 30/7
The answer is 30/7.

So how you go about this problem is to first write an equation for how much each company will cost.
For Company A, it costs $120 plus some more.
The some more part can just be written as .4x where x is the number of miles
(2 miles = .4+.4 = .4(2) =.8)
So for if the cost for Company A is "A"
![A=120+.4x](https://tex.z-dn.net/?f=A%3D120%2B.4x)
Do the same thing for Company B but with the different numbers
<span>
![B=70+.5x](https://tex.z-dn.net/?f=B%3D70%2B.5x)
</span>
Find the number of miles in a day at which the rental costs for Company A and Company B are <span>the same</span>
"The same" here means equal so set the two equations equal to each other (that means the cost of Company A=the cost of Company B or A=B)
![A=B](https://tex.z-dn.net/?f=A%3DB)
![120+.4x=70+.5x](https://tex.z-dn.net/?f=120%2B.4x%3D70%2B.5x)
Now use algebra to solve for x
<span>
![120+.4x=70+.5x](https://tex.z-dn.net/?f=120%2B.4x%3D70%2B.5x)
</span><span>
![50+.4x=.5x](https://tex.z-dn.net/?f=50%2B.4x%3D.5x)
</span><span>
![50=.1x](https://tex.z-dn.net/?f=50%3D.1x)
</span>
![\frac{50}{.1} = \frac{.1x}{.1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B50%7D%7B.1%7D%20%3D%20%5Cfrac%7B.1x%7D%7B.1%7D%20)
<span>
![500=x](https://tex.z-dn.net/?f=500%3Dx)
</span>
The answer is 500 miles.
Answer:
Step-by-step explanation:
<u>The numbers from 1 to 9999 can be shown in the form of:</u>
Each of x, y, z represent the digits from 0 to 9, so 10 ways each.
<u>For each of the forms we have:</u>
<u>Total of:</u>
By the way this is applicable to any digit.
Answer:
I know this isn't the answer you'd like, but there's a graphing app called ''desmos'' and you can enter the equation in there and it gives you your answer.
Step-by-step explanation:
Translating this word problem into an algebraic equation, we get:
3x - 2/5 = 8/5.
Let's combine the constants: adding 2/5 to both sides of this equation yields
3x = 10/5, or 3x = 2.
Solving for x: x = 2/3
