Answer:

x=7

Step-by-step explanation:

Simplifying

4 + -7x + 10 = 15 + -6x + -8

Reorder the terms:

4 + 10 + -7x = 15 + -6x + -8

Combine like terms: 4 + 10 = 14

14 + -7x = 15 + -6x + -8

Reorder the terms:

14 + -7x = 15 + -8 + -6x

Combine like terms: 15 + -8 = 7

14 + -7x = 7 + -6x

Solving

14 + -7x = 7 + -6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6x' to each side of the equation.

14 + -7x + 6x = 7 + -6x + 6x

Combine like terms: -7x + 6x = -1x

14 + -1x = 7 + -6x + 6x

Combine like terms: -6x + 6x = 0

14 + -1x = 7 + 0

14 + -1x = 7

Add '-14' to each side of the equation.

14 + -14 + -1x = 7 + -14

Combine like terms: 14 + -14 = 0

0 + -1x = 7 + -14

-1x = 7 + -14

Combine like terms: 7 + -14 = -7

-1x = -7

Divide each side by '-1'.

x =7

Simplifying

x = 7

A motorcycle is traveling at a constant speed of 45 miles per hour. how many feet does it travel in 6 seconds? remember that 1 m

Fantom [35]

Answer:

The total number of feet travelled by the motorcycle is 396 feet

Step-by-step explanation:

Using the constant speed relationship with the distance:

v = s/t

From the above equation the distance travelled will be:

s = v * t (i)

We are given with the v, that is:

v = 45 miles per hour

Converting in to feet per second.

v = (45 * 5280)/3600 feet / s

v = 66 feet per second

Now, put that v and t in equation (i)

s = 66 * 6

s = 396 feet

The population of a bacteria colony is growing exponentially, doubling every 6 hours. If there are 150 bacteria currently presen

marusya05 [52]

Answer:

If rounded to the nearest 10 bacteria, then it would be 500 bacteria.

Step-by-step explanation:

First multiply 150 by two in order to get 300, that leaves 4 hours to figure out. From there you can figure out the rest by seeing that 4 is 2/3 of 6. I converted it into the decimal number .66. Multiply 300 by .66 to get 198 and then add it to 300 to get 498. Then just round it up to the nearest 10 bacteria which leaves you with the final answer of 500 bacteria.
