Given:

[tex]z=5-9i[/tex]

[tex]w=6+i[/tex]

To find:

The expression that shows the first step in finding the quotient of [tex]\dfrac{z}{w}[/tex].

Solution:

According to the question,

[tex]\dfrac{z}{w}=\dfrac{5-9i}{6+i}[/tex]

First, we need to multiply and divide the conjugate of denominator, i.e., 6-i, to find the quotient.

[tex]\dfrac{z}{w}=\dfrac{5-9i}{6+i}\times \dfrac{6-i}{6-i}[/tex]

Therefore, the correct option is A.

Step-by-step explanation:

This is a simple equation. All you need to do is divide 18 by 36.

18/36 = 0.5

Answer:

$0.5

(50 cents)

Step-by-step explanation:

Just divide how much it costs (18) by the number of items bought (36) and you'll find how much it costs per-item.

$18 ÷ 36 = $0.5

So $0.5 (50 cents) is your answer.

Answer:

false, it's the opposite so its doesn't have the same amount, negative or positive.

True.

The absolute value of opposite numbers is the same as the number because the absolute value is always positive.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number = x

The opposite of x is -x.

Now,

The absolute value of -x.

= |-x|

= x

We are getting the number back.

Thus,

The absolute value of opposite numbers is the same as the number.

Answer:

1.44 meters

Step-by-step explanation:

Given that:

As per the nurse, height of Sarah = 1.4 meters

Let us have a look at the number and let us analyze each digit.

Here is only one digit after the decimal place which is the tenths place.

It is given that Sarah measured the height herself.

And also added a digit at the Hundredth place i.e. a digit after 4 will be added.

1.4_  --- In place of _ , a digit will be added.

As per the question statement, Digit at the Hundredth place will be equal to  the digit at the Tenth's place.

Therefore, the height measured by Sarah herself will be equal to 1.44 meters.

Answer:

50 blocks

Step-by-step explanation:

First of all, you need to label you're proportions, which can be mm/blocks.

Then, for 1 block, it is 20 mm because the block is 2 cm, which is equal to 20 mm. So for you're proportion, it is 20 mm/1 block.

Finally, you need to find the total amount of blocks that equals 1000 mm. So you can multiply the 20 mm by 50 to get the 1000 mm. What you do at the top, you do at the bottom, so you also have to do 1 block by 50 to get 50 blocks

So for you're final answer/proportion, it is mm/blocks = 20/1 = 1000/50 and you're final answer is 50 blocks

The last one is an easy way to tell that the slope is not -2 1/5 because it is positive

Step-by-step explanation:

When a line goes up from left to right, it's positive. If it goes down from left to right, it's negative.

Answer:

x = 10.

Step-by-step explanation:

The longest side , the hypotenuse = x + 3 because the lengths of the sides  are positive.

So, by Pythagoras:

(x + 3)^2 = (x - 5)^2 + (x + 2)^2

x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4

0 = 2x^2 - x^2 - 10x + 4x - 6x + 29 - 9

x^2 - 12x + 20 = 0

(x - 10)(x - 2) = 0

x = 2, 10.

x cannot be 2 because that would make one side =  2- 5 = -3 so the answer is x = 10.

Answer:

x=7

Step-by-step explanation:

We want to get the variable "x" alone to get our answer. So.

1. combine like terms

x+x+2+3x-6=31

like terms in equation: (left side)

x, x, 3x= 5x       (equation: x+x+3x)

2, -6= -4             (equation: 2-6)

so, this is what the equation would look like with our new answers:

5x-4=31

2. add 4 to both sides

5x-4+4=31+4

(on left side of equation, the -4 and +4 cancel each other out, leaving the 5x alone)

5x=35

3. divide 5 from both sides, to get the "x" alone

5x/5=35/5

so, our answer would be:

x=7

Answer:

37

Step-by-step explanation:

use inverse operations to solve ,

16 - 11 = g

g = 5

if g = 5 then , 5 times 5 is 25 , add 12 to 25 and get 37

*please name brainliest if you can :)

The value of the expression 5g + 12 is 37, when g equals 5.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.

Given A equation g + 11 = 16.

g = 16 - 11.

g = 5.

Now, 5g + 12

= 5×5 + 12.

= 25 + 12.

= 37.

Answer:

B

Step-by-step explanation:

Here, we simply want to know who will reach the 6-foot mark sooner

Mathematically, we need to get the slope from the graph

Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds

So what this mean is that, in 4 seconds, the 6 ft mark will be reached

This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs

Now compare this with what Stephano has, which is 2.25 ft/ s

we can see that stephano is traveling at a better speed and will reach the 6 ft mark first

So the correct option is B

Answer:

1 1/3

Step-by-step explanation:

We simplify it into 3 1/6 - 1 5/6.

Since 5 cannot subtract from 1, we convert 3 1/6 into 2 7/6 because it is equivalent to 3 1/6, and subtract 1 5/6 from that fraction to get 1 1/3.

Answer:

QT = 45

Step-by-step explanation:

ST = 65

SP = 26

RQ = 30

QT = 4x - 3

Given that ∆STR is similar to ∆PTQ, therefore:

[tex] \frac{ST}{PT} = \frac{RT}{QT} [/tex]

Plug in the values

[tex] \frac{65}{65 - 26} = \frac{30 + (4x - 3)}{4x - 3} [/tex]

Solve for x

[tex] \frac{65}{39} = \frac{30 + 4x - 3)}{4x - 3} [/tex]

[tex] \frac{5}{3} = \frac{27 + 4x}{4x - 3} [/tex]

Cross multiply

[tex] 5(4x - 3) = 3(27 + 4x) [/tex]

[tex] 20x - 15 = 81 + 12x [/tex]

Collect like terms

[tex] 20x - 12x = 81 + 15 [/tex]

[tex] 8x = 96 [/tex]

Divide both sides by 8

[tex] x = \frac{96}{8} [/tex]

[tex] x = 12 [/tex]

✅QT = 4x - 3

Plug in the value of x

QT = 4(12) - 3 = 48 - 3

QT = 45

Answer:

Unit Price at Grocery Mart = $1.50

Unit Price at Baldwin Hills = $1.33

Step-by-step explanation:

Unit price in this case will be the price divided by number of pounds

Let u1 be the unit price of Grocery Mart and u2 be the unit price at Baldwin Hills

Given

[tex]s_1 = 2.99\\w_1 = 2\\s_2 = 3.99\\w_2 = 3[/tex]

The unit price for Grocery Mart is:

[tex]u_1 = \frac{s_1}{w_1}\\= \frac{2.99}{2}\\= 1.495[/tex]

Rounding off to nearest penny

u1 = $1.50 per lbs

Unit price for Baldwin Hills is:

[tex]u_2 = \frac{s_2}{w_2}\\=\frac{3.99}{3}\\=1.33[/tex]

u2  = $1.33 per lbs

Hence,

Unit Price at Grocery Mart = $1.50

Unit Price at Baldwin Hills = $1.33
