a male black widow spider is half the size of a female black widow spider. together they are 21 millimeter in length. how big is a female black widow
Divide 21 by 3.
The female is 2 of those thirds.
The male is 1 of those thirds.
the solution is.......17,
To find the size of the female black widow spider, we first need to determine the size of the male black widow spider.
Let's assume the size of the male black widow spider is represented by "x" millimeters.
According to the information given, the male black widow spider is half the size of the female black widow spider. Therefore, the size of the female black widow spider would be 2x millimeters.
We are also given that together, both spiders measure 21 millimeters in length. So, we can set up the equation:
x + 2x = 21
Combining like terms:
3x = 21
Dividing both sides by 3:
x = 7
Therefore, the size of the female black widow spider (2x) would be:
2 * 7 = 14 millimeters
