Anna inherits $70000 and decides to invest part of it in an education account for her daughter and the rest in a 5 year CD. If t

TEA [102]

E = amount she put for Education

CD = amount she put for a Certificate of Deposit.

so, whatever those amounts are, we know that all she got is 70,000 bucks total, so E + CD = 70000.

how much is three times the CD? well, 3*CD or 3CD.

how much is 10,000 more than that? well 3CD + 10000.

since we know that the amount on Education was 10000 more than three times the CD, then E = 3CD + 10000.

$\bf \begin{cases}
E+CD=70000\implies \boxed{CD}=70000-E\\
E=3CD+10000\\
------------------\\
E=3\left( \boxed{70000-E}\right)+10000
\end{cases}
\\\\\\
E=210000-3E+10000\implies 4E=200000\implies E=\cfrac{200000}{4}
\\\\\\
E=50000$

how much was it invested in the CD? well, CD = 70000 - E.

ASAP! HELP!!!

The measure of each of the angles ∠P,∠Q,∠R, ∠S are 45°,72°,135° and 98° respectively.

<h3>What is quadrilateral ?</h3>

A quadrilateral is a polygon having four sides. The measure of the opposite angle of quadrilateral inside circle is 180°.

From the figure:

∠P=x+15

∠Q=3x-8

∠R=?

∠S=3x+8

∠Q+∠S=180

3x-8+3x+8=180

6x=180

x=30°

∠P+∠R=180°

x+15+∠R=180

30+15+∠R=180

∠R=180-45

∠R=135°

∠P=30+15=45

∠Q=3x-8=3(30)-8=72

=135

∠S=3x+8=3(30)+8=98

Hence,the measure of each of the angles ∠P,∠Q,∠R, ∠S are 45°

,72°,135° and 98°.
