30 exceeds three times a number by 89 what is the number

Mathematics
1 answer:
Lyrx [107]2 years ago
8 0

Answer:

19.66

Step-by-step explanation:

Let x represent our unknown number

Okay so it's basically saying that 30 is greater than 3x by 89

We would represent that mathematically by:

30 - 89 = 3x

So then we just solve this like we usually would

30 - 89 = -59

-59 \div 3 = 19.666. . .

Hope this helps:)

150 more male bats need to be tagged

if you want 2/5 to be female you divide the 260 (<160+100) by 2 to get 130
then you multiply 130 by 3 to get the total amount of male bats that need to be tagged
130*3=390
then you subtract 240 from the 390 to find out how many more bats need to be tagged
390-240=150
