I won’t be doing all 4 of them (so that you can learn how to do it yourself successfully, without

me just giving you all the answers) but I did 11 which hopefully helps you understand?

Sorry if my handwriting’s a bit on the messy side :))

How to multiply and divide rational numbers?

lutik1710 [3]

To divide rational numbers, you turn the division problem into a multiplication problem by flipping the second rational number. Then you go ahead and multiply the tops and bottoms together to get your answer. If you can simplify your problem before multiplication, you can go ahead and do so to make your problem easier.

It is a polynomial or not write step in step

Answer:

√(3x)-2y+7

4. A yellow cab Taxi charges $5.00 flat rate in addition of $0.65 per mile. Jan has no more than $20 to spend on a ride.

gogolik [260]

Answer:

$5+0.65x\le 20$

Step-by-step explanation:

Let x be the number of miles Jan can drive in a taxi.

The cost of this ride consists of

$5.00 flat rate
$.065 per mile

So, per x miles Jan will pay $0.65x and the total cost of the ride will be

$5.00+$0.65x

Jan has no more than $20 to spend on a ride, then the total cost of his ride must be less or equal to $20. Mathematically, you can write this as

$5+0.65x\le 20$

Rainbow [258]

$a_n=(n+3)^n-1\\\\a_1=(1+3)^1-1=4-1=3\\\\a_2=(2+3)^2-1=5^2-1=25-1=24\\\\a_3=(3+3)^3-1=6^3-1=216-1=215\\\\a_4=(4+3)^4-1=7^4-1=2401-1=2400\\\\a_5=(5+3)^5-1=8^5-1=32768-1=32767$
