Because there are 1000 millimeters in one meter, we can divide 1000 by 8 to see that 125 spiders that are 8mm long would fit side by side on a meter stick.
About 31%
You add all of the numbers up to find out how many cans there are overall. Then take 80(cans of tuna) / overall cans and get around 31%.
Answer: The number is 23
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
a number increased by 11 is equal to twice the number decrease by 12
x+11=2x-12
Add 12 on both sides
x+11+12=2x-12+12
x+23=2x
Subtract x on both sides
x+23-x=2x-x
x=23
