Multiply (2 + 3i) with (3 – 4i)

Answer:

Non fiction : Total number of books

= 14 : 42

= 1:3

Step-by-step explanation:

Total number of books = 42 books

Non fiction books = 14 books

The ratio of the number of non-fiction books to the total number of books is :

Non fiction : Total number of books

= 14 : 42

Further simplified

= 1:3

Answer:

$88.9

Step-by-step explanation:

First, you have to calculate the total cost of the items by adding up the results of multiplying the price of each item for its quantity:

Total cost=(29*2)+(16*3)+21

Total cost=58+48+21

Total cost=127

Now, you have to calculate 30% of that total and subtract that amount from the total cost:

127*30%=$38.1

127-38.1=$88.9

According to this, the answer is that the total cost of these items is $88.9 if the store is offering a 30% discount.

Answer:

[tex]\mathrm{A)\:}-4[/tex]

Step-by-step explanation:

Start off by solving for [tex]x[/tex]:

[tex]6x-4-4=9x-6,\\6x-8=9x-6,\\-3x=2,\\x=-\frac{2}{3}[/tex]

Now plug in [tex]x=-\frac{2}{3}[/tex] in [tex]3x-2[/tex]:

[tex]3(-\frac{2}{3})-2=-2-2=\fbox{$\mathrm{A)\:}-4$}[/tex].

Answer:

A -4

I've done this before.

Answer: 1,200

Step-by-step explanation:

lets split it like this first

now lets start with the first one 15*20=300

now the second one 45*10=450

now the third one 35*10=350

now the last one 10*10 i think i caint see the one number=100

now add all them together= 1,200

Answer:

[tex]2x + 18 = 15x + 33 - 8x \\ 2x + 18 = 7x + 33 \\ 2x - 7x = 33 - 18 \\ - 5x = 15 \\ x = - 3[/tex]

Step-by-step explanation:

Jim 1= 60 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

after Jim 1 took the spoons to the blacksmith he broke 27 spoons which means

Jim 1= 60-27 which leaves him with 33 spoons.

and now

Jim 1= 33 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

3 normal spoons outta 33 spoons which means he used 11 spoons per each spoon

and now

Jim 1= 3 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

so finally, all the Jims have 697 spoons in total.

a bit tuff...lol

have a great day mr/mrs. Jim creator :)

Answer:

5/6

Step-by-step explanation:

The equation for slope is

(difference in y) / (difference in x)

So:

6-1/10-4

5/6

So the slope is 5/6

Answer:

-759

Step-by-step explanation:

Any number powered by 0 equals to 1, so the equation then becomes 1 × 5x - 789, but then x is 6, so it's 30 - 789, which is -759.

Answer:

1.65 km or 33/20 km per minute, 16.5 km or 33/2 km ( for the second question)

Step-by-step explanation:

There's 60 minutes in an hour, so just divide 99 by 60, then you'll get either 1.65 or 99/60 which is simplified to 33/20. And for the second question, multiply the answer from the first question by 10.

Answer:

Answer:

68

Step-by-step explanation:

Because it's going up 15 every 2 hours so it would go from 50 to about 65 so 68.

Answer: A

Step-by-step explanation:

The equation [tex]y=\frac{2}{3}x-1[/tex] is in slope-intercept form([tex]y=mx+b[/tex]).  For a line to be parallel to another, it must have the same slope.  The slope of the line given is 2/3.  Thus, simply plug in 2/3 for the slope to get: [tex]y=\frac{2}{3} x+b[/tex].  Then, because the line passes through -6, 6, plug those values in for x and y, respectively.  [tex]6=\frac{2}{3} *-6+b[/tex]

[tex]6=-4+b[/tex]

[tex]10=b[/tex]

Thus, the equation of the line is [tex]y = \frac{2}{3} x+10[/tex], or A

Answer:

  20 meters

Step-by-step explanation:

The single hash mark on AB matches the single hash mark on AC, so AB = AC. AC is marked as 20 meters, so AB is 20 meters.

Answer:

There's 3 answers: the third, fourth, and the sixth one. 1  2  3

                                                                                           4  5  6

Step-by-step explanation:

The expression in the question gets simplified to p-6, and so does the third one, fourth one is just itself, and the sixth one also simplifies to p-6.

Answer
