APLICACIÓN 6 Si compro un televisor a S/ 12000 y lo quiero vender ganando el \( 20 \% \). ¿A cuánto lo debo vender? \( \begin{array}{ll}\text { a) S/ } 14400 & \text { b) } 12200 \\ \text { c) } 22000 & \text { d) } 1240 \\ \text { e) } 14440 & \end{array} \)

The Turners have purchased a house for \( \$ 150,000 \). They made an initial down payment of \( 20 \% \) and secured a mortgage with interest charged at a rate of \( 3.5 \% / \) year on the unpaid balance. Assume that the loan is amortized over 30 years. (Round all answers to the nearest cent.) a) How much is the down payment? b) how much is borrowed from the bank? c) What monthly payment will the Turners be required to make? d) What will be their total price of the house? e) How much of the total amount is interest?

What is the greatest common factor (GCF) of 12 and 18?

\( \frac{24}{60} \) con denommador is

Check whether the ordered pair \( (5,6) \) is a solution of the system. \( -2 x+4 y=-14 \) \( 3 x+y=21 \) a no

(1 point) Find all solutions \( x \) to each of the following equations. Separate multiple answers with commas. Use no solution or none if there are no solutions. \( 3 e^{10 x}=5 e^{8 x} \) has solutions \( x=\square \) \( 7 e^{10 x}=4 e^{10 x}+5 e^{8 x} \) has solutions \( x=\square \) \( 7 e^{10 x}=4 e^{10 x}+20 e^{8 x} \) has solutions \( x=\square \) \( \frac{e^{10 x}}{e^{10 x}+5 e^{8 x}}=\frac{4}{7} \) has solutions \( x=\square \)
