Equation to find number:
- 3 = 
Number's value: n = 
Step-by-step explanation:
Let n be the unknown number.
The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be
.
The difference of three and the reciprocal of a number (
) would be
- 3.
The quotient of 20 and the number (n) would be
.
So, with this information we've gathered so far, we can come up with an equation to find what the number equals.
Equation:
- 3 = 
To find what the number equals we must solve the equation.
Answer:
The length is 99 cm
Step-by-step explanation:
The perimeter of a rectangle is
P = 2 (l+w)
310 = 2( l+56)
Divide each side by 2
310/2 = 2/2( l+56)
155 = l+56
Subtract 56
155-56 = l+56-56
99 = l
