What is d plus 7 over d squared minus 49?
(d+7)/(d2-49)(d+7)/(d+7)(d-7)1/(d-7)

d = -196
If you get 6 wrong out of 20 questions what is your grade?
70% , which is a C. If you got 6 wrong, that means you got 14 right. 14/20 can simplify down to 7/10 (divide both the numerator and denominator by 7), and 7/10 is a 70%.
How do you get the reciprocal of the divisor?
for a integer n, we call d the divisor of n if d divides n without leaving a remainder. So, for example, 49/7=7 and 7 is a divisor or a factor of 49. ( n=49, d=7 in this case) Since 7 is the divisor the reciprocal of 7 is just 1/7. In general is n is a divisor, 1/n is the reciprocal.
What does x7 mean?
In mathematics, the symbol "x" typically represents multiplication. Therefore, "x7" means multiplying a number by 7. For example, if you have the expression 5 x 7, it would equal 35.
