<span><span>(<span><span>5x</span>+7</span>)</span><span>(<span>1/5</span>)</span></span>=<span><span>(<span>8−<span>6x</span></span>)</span><span>(<span>1/5</span><span>)
</span></span></span>Simplify both sides. In order to do this you need to distribute 1/5 in each expression.
<span><span><span>(<span>5x</span>)</span><span>(<span>1/5</span>)</span></span>+<span><span>(7)</span><span>(<span>1/5</span>)</span></span></span>=<span><span><span>(8)</span><span>(<span>1/5</span>)</span></span>+<span><span>(<span>−<span>6x</span></span>)</span><span>(<span>1/5</span><span>)
</span></span></span></span><span>x+<span>7/5</span></span>=<span><span>8/5</span>+<span><span><span>−6/</span>5</span><span>x
</span></span></span><span>x+<span>7/5</span></span>=<span><span><span><span>−6/</span>5</span>x</span>+<span>8/<span>5
Now you need to add (-6/5)x to both sides. This leaves you with
</span></span></span><span><span><span>(5/11)</span>x</span>+<span>7/5</span></span>=<span>8/<span>5
Now subtract 7/5 from both sides.
</span></span><span><span>(5/11)</span>x</span>=<span>1/<span>5
Divide both sides by 5/11
x=1/11</span></span>
Answer:
So the sqrt(46) is between 6 and 7
Step-by-step explanation:
sqrt(46)
5*5 = 25
6*6=36
7*7=49
So the sqrt(46) is between 6 and 7
Answer:
5 2/3
Step-by-step explanation:
2 * 2 5/6
2 * (12+5/6)
2 * (17/6)
34/6
17/3 = 5 2/3
Answer:
-45
Step-by-step explanation:
-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.
If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.
I'm pretty sure that it is 140. Hope I helped!
