Hi there! :)

Answer:

x=-6

*The answer must have a negative sign.*

Step-by-step explanation:

First, you divide by -2 from both sides of an equation.

$\frac{-2x}{-2}=\frac{12}{-2}$

Then, you divide by the numbers from left too right.

$12/2=6$

It change positive to negative sign.

Final answer is x=-6

I hope this helps you!

Have a nice day! :)

Answer:

0.2287

Step-by-step explanation:

The computation of the probability that the automated manufacturing system runs for more than 18 hours without a failure is shown below:

P(X > 17) = 1 - P(X < 17)

= 1 - [1 - e^-18 ÷ 12.2]]

= 1 - [1 -0.228684984 ]

= 0.2287

Cristiano is saving money to buy a bike that costs $189, He saved $99 so far. He plans on saving $10 each week. In how many week

yuradex [85]

Answer:

Cristiano will have enough money to buy bike in 9 weeks.

Step-by-step explanation:

Given:

Cost of the bike = $189

Money saved = $99

Money saving each week = $10

We need to find the number of weeks will he have money to buy bike.

Solution:

Let the number of weeks be 'x'.

Now we can say that;

Money saved plus money saving each week multiplied by number of weeks is equal to cost of the bike.

framing in equation form we get;

$99+10x=189$

Subtracting both side by 99 using subtraction property of equality we get;

$99+10x-99=189-99\\\\10x=90$

Dividing both side by 10 using division property of equality we get;

$\frac{10x}{10}=\frac{90}{10}\\\\x=9\ weeks$

Hence Cristiano will have enough money to buy bike in 9 weeks.
