5x - 4 + x + 8 + 2x
Answer:
8x + 4
Step-by-step explanation:
Simplified
group like terms: (+5x + 1X + 2x) = 8x (-4 + 8) = 4 add the positive sign so you can get an equation: +4, so your simplified expression would be 8x + 4
y=2x+1
How do I put this equation in order pair for a table
Answer:
I think you would have to draw lines like is the graph book, you will see that they have two axes which is the y and the x.You will then have to fix in numbers and indicate the y= 2x+1.

Patryk has 7 cards.
There is a number on each card.
2 3 4 5 6 7 8
Patryk takes two of the cards at random.
He works out the product of the numbers on the two cards.
Work out the probability that the product is an odd number.
Answer:
Probability that the product is an odd number = [tex]\frac{1}{7}[/tex]
Step-by-step explanation:
Given - Patryk has 7 cards. There is a number on each card. 2 3 4 5 6 7 8
Patryk takes two of the cards at random. He works out the product
of the numbers on the two cards.
To find - Work out the probability that the product is an odd number.
Proof -
As we know that Product of two numbers is odd iff both the numbers are odd.
So, we have to find the probabilty that both the card that Patryk choose is odd
Now,
Total number of cards = 7
Total number of odd cards = 3
So, Probability = ³C₂ / ⁷C₂
= [tex]\frac{3!}{2! (3-2)!}. \frac{2! (7 - 2)!}{7!}[/tex]
= [tex]\frac{3!}{2! (1)!}. \frac{2! (5)!}{7!}[/tex]
= [tex]\frac{3!}{(1)!}. \frac{ (5)!}{7.6.5.4.3!}[/tex]
= [tex]\frac{ 5.4.3.2.1}{7.6.5.4}[/tex]
= [tex]\frac{1}{7}[/tex]
∴ we get
Probability that the product is an odd number = [tex]\frac{1}{7}[/tex]

Answer:
11.8
Step-by-step explanation:
18% of 10 so more the decimal only one time because you only have one 0 and you get 1.8. ok then 1.8 to 10 =11.8
The book cost $11.8 when the book store increases its prices by 18%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A book cost $10 at one book store which is 100% of its price.
Now, The book store increases its prices by 18%.
Therefore, The new price of the book is (100 + 18) = 118% of $10 which is,
= (118/100)×10.
= 1.18×10.
= $11.8

If you toss a coin and spin the spinner, what is the probability of landing on heads and spinning blue?
Answer:
Step-by-step explanation:
There are two sides on a coin, heads and tails. So, the probability of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.
The required probability of landing on heads and spinning blue is 3/4.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
There are two sides to a coin, heads, and tails.
So, the probability of flipping heads is going to be half, as there is one option out of the two options that you will flip a head.
As for spinning blue, there are three choices that are blue out of the four color options given.
So, the required probability = favorable outcomes / total outcomes
So, the required probability = 3/4
Hence, the probability of spinning blue would be 3/4.
