How do you solve 5x+17>5(2x+1) algebraically?
Answer:
x < 12/5
Step-by-step explanation:
First, distribute 5 among everything inside the parenthesis to get 5x + 17 > 10x + 5.
Next, subtract 5 on both sides to get
5x + 12 > 10x.
Afterwards, subtract the 5x on both sides to get 12 > 5x.
Finally, divide 5 on both sides to get 12/5 > x (You can always flip it around so that the x is on the other side btw.) Answer is written above⤴⤴⤴.
Hope this helps you :)
27. A prime factor of 2310 is chosen at random. What is the
probability that the chosen factor will be greater than 7?
Step-by-step explanation:
The prime factorization of 2,310 is 2 × 3 × 5 × 7 × 11. Since it has a total of 5 prime factors, 2,310 is a composite number.
The probability of chosen factor will be greater than 7 will be ( 1 / 5 ).
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that a prime factor of 2310 is chosen at random. The probability will be calculated as:-
The prime factorization of 2,310 is 2 × 3 × 5 × 7 × 11.
Favourable outcome = 11 = 1
Total outcomes = ( 2,3,5,7,11) = 5
Probability = ( 1 / 5 )
Therefore, the probability of chosen factor will be greater than 7 will be ( 1 / 5 ).

System of equation by using substitution
3=y+3x
-x+3y=29
Answer:
x=-2
y=9
Step-by-step explanation:
3=y+3x ---- A
-x+3y=29 ----B
step 1. rearrange equation A, so you have the "y" variable on one side
3=y+3x
-3x -3x
3-3x=y
y=3-3x ---- C
step 2. Substitute equation C into equation B in place of "y"
-x+3(3-3x)=29 ---foil
-x+9-9x=29 -- collect like terms
-10x+9=29
-9 -9
-10x=20
÷-10 ÷-10
x=-2
Step 3. Substitute x=-2 into equation C to find y
y=3-3(-2)
y=3+6
y=9
Check you answer by subsituting x=-2 and y=9 back into equation A and B

Step-by-step explanation:
Factor this into the form:
(x +/- a)(x +/- b)
As the third term is a positive and the second is negative, we know that the two operators are subtract:
(x - a)(x - b)
Find the factors of 56:

Last year, prices increased due to inflation. This year inflation caused prices to go up again. After the second increase, the price for a certain item became 6 times the original. What was the percent increase of the second increase if the first increase was 50%?
The second percentage increase in price is 300%.
Inflation is when there is a persistent rise in the general price levels in an economy. Inflation leads to an increase in the prices of goods and services.
Let's assume that the price of an item is $100.
This year prices are 6 times the original price. This means that prices are $600 ($100 x6).
Increase in prices after the 50% increase = (1.5 x 100) = $150.
Percentage increase in price so that price is now $600 = $600 / $150 - 1 = 3 = 300%

Temperature
Temperature is the degree of hotness or coldness in a place. There are different temperature scales such as Celsius, Fahrenheit etc.
To convert from Fahrenheit to Celsius, use:
C = (F - 32) * 5/9
Given that F = 122, hence:
C = (122 - 32) * 5/9 = 50°
The value of 122°F in °C is 50°C

In the game of Scrabble, each player begins by drawing 7 tiles from a bag containing 100 tiles. There are 42 vowels, 56 consonants, and 2 blank tiles in the bag. Cait chooses her 7 tiles and is surprised to discover that all of them are vowels. Can we use a binomial distribution to approximate this probability?
Considering the hypergeometric variable, it is found that since the population size is less than 20 times the sample size, the binomial distribution cannot be used.
The tiles are chosen without replacement, hence, the hypergeometric distribution is used.
The population is composed by the 100 tiles.The sample is composed by 7 tiles.The hypergeometric distribution can be approximated to the binomial if the population size is at least 20 times the sample size.
[tex]\frac{100}{7} = 14.28 < 20[/tex]
Hence, the binomial distribution cannot be used.
