Mary has 20 biscuits in a tin there are 11 plain biscuits 7chocolate biscuits 2 currant biscuits sue takes at random 2 biscuits from the tin work out the probability that the 2 biscuits were not the same type?

Answer:

Explanation:

ʲ⁄₋₂ + 7 = -12

Subtract 7 From Both Sides

ʲ⁄₋₂ + 7 - 7 = -12 - 7

Simplify

ʲ⁄₋₂ = -19

Multiply Both Sides By -2

(-2) ʲ⁄₋₂ = -19 (-2)

Answer:

38

Step-by-step explanation:

Answer:

simplest form

Step-by-step explanation:

Simplest form is a method of converting the fraction to its lowest multiple.

For example, the fraction 25/100 isn't in its simplest form

Both the numerator and the denominator can be divided by 5. When divided by 5 the fraction becomes 5/20.

5/20 is still not in its simplest form because it can be divided by 5. When divided by 5, the fraction becomes 1/4.

1/4 is now in its simplest form because both the numerator and denominator cannot be divided by any other number

Answer:

the answer is 2................

Answer:

The Correct Answer Is 4

Step-by-step explanation:

So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12

count in your head, 3 6 9 12 therefore, ITS 4

here is your equation to match this:

3 x ? = 12

You probably already know this, but i simple way to figure this out is to flip the equation to

12/3 = ?

so from here you can tell that 3 goes into 12 4 times

so the equation is

3 x 4 = 12

Answer: x  =  2 /3  ,  −  1

Step-by-step explanation:

Answer:

B 1/3 then reflection across y axis then move figure 2 units to down and 1 right.

Step-by-step explanation:

The figure ABC is bigger than FED so the scale factor is less than one since we are going to ABC to FED. Let look at corresponding sides, AB and FE. AB distance is 3. FE distance is 1 so let divide

[tex] \frac{fe}{ab} [/tex]

[tex] \frac{1}{3} [/tex]

The scale factor is 1/3.

The new points are at A'(-2,0) B'(-2,1) C'(-1,0).

Then we apply reflection.

Since FED is in the 4th quadrant, we are going to reflect across the y axis.

That becomes using formula

(x,y) goes to (-x,y) when reflecting across yaxis.

A''(2,0) B''(2,1) C''(1,0)

Now we will apply the translation. We can simply just move the figure 2 units down and 1 unit to the right.

Answer:

x = 20

Step-by-step explanation:

perimeter = 2(width) + 2(length)

2(6x) + 2(3x) = 360

12x + 6x = 360

18x = 360

divide both sides by 18

x = 20

Answer:

Distance travel by Monica = 628 ft

Step-by-step explanation:

Given:

Radius of whee l = 1 ft

Number of revolution = 100

Find:

Distance travel by Monica

Computation:

Distance travel by Monica = 100[Circumference of wheel]

Distance travel by Monica = 100[2πr]

Distance travel by Monica = 100[2(3.14)(1)]

Distance travel by Monica = 100[6.28]

Distance travel by Monica = 628 ft

Answer:

8.5

Step-by-step explanation:

Answer:

x = 40

Step-by-step explanation:

x + 100 +  x = 180 {Straight line angles}

2x   + 100 = 180      {subtract 100 from both sides}

         2x = 180 - 100

         2x = 80      {Divide both sides by 2)

           x = 80/2

          x = 40

Answer:

x=40

Step-by-step explanation:

2x+100=180

2x=180-100

2x=80

x=40

The values of x and y in the following equation system are 20 and 110, respectively.

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.

given a system of equation:

30x + 4y = 1,040.....(1)

12x + 16y = 2,000...…(2)

We will solve it by using substitution method,

Multiply with 2.5 in equation (2) and subtract it from equation (1)

30x + 4y - 30x - 40y = 1040 - 5000

36y = 3960

y = 110

Substitute this value of y in equation (1)

30x + 440 = 1040

30x = 600

x = 20

Therefore, The value of x and y are 20 and 110 respectively for the given system of equation.
