Name the property the equation illustrates (ab)3=a(b3)

1 answer:

3 0

The answer to this rests on knowing that there are four properties of multiplication (which your teacher will likely expect you to know...):

These are:
1. commutative
2. associative
3. multiplicative identity
4. distributive

I won't define each of these -- they should be in your notes or textbook. Look them up.

In this case, we are multiplying three terms together -- on the left hand side the parentheses mean to multiply a and b first, then multiply that by 3. On the right hand side, we multiply b times 3 first, and then multiply the product by a.

This would be an example of the associative property of multiplication: when three or more factors are multiplied together, the product is the same regardless of how the factors are grouped.

Hope this helps!

Good luck

Answer:

C. 11

Step-by-step explanation:

First, find the value of "x" by solving the first equation. You need to move every other number to the other side of "x". When you move a number, you have to do the opposite operation to both sides.

5x + 6 = 10 The opposite of +6 is -6.

5x + 6 - 6 = 10 - 6 Subtract 6 from both sides

5x = 10 - 6 The "6" on the left cancelled out. Simplify the right side

5x = 4 The opposite of multiply by 5 is divide by 5

5x/5 = 4/5 Divide both sides by 5

x = 4/5 Value of "x"

Substitute the value of "x", which is 4/5, in the "x" for the second equation.

10x + 3

= 10(4/5) + 3 Multiply 10 and 4/5

= $\frac{10*4}{5}$ + 3 Combine into the numerator

= $\frac{40}{5}$ + 3 Divide the top by the bottom

= 8 + 3 Add

= 11 Value of second equation

Therefore the value of 10x + 3 is 11.

How to solve this maths equation??? pls help me, its urgent!!! asap

Answer:

x = $\frac{3wyz}{4wz+wy-2yz}$

Step-by-step explanation:

Given

$\frac{2}{w}$ + $\frac{3}{x}$ - $\frac{4}{y}$ = $\frac{1}{z}$

Multiply through by wxyz to clear the fractions

2xyz + 3wyz - 4wxz = wxy ( subtract wxy from both sides )

2xyz + 3wyz - 4wxz - wxy = 0 ( subtract 3wyz from both sides )

2xyz - 4wxz - wxy = - 3wyz ( factor out x from each term on the left side )

x(2yz - 4wz - wy) = - 3wyz ( divide both sides by (2yz - 4wz - wy )

x = $\frac{-3wyz}{2yz-4wz-wy}$ ( multiply numerator/ denominator by - 1 )

x = $\frac{3wyz}{4wz+wy-2yz}$

Answers:

A) Ray QS or Ray QR
B) Line segment QS or SQ
C) Plane QSR
D) Line QS or RQ

=======================================================

Explanation:

Part A)

When naming a ray, always start at the endpoint. This is the first letter and we'll start with point Q.

The second letter is the point that is on the ray where the ray aims at. We have two choices S and R as they are both on the same ray. That's why we can name this Ray QS and Ray QR.

--------------------

Part B)

A segment is named by its endpoints. The order of the endpoints doesn't matter so that's why segment QS is the same as segment SQ. To me, it seems more natural to read from left to right, so QS seems better fitting (again the order doesn't matter).

--------------------

Part C)

When forming a plane, you need 3 noncollinear points. The term "collinear" means the points all fall on the same line. So these three points cannot all fall on the same straight line. In other words, we must be able to form a triangle of some sort.

So that's how we get the name "Plane QSR". The order of the letters doesn't matter.

--------------------

Part D)

To name a line, we just need to pick two points from it. Any two will do. The order doesn't matter. So that's how we get Line QS and Line RQ as two aliases for this same line. It turns out that there are 6 different ways to name this line.

Line QR
Line QS
Line RQ
Line RS
Line SQ
Line SR
