<AEB and <DEC are equal so:
5x-10=3x+40
5x-3x=40+10
2x=50
x=25
<AEB= 5x-10
<AEB= 5*25-10
<AEB=115

You take out a loan from the bank for $4350. The bank charges an annual simple

maksim [4K]

Answer:

He will have $4491.38 after 5 year

Step-by-step explanation

Simple Interest = (Principal × rate × time)/100

SI = (4350 × 0.65 × 5)/100

SI = 141.375

Interest after 5 years = $141.38

The total money he will have after 5 years is

$4350 + $141.38

= $4491.38

How do you solve 1/x + 1/y + 1/z = 1 for z?

garri49 [273]

Answer:

$\large\boxed{z=\dfrac{xy}{xy-x-y}}$

Step-by-step explanation:

$\dfrac{1}{x}+\dfrac{1}{y}+\dfrac{1}{z}=1\qquad\text{multiply both sides by}\ xyz\neq0\\\\xyz\cdot\dfrac{1}{x}+xyz\cdot\dfrac{1}{y}+xyz\cdot\dfrac{1}{z}=xyz\cdot1\qquad\text{simplify}\\\\yz+xz+xy=xyz\qquad\text{subtract}\ xy\ \text{from both sides}\\\\xz+yz=xyz-xy\qquad\text{subtract}\ xyz\ \text{from both sides}\\\\xz+yz-xyz=-xy\qquad\text{distribute}\\\\(x+y-xy)z=-xy\qquad\text{divide both sides by}\ (x+y-xy)\\\\z=\dfrac{-xy}{x+y-xy}\\\\z=\dfrac{-xy}{-(xy-x-y)}\\\\z=\dfrac{xy}{xy-x-y}$
