19-3x=21+x
Add 3x to both sides.
19-3x+3x=21=x+3x
19=21+4x
Subtract 21 from both sides.
19-21=21+4x-21
-2=4x
Divide both sides by 4.
-1/2=x

Hope this hleped!

Subtract 19 from both sides
-3x=2+x

Subtract x from both sides
-4x=2

Divide both sides by -4
x=-1/2

Final answer: x=-1/2

Two 6-sided dice are rolled. what is the probability that the sum of the two numbers on the dice will be greater than 9?

AVprozaik [17]

What combination of numbers are needed in order to get a sum of 9?
It can be:
• First die is 6 , second die is 3
• First die is 3 , second die is 6
• First die is 4 , second die is 5
• First die is 5 , second die is 4

How many possible combinations are made? Yep, 4 possible combinations.

Recall the formula for probability
$Probability = \frac{Number of desired outcomes}{Number of all possible outcomes}$

There are 4 desired number of outcomes.
How about the total possible outcomes?
• How many numbers are possible to appear when the first die is rolled?
Answer: 6
• What about the second die?
Answer: Also 6
• Therefore, total possible outcomes = 6 * 6 = 36 outcomes

You can now solve for the probability.

$Probability = \frac{4}{36} = \frac{1}{9}$ or approximately 11.11%

If an English teacher marks 220 essays in 28 hours 36 minutes, how long on average does it take to mark one essay?

Xelga [282]

First, let us break down 28 hours 36 minutes into minutes.

Number of minutes taken to grade 220 essays = (28 x 60) + 36 = 1680 + 36 = 1716 minutes

Now, we can find the average time taken to grade an essay by dividing the time taken to grade 220 essays by 220.

Average amount of time taken to grade an essay = $\frac{1716}{220}$ = 7.8 minutes, or 7 minutes and 48 seconds

denis-greek [22]

100% = 1.00 is the cost of the jeans itself
6% = 0.06 is the sales tax to be added
let "cost of jeans" be represented by x
so you will get an expression
(1.00 + 0.06) x + 8.95 = Total Cost
