76 82 87 93 95 98

Mean -
76+82+87+93+95+98 = 531
531/6 = 88.5

Range -
98 - 76 = 22

Median -
Because there are 6 numbers you have to find the average of the middle two
87+93 = 180
180/2 = 90

Mode -
No number is repeated so there is no mode.

One hundred divided by twice a number is ten

Ludmilka [50]

$\frac{100}{2x} = 10$

Are you trying to find x, or are you only suppose to translate it?

If you are trying to find x, you first multiply 2x on both sides

100 = 10(2x)

Divide 10 on both sides

10 = 2x

Divide 2 on both sides

5 = x
