Let x rep cost of dvd in $
so the cost of tv is 3x
and x + 3x = 1132
4x=1132
x=1132/4
x= 283 and 3x=3(283)=849
Answer:
In economics, a portfolio is a term for a specific set of stocks, bonds, shares, and other securities owned by an investor. In general, the investor seeks to compile and diversify a portfolio of securities that offers maximum profitability and at the same time is diverse, in order to minimize possible risks. In general, these types of portfolios are considered efficient, as they do not leave the investment risk tied to a single factor. However, these two goals often go against each other, so the composition of the portfolio means a certain compromise.
15 cm, as 1 and 3 are too small, 75 is too big, and 15 is just average

let AB = E
⇒ (AB) (7 m) = (1.75 m) ( BC + AB)
(AB) (7 m) = (1.75 m) (1.5 m + AB)
= 2.625 m² + (1.75 m ) (AB)
(AB) (7 m - 1.75 m) = 2.625 m²
∴ AB = 2.625 m² ÷ (5.25 m)

⇒ the length of AB is 0.5 m</span>
Maybe you should try 18 it might work because it will all be equal
