A. Not a proper counterexample as 3 and 5 aren't the same number. We can rule out choice A.
B. We can rule out choice B since we're not multiplying here
C. We are multiplying the same value with itself but the result is even. We can rule this out.
D. This is a proper counter example. We have the same number (5) multiplied by itself leading to a result that is not even. It contradicts the initial claim.
Answer: Choice D
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
<u>2/5 x + 1/3 x = 22</u>
First of all, I've been answering so many of these things lately that I'm
getting really tired of 'x'. Let's call the unknown number ' Q ' instead.
<u>2/5 Q + 1/3 Q = 22</u>
Multiply each side by 5 :
2Q + 5/3 Q = 110
Multiply each side by 3 :
6Q + 5Q = 330
Add the like terms on the left side:
11Q = 330
Divide each side by 11 :
<u>Q = 30</u> .
Answer:
490 km
Step-by-step explanation:
350 km in 5 h
350 ÷ 5 = 70 km in an hour
70 × 7 = 490 km in 7 hours
