Answer: x = 21

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8x−2=6+10(x−5)

8x+−2=6+(10)(x)+(10)(−5)(Distribute)

8x+−2=6+10x+−50

8x−2=(10x)+(6+−50)(Combine Like Terms)

8x−2=10x+−44

8x−2=10x−44

Step 2: Subtract 10x from both sides.

8x−2−10x=10x−44−10x

−2x−2=−44

Step 3: Add 2 to both sides.

−2x−2+2=−44+2

−2x=−42

Step 4: Divide both sides by -2.

−2x / -2 = -42 / -2

x=21

Answer:

x = 21

Step-by-step explanation:

8x - 2 = 6 + 10(x - 5)

Step 1: Distribute the right side of the equation ("6 + 10(x - 5)") so it'll be easier to find x.

8x - 2 = 6 + 10x - 50

8x - 2 = 10x - 44

Step 2: Subtract 8x from both sides

8x - 2 = 10x - 44

<u>-8x         -8x</u>

-2 = 2x - 44

Step 3: Add 44 to both sides to get 2x alone.

-2 = 2x - 44

<u>+44       +44</u>

42 = 2x

Step 4: Divide both sides by 2 to get x alone

<u>42</u> = <u>2x</u>

2      2

x = 21

When the turnpike littered the toll, traffic increased from 1,500 cars per day to 2,700
umka21 [38]

Answer:

  80%

Step-by-step explanation:

The percentage change between two numbers can be calculated as ...

  percentage change = ((new value)/(old value) -1) × 100%

  = (2700/1500 -1) × 100% = (1.80 -1) × 100% = 80%

Traffic volume increased 80%.

The equation x^3+x^2+ax-4=0 has one root equal to -2. Find the value of a.​
Vedmedyk [2.9K]

Answer:

a = - 4

Step-by-step explanation:

Given x = - 2 is a root then f(- 2) = 0

f(x) = x³ + x² + ax - 4, thus

f(- 2) = (- 2)³ + (- 2)² - 2a - 4 = 0, that is

f(- 2) = - 8 + 4 - 2a - 4 = 0, thus

- 8 - 2a = 0 ( add 8 to both sides )

- 2a = 8 ( divide both sides by - 2 )

a = - 4
