If P is between L and A, PL = 6x + 24, PA = 12x - 6 and LA = 30x - 18, then x = ______ and LA = ___&&

levacccp [35]

To solve this problem, we have to use the definition of segment addition.

$LA=PL+PA$

Then, we replace the given expressions

$30x-18=6x+24+12x-6$

Now, we solve for <em>x</em>.

$\begin{gathered} 30x-6x-12x=24-6+18 \\ 12x=36 \\ x=\frac{36}{12} \\ x=3 \end{gathered}$ <h2>Hence, x = 3.</h2>

Let's find LA:

$30x-18=30\cdot3-18=90-18=72$ <h2>Hence, LA measures 72 units.</h2>

In planning her retirement, Liza deposits some money at 4.5% interest, with twice as much deposited at 5%. Find the amount depos

AlekseyPX

Let

x ----> amount deposited at 4.5%

y ----> amount deposited at 5%

we have that

y=2x----> equation A

4.5%=0.045

5%=0.05

0.045x+0.05y=1,595 ----> equation B

solve the system

substitute equation A in equation B

0.045(x)+0.05(2x)=1,595

solve for x

0.045x+0.10x=1,595

0.145x=1,595

x=11,000

Find y

y=2(11,000)=22,000

<h2>The amount deposited at 4.5% was $11,000 and the amount deposited at 5% was $22,000</h2>
