There would be 18 separate outcomes, since the spinner has three numbers and the dice has six numbers. Since the spinner has all odd numbers then an even number must be rolled on the dice for the answer to be odd. And since half of the numbers on a dice are even then half of the answers will be odd, aka 50%

Use substitution to solve the system. x=3y+7 and 3x-4y=16

x=
y=

Answers

First we already know x, so we can put it into the other equation like so:

3(3y+7)-4y=16

Then we can solve it.

9y+21-4y=16

5y=-5

y=-1

Then we can find x.

x=3y+7

x=3(-1)+7

x=-3+7

x=4

Hope I helped!

x = 3y + 7
3x - 4y = 16

Substituting the value of x,

3(3y + 7) - 4y = 16

9y + 21 - 4y = 16

5y + 21 = 16

5y = -5

Thus, y = -1.

Substituting the value of y,

x = 3y + 7

x = -3 + 7

Thus, x = 4.

Thus, x = 4, and y = -1

The sum of two numbers is 100. The sum of 8 and the larger number is equal to 5 times the smaller number. What is the smaller number?

Answers

Answer:

The smaller number is 18

Step-by-step explanation:

Let the numbers be $x$ and $y$ where x is the smaller number; $y\:>\:x$ .

The sum of the numbers is 100.

$x+y=100...(1)$

The sum of 8 and the larger number is equal to 5 times the smaller number.

$y+8=5x$

$\Rightarrow y=5x-8...(2)$

Put equation (2) into equation (1).

$x+5x-8=100$

$x+5x=100+8$

$6x=108$

$x=18$

Answer:

The smaller number is 18.

Step-by-step explanation:

We have given that

The sum of two numbers is 100. The sum of 8 and the larger number is equal to 5 times the smaller number.

Let x and y are two numbers.

Let y is the larger number.

x+y = 100 eq(1)

y+8 = 5x eq(2)

From eq(1), we have

y = 100-x

Putting above eq(3) into eq(2), we have

100-x+8 = 5x

108 = 5x+x

108 = 6x

x = 108/6

x = 18

Hence, the smaller number is 18.

what is the common ratio for the geometric sequence below, written as a faction? 768,480,300,187.5,...

Answers

To determine the common ratio of the geometric sequence, divide the second term with the first term. 480 divided by 768 equals 5/8. Further, the ratio of the third and second terms may be used to check the consistency of the common ratio. The ratio is also 5/8. Thus, the common ratio is 5/8.
