How to multiply and divide

Mathematics
1 answer:
Vikentia [17]3 years ago
8 0

Answer:

Multiplication...

Multiplication is just like adding a number to itself multiple times

For example: 3x3 is the same as 3+3+3

Division...

Division is basically splitting up a number between amother lower number, (it might be pretty difficult if you don’t know how to multiply though...)

Start by Rephrasing/re-ordering the equation (9/3 looks like 3*[?] =9)

1) Figure out what Factors equal 9 (by looking at a multiplication table or by adding up like described earlier)

2) You have your answer

(this took way too long to write and you’re probably an idiot if you’re actually in middle school...smh) I can write a different answer if you meant long division, or something else

We are given the following in the question:

Number of goals(x):         0         1           2         3          4

             Probability:      0.05     0.15     0.35     0.30     0.25

We have to find the probability that Lions will score less than 3 goals.

P(X

0.55 is the probability that Lions will score less than 3 goals.

What are the solutions to the equation e^1/4x =|4x|
Ivan

Answer:

x=0.27

Step-by-step explanation:

The given expression is

e^{\frac{1}{4}x}=|4x|

To solve this equation, we graph the functions:

f(x)=e^{\frac{1}{4}x}

and

g(x)=|4x|

From the graph, the two curves intersects at x=-0.24 and x=0.27.

But the domain of the logarithmic function is x>0

Therefore x=0.27

If 3x + 5y = 2 and 2x - 4y = 20, what is 5x - y?
gavmur [86]

Answer:

= 298/11

Step-by-step explanation:

3x + 5y = 2 | ×2 |

2x - 4y = 20 | ×3 |

6x + 10y = 4

6x - 12y = 60

____________--

22y = -56

y = -56/22

y = -28/11

3x + 5y = 2 | ×4 |

2x - 4y = 20 | ×5 |

12x + 20y = 8

10x - 20y = 100

_____________+

22x = 108

x = 108/22

x = 54/11

5x - y

= 5(54/11) - (-28/11)

= 270/11 + 28/11

= 298/11

25. Save the simultaneous equations 2x-y=4;x+y=5​
Helen [10]

Answer:

x = 3

x + y = 5

y = 5 - x

2x - (5 - x) = 4

2x + x - 5 = 4

3x = 9

x = 3
