Let's solve your equation step-by-step.
<span><span><span>4s</span>−<span>4<span>s2</span></span></span>=1
</span>Step 1: Simplify both sides of the equation.
<span><span><span>−<span>4<span>s2</span></span></span>+<span>4s</span></span>=1
</span>Step 2: Subtract 1 from both sides.
<span><span><span><span>−<span>4<span>s2</span></span></span>+<span>4s</span></span>−1</span>=<span>1−1
</span></span><span><span><span><span>−<span>4<span>s2</span></span></span>+<span>4s</span></span>−1</span>=0
</span>Step 3: Factor left side of equation.
<span><span><span>(<span><span>−<span>2s</span></span>+1</span>)</span><span>(<span><span>2s</span>−1</span>)</span></span>=0
</span>Step 4: Set factors equal to 0.
<span><span><span><span>−<span>2s</span></span>+1</span>=<span><span><span>0<span> or </span></span><span>2s</span></span>−1</span></span>=<span>0
s = 1/2</span></span>
Answer 20
Step by Step: None
$2.50 for 3.2 oz. is the better buy. multiply 1.2 by 8/3 to get 3.2 oz, which you will have to multiply $1.00 by 8/3 to get $2.67. So $1.00 for 1.2 oz is the equivalent of $2.67 for 3.2 oz.
Answer:
The value of y is 68° .
Option (C) is correct .
Step-by-step explanation:
As the figure given in the question be as follow .
Now apply angle sumproperty in the triangle .
(According to this property the total sum of the triangle is 180°.)
y° + (y - 12)° + 56 ° = 180 °
y + y - 12 + 56 = 180
2y + 44 = 180
2y = 180 - 44
2y = 136
y = 68°
Therefore the value of y is 68° .
Option (C) is correct .
