Answer: My thoughts on the loss of trees is quite disappointing due to the fact that we need them to survive. The loss of trees is not something good for the environment because many animals need it for shelters. It could cause animals to be endangered because they can’t hide from predators or hunters. Hopefully the trees will start increasing in 2020.
Answer:
Step-by-step explanation:
Let x be gallons of 7%
Let y be gallons of 3%
364 = x + y
y = 364 - x
364(0.06) = x(0.07) + y(0.03)
364(6) = x(7) + y(3)
364(6) = 7x + 3y
364(6) = 7x + 3(364 - x)
364(6 - 3) = 7x - 3x
364(3) = 4x
x = 273
y = 364 - 273 = 91
273 gallons of 7%
91 gallons of 3%
I believe it is A and D. All you have to do is add them all together and if both sides are the same then its a correct answer.
![73=(\frac{9}{10}x)+19](https://tex.z-dn.net/?f=73%3D%28%5Cfrac%7B9%7D%7B10%7Dx%29%2B19)
To solve x:
1. Substract 19 in both sides of the equation:
![\begin{gathered} 73-19=(\frac{9}{10}x)+19-19 \\ \\ 54=\frac{9}{10}x \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2073-19%3D%28%5Cfrac%7B9%7D%7B10%7Dx%29%2B19-19%20%5C%5C%20%20%5C%5C%2054%3D%5Cfrac%7B9%7D%7B10%7Dx%20%5Cend%7Bgathered%7D)
2. Multiply both sides of the ewuation by 10/9:
![\begin{gathered} 54\cdot\frac{10}{9}=\frac{9}{10}x\cdot\frac{10}{9} \\ \\ \frac{540}{9}=x \\ \\ 60=x \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2054%5Ccdot%5Cfrac%7B10%7D%7B9%7D%3D%5Cfrac%7B9%7D%7B10%7Dx%5Ccdot%5Cfrac%7B10%7D%7B9%7D%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B540%7D%7B9%7D%3Dx%20%5C%5C%20%20%5C%5C%2060%3Dx%20%5Cend%7Bgathered%7D)
<h2>Then, the value of x is 60 (x=60)</h2>
