Answer:

520 out of 800 students ride the bus

Step-by-step explanation:

Given

$Proportion = 65\%$

$Students = 800$

Required

Determine the number of students $that\ ride\ the\ bus$

To do this, we simply multiply the proportion by the total number of students.

i.e.

$Bus = Proportion * Students$

$Bus = 65\% * 800$

Express the percentage as decimal

$Bus = 0.65* 800$

$Bus = 520$

saw5 [17]

Answer:

$x^2 + x -12$

Step-by-step explanation:

If the solutions are x=-4 and x=3, then it must have factors (x+4)(x-3). Assuming there is no GCF or leading coefficient other than 1, multiply with FOIL to find the standard form.

$(x+4)(x-3)\\x^2 + 4x -3x -12\\x^2 + x -12$
