You have to give them the same denominator so multiply 11/12 by 4 and 3/16 by 3. giving you 44/48 and 9/48. then divied 44 by 9 giving you 4.8888
there for there are 4 whole 3/16 sections of the 11/12 board
<span>90/x=100/18</span>
<span>(90/x)*x=(100/18)*x - </span> multiply both sides of the equation by x
<span>90=5.55555555556*x - </span>divide both sides of the equation by (5.55555555556) to get x
<span>90/5.55555555556=x </span>
<span>16.2=x </span>
<span>x=16.2</span>
<span>18% of 90=16.2
</span><span>
</span>
Step:
58/4x54+7x21 =
783+7x21 =
783+147 =
930
Answer:
Step-by-step explanation:
We want to solve the equation:
Over the interval [0, 2π).
First, notice that this is in quadratic form. So, to make things simpler, we can let <em>u</em> = cos(x). Substitute:
Rearrange:
Factor:
Zero Product Property:
Solve for each case:
Back-substitute:
Using the unit circle:
