There are two numbers whose sum is 64. The larger number subtracted from 4 times the smaller number gives 31. Find the numbers.
There are two numbers whose sum is 64. The larger number subtracted from 4 times the smaller number gives 31. Then the numbers are 45 and 19
Solution:Given that, There are two numbers whose sum is 64.
Let the number be a and b in which a is bigger.
Then, a + b = 64 ------ eqn (1)
The larger number subtracted from 4 times the smaller number gives 31.
4 x b – a = 31
4b – a = 31 ----- eqn (2)
We have to find the numbers.
So, from eqn (2)
a = 4b – 31
Subatitute a in (1)
4b – 31 + b = 64
On solving we get
5b = 64 + 31
5b = 95
b = 19
So, b = 19, then eqn 1
a + 19 = 64
On simplification,
a = 64 – 19
a = 45
Hence, the two numbers are 45 and 19

Step-by-step explanation:
2/1 6/7
2/ 13/7
2/1*7/13
14/13
1 1/13
The division of '2' by '1 6/7' involves the conversion of the mixed number to an improper fraction, after which it becomes '2 * 7/13'. This simplifies down to '14/13' or '1 1/13'.
Explanation:To calculate the division of '2' by '1 6/7', we first have to convert '1 6/7' to an improper fraction. '1 6/7' equals '13/7' when simplified. So, now the task is to divide '2' by '13/7'. In the division of fractions, we multiply the first fraction by the reciprocal of the second fraction. Thus, this becomes '2 * 7/13' (i.e. '2' over '1' times '7' over '13'). Multiplying the numerators together gives us '14', and multiplying the denominators together gives us '13'. Therefore, '2 divided by 1 6/7', in simplest form, is '14/13' or '1 1/13' when converted to a mixed number.

✓ Express 9 inches of rain in 72 hours as a unit rate. *
The unit rate of 9 inches of rain in 72 hours is calculated by dividing the depth of the rainfall by the duration, resulting in a unit rate of 0.125 inches of rain per hour.
To express 9 inches of rain in 72 hours as a unit rate, you divide the total amount of rain by the total number of hours to find the rainfall intensity per hour. The calculation would go as follows:
Write down the total rainfall depth: 9 inches.
Write down the duration over which the rain occurred: 72 hours.
Divide the total rainfall depth by the duration to calculate the unit rate: 9 inches / 72 hours = 0.125 inches per hour.
So, the unit rate is 0.125 inches of rain per hour.
The population of Australia is approximately 19,500,000. Approximately 195,000 are of the ethnic group called
Aborigines. The Aborigines population is about what percent of the total population?
Answer:
1% of the whole australian population is Aborigines.
Step-by-step explanation:
Do [tex]\frac{part}{whole}[/tex] which is [tex]\frac{195000}{19500000}[/tex] and you get the answer 0.01 which (as a percent) can also be recognized as 1%.
Final answer:
The Aboriginal population forms about 1% of the total population of Australia when using the provided figures of a total population of 19,500,000 and an Aboriginal population of 195,000.
Explanation:
To calculate the percentage of the Aboriginal population in Australia relative to the total population, we can use the following formula:
Percentage = (Part / Whole) × 100
Here the 'Part' is the Aboriginal population and the 'Whole' is the total population of Australia. Plugging in the values provided:
Total Population (Whole) = 19,500,000Aboriginal Population (Part) = 195,000Percentage of Aboriginal population = (195,000 / 19,500,000) × 100
Perform the division:
Percentage = 0.01 × 100
Finally, we multiply by 100 to convert the decimal to a percentage:
Percentage = 1%
Therefore, the Aboriginal population forms about 1% of the total population of Australia. Note that this number might be an underrepresentation since recent estimates indicate that the Aboriginal population is about 450,000, which would be a larger percentage.

Suppose x is an odd number. Write an expression to represent each of the following:
a. The odd number immediately following x. _________
b. The odd number immediately preceding x. _________
Thank You!! =^)
Answer:
a. The odd number immediately following x = ( x+ 2)
b. The odd number immediately preceding x = ( x- 2)
Step-by-step explanation:
Odd Numbers : The number which DO NOT have 2 as their common factor are called odd numbers.
Hence, odd number IS NOT divisible by 2.
Some examples are : 1,3,5,7,9,..........
So, by the given examples, we can see that the difference between any TWO consecutive odd number is ALWAYS 2.
Here, given x : odd number
So, using the above argument :
a. The odd number immediately following x = ( x+ 2)
b. The odd number immediately preceding x = ( x- 2)
Final answer:
a. The expression for the odd number immediately following an odd number x is x + 2.
b. The odd number immediately preceding x is x - 2.
Explanation:
a. If x is an odd number, the next consecutive number is an even number, which is obtained by adding 1 to x. Since odd numbers are two units apart, adding 2 to an odd number x would result in the next odd number. Therefore, the expression to represent the odd number immediately following x would be x + 2.
b. Similarly, the odd number immediately preceding an odd number x can be found by subtracting 2, because the prior odd number is two units less than x. The expression for the odd number immediately preceding x is x - 2.

How much water must be added to 1 liter of a 5% saline solution to get a 2% saline solution?
Answer:
- 1,5 liters
Step-by-step explanation:
If 1 liter has 5% of saline solution, we know that our solution has 2,5 times the salt we want it to have: [tex]\frac{5\%}{2\%} =2.5[/tex], which means that, in the liter of water, there is an amount of salt that is 1,5 greater than what is desired.Then, if we want to lower the concentration of salt, we just have to add water. How much water? 1.5 liters. Then, 5% of solution divided in 2.5 liters of water yields in a 2% solution.Answer:
The water must be added to 1 liter of a 5% saline solution to get a 2% saline solution is 1.5 litres
Explanation:
We assume that the quantity of water added to be x litres. The quantity of saline in the existing solution is 5% of 1litre = 0.05 litres, with the addition of water, the quantity of new solution becomes (1 + x) litres. As per the problem, the percentage of saline in new solution should be equal to 2%. Therefore,
[tex]\frac{0.05}{1+x} \times 100=2[/tex]
So, 5 = 2(1+x)
2x = 5 - 2
[tex]x=\frac{3}{2}=1.5[/tex]
So, 1.5 litres water should be added to make the 1litre 5% saline solution a 2% saline solution.

Which of the following represents the equation of the inverse of y=5x-20
The equation of the inverse of y = 5x - 20 is y = (x + 20)/5.
Explanation:To find the equation of the inverse of y = 5x - 20, we need to switch the x and y variables and solve for y. So the inverse equation will be x = 5y - 20. Now, let's isolate y by adding 20 to both sides: x + 20 = 5y. Next, divide both sides by 5: (x + 20)/5 = y. Therefore, the equation of the inverse is y = (x + 20)/5.
