3(5x+1)-3x=2-3(3x+1)

Answers

Answer:

x = − 4 \21

Step-by-step explanation:

Answer:

x= [tex]-\frac{4}{21}[/tex]

Step-by-step explanation:

Step 1- Distribute into the parenthesis.

(3)5x+(3)1-3x=2+(-3)3x+(-3)1

Step 2- Multiply.

15x+3-3x= 2-9x-3

Step 3- Add common variables.

(15x-3x)+3=(2-3)-9x

12x+3=-1-9x

Step 4- Add 9x to both sides.

12x+3= -1-9x

+9x         +9x

21x+3= -1

Step 5- Subtract 3 to both sides.

21x+3= -1

     -3   -3

21x= -4

Step 6- Divide both sides by 21.

21x= -4

21    21

x= [tex]-\frac{4}{21}[/tex]

100 POINTS PLUS BRAINLIEST FOR CORRECT ANSWER! Sam wants to take his phone and his Nintendo Switch with him on his upcoming road trip. His parents tell him they will be leaving in a half-hour and Sam realizes he forgot to charge both of the devices. He hurries to plug in each device to get as much battery life as possible before they leave. When he plugged in his phone it only had a 5% battery life and his Nintendo Switch had 20%. He periodically checked back to see the progress of each device and kept notes of their progress. Use the given information above and Sam’s notes below to find out how much battery life each device will have when it is time to leave. Also, if the device will not be fully charged how much extra time should Sam ask his parents to delay their departure time by?
Sam’s Notes: After 6 minutes his phone had 20% and after 9 minutes it had 27.5%. After 10 minutes his Nintendo Switch had 32% and after 15 minutes it had 38%.

Answers

when you leave the Nintendo switch will have 96% and the phone will have 84%,he should ask his parents for about 20 more minutes.

Answer:

when they leave, the phone would be charged 80% and the nintendo 36%. They would need to delay the road trip for 76.8 more minutes for the nintendo to fully charge and 50 minutes for the phone to fully charge

F(x) = 3x-1. g(x)=x2+1. What is (f+g)(x)?

Answers

Answer:

x^2 + 3x

Step-by-step explanation:

Just add like terms:

(f + g)(x) = 3x - 1 + x^2 + 1.  Notice that you must use " ^ " or equivalent to denote exponentiation.

(f + g)(x) =      3x - 1 + x^2 + 1 = x^2 + 3x + 1 - 1

(f + g)(x) =      3x - 1 + x^2 + 1 = x^2 + 3x
