Answer:

The choice B.

x =  -  \frac{20}{9}

Step-by-step explanation:

4(4x + 1) = 3x - 4(6 - x) + 8 \\ 16x + 4 = 3x - 24 + 4x + 8 \\ 16x - 3x - 4x =  - 24 + 8 - 4 \\ 9x =  - 20 \\  \\ x =  -  \frac{20}{9}

I hope I helped you^_^

Sloan [31]
6 mins goes into 60 mins ten times.

5000 \times 10 = 50000
now 50000 crauons are being made in 1 hour but your are trying to find how many crayons are being made in 3 hours
so, you multiply
50000 \times 3 = 150000
150000 is how many crayons are made in 3 hours.

A certain forest covers an area of 4000 km2. Suppose that each year this area decreases by 7%. What will the area be after 5 yea
Levart [38]
Answer:

2,600

Explanation:

Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.

Point B has coordinates ​(2​,1​). The​ x-coordinate of point A is -10 . The distance between point A and point B is 13 units. Wh
Paraphin [41]

hmmm we know B (2 , 1), and let's say the y-coordinate is "y" for A, so A (-10 , y).

~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{1})\qquad A(\stackrel{x_2}{-10}~,~\stackrel{y_2}{y})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BA=\sqrt{[-10 - 2]^2 + [y - 1]^2}\implies 13=\sqrt{(-12)^2+(y^2-2y+1)} \\\\\\ 13^2=(-12)^2+(y^2-2y+1)\implies 169=144+y^2-2y+1 \\\\\\ 169=y^2-2y+145\implies 0=y^2-2y-24 \\\\\\ 0=(y-6)(y+4)\implies y= \begin{cases} 6\\ -4 \end{cases}~\hfill A= \begin{cases} (-10~,~6)\\ (-10~,~-4) \end{cases}
