_______________

-120x - 50y = -710

120x + 30y = 570

_______________

-20y = -140

y = 7

x = (570 - 30*7)/120 = 360/120 = 3

The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2,

N = d - 5

2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3

Let's see if it checks out.
n = 3
d = 8

2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.

Answer:

A

Step-by-step explanation:

Diameter = 32 in

r = 32/2 = 16 in

Surface area of sphere = 4πr²

                                      = 4 * 3.142 * 16 * 16

                                      = 3217.408

In a restaurant 72 out of 108 tables are booths. What is the ratio of tables that are booths to the total number of tables.
denpristay [2]

Answer:

The ratio of tables that are booths to the total number of tables = \frac{72}{108}

Step-by-step explanation:

The number of tables in a restaurant, p = 108

The number of table that are booths, q = 72

Then, the ratio of tables that are booths to the total numbers of tables = \frac{q}{p}

                                                                 = \frac{72}{108}
