<h2>75</h2>

Beginning with an "If-then" statement ⇣

<em>If </em><em>2/5 = 30 </em><em>then</em><em> 1/5 = 15</em>

Now we have 1/5, let's make it 1 by multiplying x5.

<em>15 x 5 = </em><em>75</em>

Can anyone help? There’s 2 solutions. (50 points + brainliest)
Andreyy89
Domain:

x-1\neq0\\\\\boxed{x\neq1}

As we see in a numerator we have a square, so (3x+1)^2 is always 0 or more. Now, there are two possibilities:

1. (3x+1)^2>0

We divide two numbers, and first one is positive, so the result will be also positive (it canot be 0 in this case) when x-1\ \textgreater \ 0. So:

 x-1\ \textgreater \ 0\\\\\boxed{x\ \textgreater \ 1}

2. (3x+1)^2=0

In this case the result wil be 0 (we have ≥ 0 in our inequality, so it will be a solution).

(3x+1)^2=0\\\\3x+1=0\\\\3x=-1\qquad|:3\\\\\\\boxed{x=-\dfrac{1}{3}}

So the solution to this inequality is:

\boxed{x=-\dfrac{1}{3} \qquad\vee\qquad x\ \textgreater \ 1}

Ivan drove 804 miles in 12 hours.<br> At the same rate, how many miles would he drive in 9 hours?
kykrilka [37]
804 miles/12 hours = 67 miles

Which means that Ivan drove 67 miles per hour

67 miles*9 hours = 603 miles

Which means that in 9 hours Ivan can drive 603 miles if he drives at a constant speed of 67 miles per hour.
