Answer:

the first one is

+2 +4 + 8 + 16 +32

he multiply by 2 every time he add numbers so its 65

the second one he make this

-8 -4 -2 -1

every time he Take from numbers he devide by 2

so its 5

the third one

+6 +18 + 54 + 162

every time he add he multiply by 3

ao its 162 +80 =242

the fourth one is

+33 +66 + 132 +264

he multiply by 2 every time he add

so its 267+264=531

the fiveth one is

he put the roots

2²,3²,4²,5²,6²

so the answer is 36

Step-by-step explanation:

A 65

B 5

C 242

D 531

E 36

hopefully its helpful man

Twelve less than 5 times a number is greater than or equal to 6 more than twice the number. Each inequality and number line repr

jenyasd209 [6]

Answer: x ≥ 6

Step-by-step explanation:

12 less than 5 times a number ≥ 6 more than twice the number

5x - 12 ≥ 2x + 6

Note: the word "than" switches the order of the terms.

5x - 12 ≥ 2x + 6

-2x +12 -2x +12

3x ≥ 18

÷3 ÷3

x ≥ 6

Graph: 6 -----------→ the dot is closed (filled in) since it is "equal to"

Divide. a.1 − 2i/2i b. 5 − 2i/5 + 2i c.√3 − 2i/−2 − √3i

Umnica [9.8K]

Answer:

(a) \frac{-1i}{2}-1[/tex]

(b) $\frac{20i+21}{29}$

Step-by-step explanation:

We have to perform division

(a) $\frac{1-2i}{2i}$

So after division

$\frac{1-2i}{2i}=\frac{1}{2i}-\frac{2i}{2i}=\frac{-1i}{2}-1$

(b) We have given expression $\frac{5-2i}{5+2i}$

After rationalizing $\frac{5-2i}{5+2i}\times \frac{5-2i}{5-2i}=\frac{(5-2i)^2}{25+4}=\frac{25+4i^2+20i}{29}=\frac{20i+21}{29}$

After rationalizing

$\frac{\sqrt{3}-2i}{-2-\sqrt{3i}}\times \frac{-2+\sqrt{3i}}{-2+\sqrt{3i}}=\frac{-2\sqrt{3}+7i+2\sqrt{3}}{7}=\frac{7i}{7}=i$

5/8+3/4 / -2/3 - 5/6 =

m_a_m_a [10]

Answer:

-11/12

Step-by-step explanation:

Add 5/8+3/4 (6/8) which is 11/8 and then get -2/3 - 5/6 which simplifies to -3/2

Multiply -3/2 by 4 to get it to like terms

11/8 / -12/8

Multiply and then simplify.

A washer and a dryer cost $790 combined. The washer costs $40 more than the dryer. What is the cost of the dryer?

Pepsi [2]

if the washer and dryer cost $790 then you would divide 790 by 2.

then you will get $395

then you add 40 to $395 and will get $435

so the answer is $435
