Geometry help with number 18!
lora16 [44]
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36

jim and lisa had a total of $300. After jim boughy a jacket with 2/3 if her money,she had $90 less than lisa. find the cost of t
Yuri [45]

Answer:

$84

Firstly, what we must do, is establish a system of equations:

\frac{2}{3}J = L -90

J + L = 300

Due the circumstances, it is decided we will use the method of substitution:

\frac{2}{3}J = L - 90

\frac{2}{3}J + 90 = L

          ↓

J + \frac{2}{3}J + 90 = 300

Now, we solve the 2-variable equation above:

J + \frac{2}{3}J + 90 = 300

J + \frac{2}{3}J = 300 - 90

J + \frac{2}{3}J = 210

J(3) + (\frac{2}{3}J)(3) = 210(3)

3J + 2J = 630

5J = 630

J = \frac{630}{5}

\bf~J = 126

Now, we must see how much money each one of them had & the price of the jacket:

Now we know that Jim had $126. In other words, $126 is \frac{3}{3} of his money (total money).

So, if Jim has $126, which corresponds to \frac{3}{3} of his money, \frac{2}{3} of his money is:

\frac{126}{3} = 42

126 * \frac{2}{3} = 42 + 42

\bf~126 * \frac{2}{3} = 84

Hope it helped,
