Answer:

\frac{b}{c} =\frac{b}{c}

bc=cb

It is an example of commutative property.

Step-by-step explanation:

The given expression

\frac{b}{c} =\frac{b}{c}

By cross multiplying we can write given expression as

b\times c=c\times b

<h3>Commutative property: commutative property states that order does not matter.</h3><h3> In addition , commutative property</h3>

  a+b=b+a

<h3>In multiplication , commutative property </h3>

a\times b = b\times a

We can write commutative property in multiplication

        ab=ba

Therefore, by using commutative property  then we get

         bc=cb

Hence, the given expression is an example of commutative property.

Bruce’s hourly wage increased from $25.50 to $30.60. What rate of increase does this represent?
sleet_krkn [62]

Hello !

<u>((new value - old value) / old value) × 100 </u>

((30.60 - 25.50) / 25.50) × 100

= (5.10/25.50) × 100

= 0.2 × 100

= 20

→ The rate of increase is 20%

Solving \frac{4-5i}{2+3i} we get -\frac{7}{13}-\frac{22i}{13}

Option A is correct.

Step-by-step explanation:

We need to find the result of \frac{4-5i}{2+3i}

We need to remove i from the denominator. For removing i Multiplying and dividing by 2-3i:

\frac{4-5i}{2+3i}*\frac{2-3i}{2-3i}

Solving:

=\frac{4-5i*2-3i}{2+3i*2-3i}\\=\frac{4(2-3i)-5i*(2-3i)}{(2)^2-(3i)^2}\\=\frac{8-12i-10i+15i^2)}{4-9i^2}\\We\,\,i^2=-1\\=\frac{8-12i-10i+15(-1))}{4-9(-1)}\\=\frac{8-12i-10i-15}{4+9}\\=\frac{8-15-12i-10i}{13}\\=\frac{-7-22i}{13}\\=-\frac{7}{13}-\frac{22i}{13}

So, solving \frac{4-5i}{2+3i} we get -\frac{7}{13}-\frac{22i}{13}

Option A is correct.

Mrs. Rogers sold 48 out of 80 crafts at the fair. What percent of her crafts did she sell? ~Plz answer like ASAP!!thank you :))
Gre4nikov [31]

Answer:

38.4

38.4 is 48% of 80

Step-by-step explanation:

What is 48% of 80?

Y is 48% of 80

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 48% * 80

Converting percent to decimal:

p = 48%/100 = 0.48

Y = 0.48 * 80

Y = 38.4
