3 times the difference of a number and 4 equals 12. Find the number.

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:

C

Step-by-step explanation:

Answer:

theyre correct

Step-by-step explanation:

Answer:

Pink Trapezium = 30   as 30 x 1 = 30

Purple Diamond = 2    as 2 x 2 = 4

Green Moon = 7.5     as it shares the line with 4 it goes 4 x 7.5 = 30

The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.

When we show the values see below. We have 30 also for the second line so both lines are equivalent

Step-by-step explanation:

I would multiply as addition is just too easy.

Pink Trapezium is 1 x 30 = 30  = 30/1 = 30 value

Purple diamond = 2 x 2 = 4  = 4/2 = 2 value

Green Moon is 30/4 = 7.5 value

The answer is 8/27 beacuse you must moltiplicate 2 for 2 and after for 2. Then 3 for 3, and after for 3

Step-by-step explanation:

The image of the polygon after a reflection in the line y=x is has vertices at A'(-3, 6), B'(-2, 1) and C'(1, 4) as shown in the diagram attached.

Transformation is the movement of a point from the initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.

Reflection is the flipping of a figure. If a point A(x, y) is reflected about the line y = x, the new point would be at A'(y, x)

Given the polygon with vertices at A(6, -3), B(1, -2) and C(4, 1). The image of the polygon after a reflection in the line y=x has vertices at:

A'(-3, 6), B'(-2, 1) and C'(1, 4)

The image of the polygon is attached

Median is 18

Step-by-step explanation:

Firstly you have to fine y by using your mean

Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15

22+18+2y+1+10+20 over 5 =15

71+y over 5 =15

Cross multiple

71+y=75

y=4

22,18,9,10, 20

Rearrange

9,10,18,20,22

The median is 18

3 x 3 = ?

Step-by-step explanation:

3 x 3 = 9 yesyes

1/3 x 1/3 = 1/9

now we add, right? 9/1 ( same as 9 ) + 1/9 = ?

does it want it in fraction, decimal, or whole?

Answer:

9 1/9 is the answer

Step-by-step explanation:

1/3 to the power of 2 becomes 1/9

3 to the power of 2 becomes 9

[tex]\frac{1}{9} + 9[/tex]

whole numbers always go over a 1

[tex]\frac{1}{9} + \frac{9}{1}[/tex]

make 9/1 have the same denominator as 1/9 by multiplying the top and bottom with 9

[tex]\frac{1}{9} + \frac{81}{9}[/tex] [tex]= \frac{82}{9}[/tex]

the simplify 82/9
