5 Solve for x. 8 = 2x + 4​

Answers

Answer:

8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2

Answer:

x=2 (answer should have a positive sign.)

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

Steve flipped a coin 10 times and recorded his results in this chart.

Part C: Did Steve’s EXPERIMENTAL result match the THEORETICAL probability of a coin landing heads up? If the probabilities are not the same, explain at least one possible reason for the difference.

Answers

They are not the same but very close, the reasoning for this is that theoretical things are not 100% accurate therefore meaning that the answers with a real experiment may vary.

3/1 1/2 (3 divided by one and one-half)

to get: 2

Then multiply it by the scale factor of 4

2*4= 8

But remeber, this is only ONE side of the garden, so multiply this by 4

8*4=32  

Next we want to see the number of links it takes to build the garden
