Answer:

X = -8 and X = 2

Step-by-step explanation:

X^2 + 6X - 6 = 10

Bring the 10 over:

X^2 + 6x - 16 = 0

From here, either use the quadratic formula or

manual factorization by finding its roots:

Manually:

(X + 8)(X - 2) = 0

Equate each factor to 0 you will get:

X + 8 = 0 and X - 2 = 0

Solutions are -8 and 2 respectively.

May runs around a 4 m track at a consistent speed of 250 m/min. how many minutes does it take me to complete for lapse of the tr

Nookie1986 [14]

Answer:

It takes May 6 minutes and 24 seconds to run 4 laps and 1 minute and 36 seconds per lap

Statement and question:

May runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take May to complete 4 laps of the track?

Source:

Previous question that can be found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of May = 250 meters per minute

Length of the track = 400 meters

2. How many minutes does it take May to complete 4 laps of the track?

Let's answer the question calculating the total distance and the time it took Mary to run around the track, this way:

Total distance = 4 * 400 = 1,600 meters

Time it takes May to run 1,600 meters = 1,600/250

Time it takes May to run 1,600 meters = 6.4 minutes

6.4 minutes = 6 minutes + 0.4 * 60 seconds = 6 minutes and 24 seconds

Time it takes May to run one lap = 6.4/4 = 1.6

1.6 minutes = 1 minute + 0.6 * 60 seconds = 1 minute and 36 seconds

Answer:

40.35

Step-by-step explanation:

First find the discount

97 * 60%

97 *.6 = 58.2

Subtract the discount to find the new price

97-58.20 =38.80

Next find the tax

38.80 * 4%

38.80 * .04

1.55

We add the tax to the sales price

38.8+1.55

40.35

Madison works as a salesperson at an electronics store and sells phones and phone accessories, and makes a fixed commission for

Jet001 [13]

Answer:

Price of each phone: $\$9$

Price of each accessory: $\$3.5$

Step-by-step explanation:

Let be "p" the price in dollars of each phone and "a" the price in dollars of each accessory.

Set up a system of equations:

$\left \{ {{8p+10a=107} \atop {4p+23a=116.50}} \right.$

You can use the Elimination Method to solve the system.

Multiply the second equation by -2 and add both equations:

$\left \{ {{8p+10a=107} \atop {-8p-46a=-233}} \right.\\............................\\-36a=-126\\\\a=\frac{-126}{-36}\\\\a=3.5$

Substitute the value of "a" into the first equation and solve for "p":

$8p+10(3.5)=107\\\\8p=107-35\\\\p=\frac{72}{8}\\\\p=9$

Answer:

FG= 20

Step-by-step explanation:

The reason FG and BC are not equal is because they are only similar. That's what that squiggle means. Hope this helps. Please name me Brainliest
