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

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

The ratio of boys to girls in a school is 4:5. How many boys are in the school if there are 720 students.

scZoUnD [109]

Answer: 320 boys

Step-by-step explanation: you would first take the total number (720) and divide it by the total number shown in the ratio (5+4=9)

720/9= 80

You would then take 80 and multiply it by 4 because that is the number representing the boys

80*4= 320

Question 14(1 point)Find the rate of change of Pete's height from 3 to 5 years.17.Time (years) 123 4 15 16Height/in.) 27 35 37 4

kupik [55]

The rate of change of Pete's height from 3 to 5 years can be determined as,

$\begin{gathered} \frac{\Delta H}{\Delta t}=\frac{H_5-H_3_{}}{5-3} \\ =\frac{45-37}{2} \\ =\frac{8}{2} \\ =4 \end{gathered}$

Thus, the required rate of change from 3 to 5 years is 4 in/year.
