Answer:

2/7=0.285714

Step-by-step explanation:

3x/3x-1+2/x=1
3x2+2(3x-1)/xx(3x-1)=1
3x2+6x-2/xx(3x-1)=1
3x2+6x-2=xx(3x-1)
3x2+6x-2=3x2-x
6x-2=-x
6x=-x+2
6x+x=2
7x=2
x=2/7=0.285714

What is the length in feet of the base of the triangle?

worty [1.4K]

$\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ A=\frac{2}{5}\\ h=\frac{6}{5} \end{cases}\implies \cfrac{2}{5}=\cfrac{1}{2}b\left( \cfrac{6}{5} \right)\implies \cfrac{2}{5}=\cfrac{6b}{10}\implies \cfrac{2}{5}=\cfrac{3b}{5} \\\\\\ 10=15b\implies \stackrel{\textit{dividing both sides by 15}}{\cfrac{10}{15}=\cfrac{15b}{15}}\implies \cfrac{10}{15}=b\implies \cfrac{2}{3}=b$

Evan can text 96 words in 12 minutes. At this rate, how many words could he text in

san4es73 [151]

If you divide 96 by 12 you get 8. This means he texts 8 words per minute. If you then multiply 8 by 14 you get 112 which means he can text 112 words in 14 minutes.
