Answer:

1) N = 2. 2) -7/3

Step-by-step explanation:

6 = 3n

6/3 = n

2 = n

n = 2

-3 = 3t + 4

3t + 4 = -3

3t = -3 - 4

3t = -7

T = -7/3

A bowl has 9 green grapes and 13 grapes. Henry randomly chooses a grape, and eats it, and then choose a another grape What is th

Sunny_sXe [5.5K]

Answer:

$\frac{72}{462}$ or $\frac{12}{77}$ (simplified)

Step-by-step explanation:

Based on the information provided within the question it can be said that in order to calculate the probability of both grapes being green we need to find the probability of each grape being green separately and then multiply those probabilities together

In the first choice, there are a total of 22 grapes (9+13), 9 of which are green. Therefore the probability of the first chosen grape being green is $\frac{9}{22}$

In the second choice,since we removed one grape there is now a total of 21 grapes (22-1), 8 of which are green. Therefore the probability of the second chosen grape being green is $\frac{8}{21}$

Now we multiply both probabilities together to calculate the probability that both grapes are green in a sequence.

$\frac{9}{22} * \frac{8}{21} = \frac{72}{462} or \frac{12}{77}$

in parallelogram ABCD, AB=(6x-2) feet DC=(3x+13) feet and AD=5 feet. Find the number of feet in the perimeter of the parallelogr

sweet [91]

Answer:

66 feet

Step-by-step explanation:

Parallelograms have 2 pair of parallel sides that are congruent to each other.

In parallelogram ABCD, we can say:

AB = DC

and

BC = AD

AB and DC are given, and they are equal. So we can say:

AB = DC

6x - 2 = 3x + 13

Now we can solve for x:

6x - 2 = 3x + 13

6x - 3x = 13 + 2

3x = 15

x = 15/3

x = 5

So,

AB = 6x - 2

AB = 6(5) - 2 = 28

So, DC = 28

We are also given AD = 5, so BC = 5 as well [since AD = BC]

Now, we know the length of all 4 sides.

The perimeter is the sum of all 4 sides. Hence,

Perimeter = 28 + 28 + 5 + 5 = 66 feet

Choose the system of equations which matches the following graph:

MAXImum [283]

Parallel lines...means ur equations will have the same slope and different y int's.

x - 2y = 8....-2y = -x + 8....y = 1/2x - 4...slope is 1/2, y int is -4
2x + 4y = 12...4y = -2x + 12....y = -1/2x + 3...slope is - 1/2, y int is 3
not this one...different slopes

x - 2y = 8...slope is 1/2, y int is -4
2x - 4y = 12...-4y = -2x + 12...y = 1/2x - 3....slope is 1/2, y int is -3
same slope, different y int's.....these are parallel lines..but this is not ur graph because the graph has a negative slope.

x + 2y = 8....2y = -x + 8....y = -1/2x + 4..slope is -1/2, y int is 4
2x + 4y = 12...4y = -2x + 12....y = -1/2x + 3...slope is -1/2, y int is 3
same slope, different y int's...parallel lines...and ur y int's match the graph...this is ur answer <===

x + 2y = 8...slope is -1/2, y int is 4
2x - 4y = 12..slope is 1/2, y int is 3
different slopes, different y int....this has 1 solution and ur lines are not parallel...not this one

therefore, ur answer is : 3rd answer choice
