The sum of two numbers is 12 the difference of the same is -4 formulate a system of equation and find the number
Answer:
The numbers are a= 4 and b= 8.
Step-by-step explanation:
Let the unknowns number be a and b.
assume a>b.
As per the given condition: The sum of two number is 12 and the difference of the same is -4.
from the above conditions we have:
[tex]a+b =12[/tex] ......[1]
[tex]a-b=-4[/tex] ......[2]
Now, adding equations, we will eliminate b leaving an equation in a that we can solve:
⇒ [1]+[2] gives;
[tex](a+b)+(a-b)=12+(-4)[/tex] or
[tex]a+b+a-b=12-4[/tex]
Simplify:
[tex]2a=8[/tex]
Divide by 2 on both sides, we get
[tex]\frac{2a}{2}= \frac{8}{2}[/tex]
Simplify:
a=4
Substitute the value of a= 4 in equation [1] . to solve for b;
[tex]4+b=12[/tex] or
b= 12-4 =8
Therefore, the numbers a and b are 4 and 8
Find a number whose product with six is the same as its sum with 45
1. Make the equation. The product of the number and 6 equals the sum of the number and 45, so the equation would be 6x = x + 45.
2. Subtract x from both sides. You'll get 6x - x = 45.
3. You can combine like-terms by subtracting 6x - x. This is the same as 6x - 1x, which is 5x. You'll get 5x = 45.
4. Divide both sides by 5 to get x = 9.
Therefore, the number is 9.

How many times larger is 3 x 1015 than 6 x 1010?
Final answer:
To find how many times larger 3 x [tex]10^{15}[/tex] is than 6 x [tex]10^{10}[/tex], divide the first by the second resulting in 5 x [tex]10^{4}[/tex]. This means 3 x [tex]10^{15}[/tex] is fifty thousand times larger than 6 x [tex]10^{10}[/tex].
Explanation:
To find out how many times larger 3 x [tex]10^{15}[/tex] is than 6 x [tex]10^{10}[/tex], you can divide the first number by the second number:
Write the division of the two numbers using scientific notation: (3 x [tex]10^{15}[/tex] ) / (6 x [tex]10^{10}[/tex]).Divide the coefficients (3 / 6) which equals 0.5.Simplify the powers of ten by subtracting the exponents ([tex]10^{15} / 10^{10}[/tex] becomes [tex]10^5[/tex]) because when you divide powers of ten, you subtract the exponents.Multiply the results of steps 2 and 3 together - [tex]0.5 * 10^5[/tex].Since 0.5 x 105 is equal to 5 x 104, 3 x [tex]10^{15}[/tex] is 5 x [tex]10^{4}[/tex] times larger than 6 x [tex]10^{10}[/tex].This means that 3 x [tex]10^{15}[/tex] is fifty thousand times larger than 6 x [tex]10^{10}[/tex].

I have attached a photo of the work written for this question:
John played a note on his tuba that vibrated the air 120 times per second. If you play the note for 4 seconds, how many times in the air vibrate?
480
This is this awnser because its 120 a second, for 4 seconds so 4 times 120 = 480.
Well the equation is rate*time=work/distance(in this case total vibrations)
Now we plug in the numbers:
(we know that 120 times per second is the rate because it uses the word per)
(4 seconds is the time because the unit is just seconds)
12*4=48*10=480
120*4=480
The answer is 480 vibrations
Hope this helps :)

Timothy began the week with $35.He bought lunch at school,paying $2.25 for each meal. Let x be the number of meals he bought at school and y be the amount of money he had left for the end of the week. Which equation can represent the relationship in the sitiountaion?
Hello 156339
Since we know the amount of money is always decreasing, then we should know to subtract by 35. Because 2.25 is the cost per meal and x is the number of meals, the total cost should be 2.25x, which is correct because y is the amount of money left over.
Our final equation would be:
y = 35 - 2.25x
:)
The relationship between Timothy's beginning funds, cost of meals, and money left can be represented as y = 35 - 2.25x, where x is the number of meals bought and y is the remaining money.
Explanation:The relationship between the amount of money Timothy started with, the cost of meals he bought, and the money he had left at the end of the week can be represented with a simple linear equation. The key detail provided in your question is that Timothy started with $35 and his meals cost $2.25 each (we can represent the number of meals as x). We can also denote the amount of money he has left at the end of the week as y. We can then write the equation as: y = 35 - 2.25x. With each meal Timothy buys, his remaining money (y) is reduced by $2.25.

Use traditional algorithm to find the quotient 3 ) 137
Using the traditional division algorithm, 137 divided by 3 equals 45 with a remainder of 2.
Explanation:To find the quotient of 3 divided into 137 using the traditional divisor algorithm, we take it step by step. Starting from the left, we see if 3 fits into the first digit, 1. It does not, so we look at the next digit, making it 13. 3 fits into 13 four times. Write this 4 on top of the division line. Then you subtract the value of 4 times 3, or 12, from 13 to get a remainder of 1. Bring down the next digit from the dividend, so now we're dividing 3 into 17. 3 fits into 17, five times. Write this 5 on top of the division line. Therefore, 137 divided by 3 using traditional division algorithm equals 45 remainder 2.

Sonny Siebert earned $485,000 a year as a rookie pitcher for the Cleveland Indians. Assuming a tax rate of 6.2% for Social Security up to $118,500 and Medicare tax of 1.45%, how much did Sonny pay in FICA taxes as a rookie pitcher?
Answer:
14379.50
Step-by-step explanation:
If I remember correctly, the Medicare tax is taken on Gross Income. The question has already limited the base amount for Social Security.
Social Security: 118,500 * 6.2/100 = 7347
Medicare Tax: 485,000*1.45/100 = 7032.50 Add
Add 14379.50
Sonny paid 14370 in taxes for these 2 items.
Answer:
$14,379.50
Step-by-step explanation:
Given that:
Sonny Siebert Income: $485,000Social Security tax rate: 6.2% up to $118,500Medicare tax of 1.45%As we know that, the Federal Insurance Contributions Act (FICA) is made up of two items, Social Security and Medicare taxes.
So
Social Security tax: $118,500*6.2% = $7347
Medicare tax: $485,000*1.45% = $732.5
=> the amount of FICA taxes as a rookie pitcher she needs to pay is:
= $7347 + $732.5
= $14,379.50

What is 2.26 (26 repeating)as a fraction
The repeating decimal 2.26 (with 26 repeating) is converted to a fraction by setting it as 'x', scaling by 100, subtracting the original x, and then simplifying to get the fraction 224/99.
To convert the repeating decimal 2.26 (with 26 repeating) to a fraction, we use the following steps:
Let x = 2.262626..., which is the number we want to express as a fraction.Multiply x by 100 (since the repeating part is two digits long), so 100x = 226.262626....Subtract the original number x from this new number, so 100x - x = 226.262626... - 2.262626..., which gives us 99x = 224.Now, divide both sides by 99 to solve for x. Therefore, x = 224 / 99.We now have our fraction, which is 224/99.

The weekly salaries (in dollars) for

employees of a small business are given below.
(Note that these are already ordered from least to greatest.)
679, 715, 799, 844, 891, 917, 938, 1002, 1027 Suppose that the
$
1027
salary changes to
$
946
. Answer the following.
(a) What happens to the median?
It decreases by
$
.
It increases by
$
.
It stays the same.
(b) What happens to the mean?
It decreases by
$
.
9
It increases by
$
.
It stays the same.
Answer:
a) Median stays the same
b) Mean is decreased by $9
Step-by-step explanation:
The median is the number or the average of the two numbers that is in the middle of a sorted distribution of numbers,
Here the median number will be the 5th number counting from left or right from the sorted list of numbers. Therefor is is 891.
When 1027 is changed to 946 it will fall between 938 and 1002. So updated sorted list of numbers will now look like,
679, 715, 799, 844, 891, 917, 938, 946, 1002
Here also median will be the 5th number which will be equal to 891.
Therefore, , median will not change.
Mean is the value we get by taking the total value of the salaries and divide it by the number of employees.
In the initial case,
Mean =[tex]\frac{679+715+799+844+891+917+938+1002+1027}{9} =868[/tex]
When the salary is changed from $1027 to $946,
Mean=[tex]\frac{679+715+799+844+891+917+938+1002+946}{9} =859[/tex]
Therefor we can see that Mean has decreased by $9.
