Answer:
She has 6 apples
Step-by-step explanation:
3-2 is 1 then add 5 which is 6:))
Because of the relatively large coefficients {9, 42, 49}, applying the quadratic formula would be a bit messy. Instead, I've chosen to "complete the square:"
9x^2 + 42x + 49 = 0 can be re-written as 9 [ x^2 + (42/9)x ] = -49
Dividing both sides by 9, we get [ x^2 + (42/9)x ] = - 49/9
Completing the square: [ x^2 + (42/9)x + (21/9)^2 - (21/9)^2 ] = -49/9
[ x + 21/9 ]^2 = 441/81 - 441/81 = 0
Then [ x + 21/9 ] = 0, and x = -21/9 (this is a double root).
5x+6=2(2x-3)
5x-4x+6=-6
X=-6-6
Answer:x=-12
A school is in session for 6 hours each day. Each class is allotted 3/4 hour, including passing time. How many classes can be fit into the school day?
<span>6 / (3/4) = </span>
<span>6 * (4/3) = 24/3 = 8 classes</span>
