Jane multiplies her number by three and subtracts 2.
katrin [286]

Answer:

Let the number they chose be 'x'.

Result of Jane = 3x -2

Result of Elliot = 2x+3

Given that,

The product of their result = 110

or, (3x-2)(2x+3) = 110\\or, 6x^{2} +9x-4x-6 = 110\\or, 6x^{2} +5x - 6 = 110\\or, 6x^{2} +5x - 6-110 = 0\\\\or, 6x^{2} +5x - 116 = 0\\or, 6x^{2} +29x - 24x - 116 = 0\\or, x (6x +29) -4(6x+29) = 0\\or, (x-4)(6x+29) = 0\\i.e. x=4 or x=\frac{-29}{6} \\So,~ the ~number ~they~ chose~was ~either ~4 ~or ~\frac{-29}{6}

If a basketball player consistently shoots 80% from the free throw line and she takes 25 free throw shots throughout the course
faltersainse [42]
The formula for percentage is:

is/of = %/100

In the given problem,
is = ?
of = 25
% = 80

We get,

?/25 = 80/100

"is" is unknown so let "is" be "x"

x/25 = 80/100

We have to cross multiply.  Meaning, we will multiply the numerator of one fraction by the denominator of the other fraction. Therefore,

100x = (80)(25)
100x = 2000
x = 20

The answer is 20.  The basketball player is expected to make 20 free throw shots out of 25 in the entire game.

Molodets [167]

Answer:

Pilar va a pagar en total por el coche 14209.84€.

Step-by-step explanation:

Pilar ha comprado un coche, da una entrada y lo quiere pagar en 12 meses.

Cada mes va a pagar 600,82€. Como lo quiere pagar en doce meses, luego de finalizado ese tiempo el precio pagado se calcula como:

12 meses* 600,82€ por mes= 7209,84€

Por otro lado, Pilar ha dado al principio una entrada de 7000€. Entonces, el total a pagar por el coche es calculado como:

7000€ + 7209,84€= 14209.84€

<u><em>Pilar va a pagar en total por el coche 14209.84€.</em></u>
