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.

A certain bacterium splits itself into 2 identical cells in 1 day. Each of those new cells is capable of splitting itself into 2 identical cells in 1 day. So the first day there are 2 cells, the second day there are 2 x 2 cells, and so on. Write and evaluate an expression using a base and an exponent to represent the number of cells present at the end of the 7th day.

Answers

Answer:

-9x+2=-4x+12

-9x+4x+2=12

-9x+4x=12-2

-5x=10

x=-2

Step-by-step explanation:

Answer:

x= -2

Step-by-step explanation:

-2(5x-1)+x=-4(x-3)

Now, use distributive property on both sides

-10x+2+x = -4x+12

Simplify

-9x+2= -4x+12

-5x= 10

x=-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°

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

What does this data suggest about speciation. A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring. B. Speciation has occurred because breeding between the offspring and original populations would not be possible. C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area. D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.
