What is multiplication?

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

The symbols cross (×), asterisk (*), and dot (·) are used to denote multiplication. You most frequently utilize the cross when writing in your notebooks. In computer languages and algebra, the asterisk and dot are both utilized (higher mathematics).

Given:

When 2 pipes fill a pool together, they can finish in 5 hrs,

One of the pipes fills half the pool then the other takes over to finish filling the pool, it will take them 18 hrs

1 / 2 of pool = 9 hrs as given

full pool = 9 × 2 = 18 hours

Therefore, The time taken to fill the pool if it were working alone is 18 hours.

x-2.5y=12.5
-x+2.3y=11.9

Answers

Answer: the answers are x = -292.5 and y = -122

Step-by-step explanation:

Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.

For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.

After that, we get the 2 equations as

2.3x-5.75y = 28.75

-2.5x+5.75y = 29.75

then by adding the 2 equations we get

-0.2x = 58.5

and by dividing 58.5 by -0.2 we get

x = -292.5

substituting the value of x in any equations above we get

y = -122

Solve the following equation: x + 25 = 30

solve the equation -2(x-5)=-14

Answers

Answer:

x=12

Step-by-step explanation:

-2(x-5)=-14

x-5=-2/-14

x-5=14/2

x-5=7

x=5+7

x=12

X =12. Multiply it out. -2x +10= -14. -2x=-14-10. -2x= -24. Divide both sides by -2. Hope this helps!

The answer is 1133.33 i got it from go ogle so blame me if i got it wrong blame go ogle  can i have Brainliest

Step-by-step explanation:

Answer:

66 2/3

Step-by-step explanation:

The way to solve this is The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid. Note: The volume of a pyramid varies slightly depending on the polygonal base.

What i did was i first tried to do 17 x 20 x 10 which game 3400 but when i remembered that V=1/3 x base area x height which would be 1/3 x 17 x 20 = 113 1/3 but if the base was 10 it would be 1/3 x 10 x 20 = 66 2/3. so i think the base is 10 and the answer would be 66 2/3

the inequality is 92.05=18+0.05x

x= the number of minutes he uses

subtract 18 from both sides, which makes it

74.05=0.05x

divide both sides by 0.05 and that makes it

x= 1,481

so he used 1,481 minutes
