Answer:The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.

Answer:
<h2>149 times.</h2>
Step-by-step explanation:
Let n be the number we are looking for.
The we have to solve this equation:
1999 - 7n = 1701 - 5n
⇔ 1999 - 1701 = 7n - 5n
⇔ 298 = 2 n
⇔ n = 298/2
⇔ n = 149
<u><em>Verification</em></u> :
1 999 - 7×149 = 956
1 701 - 5×149 = 956
Answer:
67% and subtracted
Step-by-step explanation:
11/2 * -11/4 = (11*-11) / 2*4 = -121 / 8
= -15 1/8 answer
-2 1/4 * -4 1/2
= -9/4 * -9/2
= 81/8
= 10 1/8 answer
