So, Christian has a collection of 18 shark teeth. He identified them as 6 tiger shark teeth, 8 sand shark teeth, and the rest as
svetoff [14.1K]

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.

HELP 99 PTS=50 PTS Theresa has two brothers, Paul and Steve, who are both the same height. Paul says he is inches shorter than t
iren [92.7K]

Answer:

Theresa is 58.82 in tall

Step-by-step explanation:

Let 

x----------> Paul and Steve heights

y----------> Theresa height


we know that

1 1/2-------> 3/2---> 1.5

1 1/3-------> 4/3----> 1.33

 Paul says he is 16 inches shorter than 1 1/2 times Theresa's height

x=1.5y-16-------> equation 1


Steve says he's 6 inches shorter than 1 1/3 times Theresa's height

x=1.33y-6------> equation 2


equals 1 and 2

1.5y-16=1.33y-6

1.5y-1.33y=-6+16

0.17y=10----------> y=58.82 in


x=1.5y-16------> 1.5*(58.82)-16------> x=72.24 in


the answer is

Theresa is 58.82 in tall
