Distrivute 0.2 to x and +50 and you get 0.2x+10-6  now for the other side we do the same and we get 1.2x+8 or an easier way...  Let's solve your equation step-by-step.<span><span><span>0.2<span>(<span>x+50</span>)</span></span>−6</span>=<span>0.4<span>(<span><span>3x</span>+20</span>)</span></span></span>Step 1: Simplify both sides of the equation.<span><span><span>0.2x</span>+4</span>=<span><span>1.2x</span>+8</span></span>Step 2: Subtract 1.2x from both sides.<span><span><span><span>0.2x</span>+4</span>−<span>1.2x</span></span>=<span><span><span>1.2x</span>+8</span>−<span>1.2x</span></span></span><span><span><span>−x</span>+4</span>=8</span>Step 3: Subtract 4 from both sides.<span><span><span><span>−x</span>+4</span>−4</span>=<span>8−4                </span></span><span><span>−x</span>=<span>4  now you divide by negative x (technically it is -1x=4 so your answer is x=-4</span></span>

Find the function value of cos^2 (7pi/8)
Kamila [148]
\cos^2\dfrac{7\pi}8=\dfrac12\left(1+\cos\dfrac{7\pi}4\right)
=\dfrac12+\dfrac12\cos\left(-\dfrac\pi4\right)
=\dfrac12+\dfrac12\cos\dfrac\pi4
=\dfrac12+\dfrac1{2\sqrt2}
=\dfrac{\sqrt2+1}{2\sqrt2}
=\dfrac{2+\sqrt2}4
