Use the elimination method to solve the system of equations. Choose the

miss Akunina [59]

9514 1404 393

Answer:

A. (4, 12)

Step-by-step explanation:

Adding the second equation to twice the first will eliminate y.

2(10x +2y) +(3x -4y) = 2(64) +(-36)

23x = 92 . . . . . . . . simplify

x = 4 . . . . . . . . . divide by 23

This value matches choice A: (4, 12).

Tim is playing a game. His score in round 1 is 1.7 points, in round 2 is 5.1 points, in round 3 is 15.3 points, and it continues

The recursive definition for the geometric sequence is given as follows:

$a_n = 3a_{n-1}, a_1 = 1.7$

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

In which $a_1$ is the first term.

The recursive definition of a geometric sequence is given by:

$a_n = qa_{n-1}$

In this problem, we have that the first term and the common ratio are given, respectively, by:

$a_1 = 1.7, q = \frac{15.3}{5.1} = \frac{5.1}{1.7} = 3$ .

Hence the recursive definition is given by:

$a_n = 3a_{n-1}, a_1 = 1.7$

Monica [59]

Answer:

Step-by-step explanation:

Find the worst case scenario.

Worst case:

12 grape gumballs, 7 cherry gumballs, and 3 orange gumballs.

12 + 7 + 3 = 22

The answer is 22 gumballs.

Hope this helps :)

Have a great day!

zabato is thinking of a number. Three times the sum of the number and ten is the same as eight times the number. What is zabato'

gavmur [86]

Let $x$ be the number Zabato is thinking of.

$3x + 10 = 8x$
$10 = 5x$
$2 = x$

So the number is 2.
