Answer:
(1) 10x + 40
Step-by-step explanation:
5(2x+8)
= 5×2x + 5×8
= <u>10x + 40 (Ans)</u>
About 400 zebras live at the game reserve.
The proportion would be
30/150 = 80/x
This is because 30 zebras are tagged out of 150 in one area. We know that they tagged 80 total zebras out of x total zebras.
To solve this, cross multiply:
x*30 = 150*80
30x = 12000
Divide both sides by 30:
30x/30 = 12000/30
x = 400
