Answer:

18

Step-by-step explanation:

3x + 28 = 46

Subtract 28 from each side

3x + 28 = 46

3x+28-28 = 46-28

3x=18

Divide each side by 3

3x/3 = 18/3

x = 6

Find 2x+6

2(6)+6

12+6

18

Hey there!


3x + 28 = 46


SUBTRACT 28 to BOTH SIDES

3x + 28 - 28 = 46 - 28

CANCEL out d 28 - 28 because it give you 0

KEEPs 46 - 28 because it help solve for the x-value.


NEW EQUATION: 3x = 46 - 28


SIMPLIFY IT!

3x = 18


DIVIDE 3 to BOTH SIDES

3x/3 = 18/3

CANCEL out: 3/3 because it give you 1

KEEP: 18/3 because it give you the x-value.

NEW EQUATION: x = 18/3


SIMPLIFY IT!


x = 6


Now that we have your x-value we can substitute it into the equation of: 2x + 6


SIMPLIFYING:

2x + 6

= 2(6) + 6

= 12 + 6

= 18


Thus, your answer is: 18


Good luck on your assignment & enjoy your day!

Evaluate each function. Step by step.
Usimov [2.4K]

Answer:

Substitute what t and n equals to in the equation and just solve using algebra.

So number 2, plug in -3 where ever the variable N is located in and solve.

g(-3) = 3(-3)^2+3+2(-3)  ---> g(-3) = 27+3-6 ---> g(-3) = 24 That's the answer for 2.

For 1

plug in -5 into the t variable and solve.

k(t) = -2 |3(-5)| + 2 Since the || is between the 3 and 5, answer will be positive.

k(t) = -2(15)+2

k(t) = -28
