Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
A because it starts out 2 degrees less than it need to be (-2) and it needs to go up. It shouldn't go down so it isn't B or D and C starts at 2 and it isn't 98 degrees to start with.
Assuming that the equation is 3x^2+3x-6=0, then use the quadratic equation, (-b+- sqrt(b^2-4ac))/2a, with ax^2+bx+c as the original equation. so here we get (-3+-sqrt(9+72))/6 = (-3+-sqrt(81))/6 = (-3+-9)/6, = (-1+-3)/2 = 1 or -2. Plug in original to check.
Step-by-step explanation:
$112. - $30 = $82.00
$82.00
x. .08
= $6.56 sales tax
$82.00 + $6.56 = $88.56 total price after tax
