A holiday decoration involves blue and white lights.The ratio of blue lights to white lights is 3 to 2 . The box the decoration came in stated that the number of blue lights was 114 but didn't give the number of white lights or the total number of lights.
Answer:
a. 76 b. 190
Step-by-step explanation:
a. Number of white lights
Since the ratio of blue lights to white lights is 3 to 2 and the number of blue lights is 114, it follows that 3 : 2 = 114 : x where x is the number of white lights.
So, 3/2 = 114/x
cross-multiplying,
3x = 114 × 2
3x = 228
x = 228/3
x = 76
b. Total number of lights
So, the total number of lights is thus number of blue lights + number of white lights = 114 + 76 = 190
How many expressions can you find using and that have a value of 12 a=6 b=4 c=-2
Answer:
Step-by-step explanation:
Some of the expressions that can be derived that have the values of 12 are:
i. 2a = 2 x 6
= 12
ii. 3b = 3 x 4
= 12
iii. (b + c) x a = (4 - 2) x 6
= 2 x 6
= 12
iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)
= 8 + 4
= 12
v. [tex]b^{2}[/tex] - [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)
= 16 - 4
= 12
vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4
= 16 - 4
= 12

Step-by-step explanation:
Solve for x in the first equation.
x=2+4y/3
5x+8y=−1
Replace all occurrences of x with 2+4y/3 in each equation.

Thomas has two bags, one bag with 6 yellow and 5 red marbles, and one with 2 green and 4 blue marbles. If his friend Nick pulls one marble from each bag, what is the probability of him getting one red and one blue marble?
The probability of him getting one red marble from 5 red marbles in one bag and one blue marble from 4 blue marbles in the other bag is 4/11.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of marbles in first bag = 11
Yellow marbles = 6
Red marbles = 5
Number of marbles in the second bag = 6
Green marbles = 2
Blue marbles = 4
The probability of him getting one red and one blue marble.
= [tex]\frac{^5C_1}{^{11}C_1} \times\frac{^4C_1}{6^C_1}[/tex]
= 5/11 x 4/5
= 4/11
Thus,
The probability of him getting one red and one blue marble is 4/11.

Step-by-step explanation:
You can insert different values of x to find y
For example:
x = 4
Plug in x into the equation
y = -1/2(4) + 5
y = -2 + 5
y = 3
So your point will be (4, 3)
If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.
