Answer:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.
Step-by-step explanation:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.
Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.
Let x represent the number of bull shark teeth.
So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.
18 = 6 + 8 + x
18 = 14 + x
subtracting 14 from both sides, we have
18 - 14 = 14 - 14 + x
4 = 0 + x
4 = x
x = 4
So, the number of bull shark teeth is 4.
Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is <em>not</em> 42 - it's 41. So, Sarah is incorrect.
Answer:
4.609 meters
Step-by-step explanation:
The hypotenuse is the ladder because it is the slanted side. 3m is one of the other side lengths
A^2 + B^2 = C^2
3^2 + B^2 = 5.5^2
9 + B^2 = 30.25
30.25 - 9= B^2
21.25= B^2
4.609=B
Answer:
51.41 g
