12x-3-3x=5-(x-8)
9x-3=5-(x-8)
9x-3=5-x+ 8
9x-3=13-x
9x=16- x
10x=16
X= 8/5
The answer would be 19/250.
7.6% = 7.6/100
0.076
0.076/1 * 1000/1000
76/1000
19/250.
Hi there!
The answer is D.
We need to isolate each square root. We can simply do this by adding
![\sqrt{4x + 8}](https://tex.z-dn.net/?f=%20%5Csqrt%7B4x%20%2B%208%7D%20)
to both sides of the equation.
When we isolated the square roots, our equation looks like this:
![\sqrt{7x - 7} = \sqrt{4x + 8}](https://tex.z-dn.net/?f=%20%5Csqrt%7B7x%20-%207%7D%20%3D%20%5Csqrt%7B4x%20%2B%208%7D%20)
Now we can easily square both sides of the equation, which would have been much harder earlier.
~ Hope this helps you!
Answer:
The Inequality representing the situation is
.
Family needs to drive at least <u>40 days</u> to reach a distance of at least 1, 4000 miles.
Step-by-step explanation:
Given:
Number of miles family drive per day =350 miles
We need to find the number of days d they must travel to reach a distance of at least 1, 4000 miles.
we need to write the inequality to representing the situation.
Solution:
Let the number of days to be driven be !['d'](https://tex.z-dn.net/?f=%27d%27)
So now we can say that;
Number of miles family drive per day multiplied by the number of days to be driven should be greater than or equal to 14000.
framing in equation form we get;
Hence The Inequality representing the situation is
.
On Solving we get;
Dividing both side by 350 we get;
![\frac{350d}{350}\geq \frac{14000}{350}\\\\d\geq 40\ days](https://tex.z-dn.net/?f=%5Cfrac%7B350d%7D%7B350%7D%5Cgeq%20%5Cfrac%7B14000%7D%7B350%7D%5C%5C%5C%5Cd%5Cgeq%2040%5C%20days)
Hence Family needs to drive at least <u>40 days</u> to reach a distance of at least 1, 4000 miles.
