Hey there!:

4r -3 + 6s - 8r - (4s - 6)

*distribute parentheses :

=  - ( 4s ) - ( - 6 ) 

Apply minus  - plus rules

- ( - a )  = a  ;  - ( a ) = - a

 =  - 4s + 6


4r -3+ 6 s - 8r -4s + 6 = 

Group like terms :

=4r - 8r + 6s - 4s -3+6

Add similar elements: 4r - 8r= - 4r

-4r + 6s - 4s- 3+6

6s - 4s =  2s

-4r  + 2s  - 3 + 6


Add/Subtract the numbers :

-3 + 6  = 3

Therefore:

= 2s +3 - 4r

hope this helps!

andrew11 [14]

Answer:

Step-by-step explanation:

speed = distance/time

so renaldo speed = 3.2/0.5 = 6.4miles/hr (since time taken is 1/2 hr)

now after 1 hr of his appoinment i.e at 5:30pm he took bus whose speed is same as before i.e 6.4 miles/hr

now time taken to cover this 4.8 miles = 4.8/6.4 = 3/4 hr (since time = distance /speed )

3/4 hr = 3/4 * 60 = 45 minutes

so he reached at 6:15pm . so he will be on time.

a bag contains 5 red marbles, 3 yellow marbles, and 2 blue marbles. Once a marble is drawn, it is not replaced.what is the proba
Aleksandr-060686 [28]
5 red, 3 yellow, and 2 blue....for a total of 10 marbles

P(first one being blue) = 2/10 which reduces to 1/5
not replaced
P(second one is blue) = 1/9...because u already pick a blue, meaning there is only 1 left, and there is one less marble, so there is a total of 9 marbles.

P(both events happening) = 1/5 * 1/9 = 1/45 <==

The value of y is directly proportional to the value of x when x=512 y=128 what is the value of y when x=64
luda_lava [24]
Answer: y=16
explanation: y=128 when x=512, so to get the value of y, you need to divide 512/64=8. dividing 512(x) by 8 times gets 64, so you need to divide 8 on the other side(y). 128/8=16. hope this helped!
