The answer is:
940
----
70
Here's my work:
<span><span><span>949/70</span></span>=<span><span><span><span>70t/</span>70</span></span>
-</span></span>Cross-multiply.<span><span><span><span>
949/70</span></span></span>=<span><span><span><span>70t/</span>70</span></span></span></span><span><span><span>
(949)</span>*<span>(70)</span></span>=<span><span>70t</span>*<span>(70)
</span></span></span><span>66430=<span>4900t</span></span>
-Flip the equation.
<span><span>4900t</span>=66430</span>
-Divide both sides by
4900.<span><span><span><span><span>4900t
</span>4900</span></span></span>=<span><span><span>66430
4900</span></span></span></span><span>t=<span><span>94970</span></span></span>
Hope this helps:)
Answer:

Hi there! I don't know how you solve these, but at school we solve them like this:
x^2-2x=0
<span>
Δ = b^2-4ac
a = 1; b = - 2; c=0
<span>Δ = 4-0=4
X1,2 = -b+ or - rad </span><span>Δ / 2 a
X1,2 = 2 + or - 2 / 2
X1 = 2 and X2 = 0/2 = 0</span>
So the solutions are 2 and 0
I hope it helped!
