That seems an odd way of wording the question. Do you mean 81+x=90? In other words, what number can you add to 81 to get 90. You can also switch it around so 90-81=x.

81+x=90
x=90-81
x=9

A species of phytoplankton measures about 2 × 10−6 in. A grain of sand measures about 1 × 10−4 in. About how many times longer i
Gennadij [26K]

Answer:

B. 50 times greater

Step-by-step explanation:

Given;

size of phytoplankton = 2 × 10⁻⁶ in

size of sand grain = 1 × 10⁻⁴ in

Determine how many times longer the grain of sand is than the phytoplankton.

Divide the sand size by the phytoplankton size, to find out how much greater the sand is.

This can be done by equating it as follows;

2 × 10⁻⁶ (y)  = 1 × 10⁻⁴

y = \frac{1*10^{-4}}{2*10^{-6}} \\\\y = 50

Therefore, the grain of sand is 50 times greater than the phytoplankton

B. 50 times greater
