30$ originally - 21$ paid = 9$ discount
> divide the discount by the original price, multiply by 100 to get the percent decrease.
100 x (9$ / 30$) = 30% discount
> So the shoes where on sale for 30% off the original price.
for the equation:
100 x (30-21)/30 = % decrease
The answer would be the first option
because the size of the shape is not altered
Answer:
Here we can go for trial and error,
Taking x=6
So equation will be 6*6-18 which gives 18
and is not equal to 54
So it's, not 6
Trying 12
6*12-18
Which is 54 and so correct answer is x=12
Let's solve your equation step-by-step.<span><span><span> 44−1</span>+<span>7q</span></span>=106</span>
Step 1: Simplify both sides of the equation.<span><span><span> 44−1</span>+<span>7q</span></span>=106</span><span>
</span><span>Simplify: (Show steps) </span><span><span><span><span>44+</span>−1</span>+<span>7q</span></span>=106</span><span><span><span>(<span>7q</span>)</span>+<span>(<span>44+<span>−1</span></span>)</span></span>=106 </span>(Combine Like Terms)<span><span><span>7q</span>+43</span>=106</span><span><span><span>7q</span>+43</span>=106</span>
Step 2: Subtract 43 from both sides.<span><span><span><span>7q</span>+43</span>−43</span>=<span>106−43</span></span><span><span>7q</span>=63</span>
Step 3: Divide both sides by 7.<span><span><span><span><span>7q</span>7</span></span></span>=<span><span><span>637</span></span></span></span>
