The sum of two numbers is 47 and the difference is 19. What are the numbers?
Answer: The two numbers are 33 and 14
Step-by-step explanation: We shall start by first assigning letters to unknown variables. Therefore let the two numbers be called a and b. The first clue in this question states that the sum of both a and b equals 47. That means we can write the expression;
a + b = 47.
The second clue states that their difference equals 19. This also can be expressed as follows;
a - b = 19
Now we have a pair of simultaneous equations which are
a + b = 47 ———(1)
a - b = 19 ———-(2)
We shall use the substitution method. Therefore from equation (1), make a the subject of the equation.
a = 47 - b
Next we substitute for the value of a in equation (2)
a - b = 19
47 - b - b = 19
47 -2b = 19
By collecting like terms we now have 47 - 19 = 2b
28 = 2b
Divide both sides of the equation by 2
14 = b
We can now substitute for the value of b into equation (1)
a + b = 47
a + 14 = 47
Subtract 14 from both sides of the equation
a = 33.
Therefore the two numbers are 33 and 14.
The two numbers with a sum of 47 and a difference of 19 are 33 and 14. We found this by setting up two equations based on the given information and solving for the two variables.
Explanation:The sum of two numbers is 47 and the difference is 19. To find these two numbers, we can set up a system of equations and solve them. Let the numbers be x and y.
x + y = 47 (equation 1)x - y = 19 (equation 2)Adding both equations, we get 2x = 66, hence x = 33.
Substituting x in equation 1, we get 33 + y = 47, hence y = 47 - 33 = 14.
Therefore, the two numbers are 33 and 14.

Missing fraction
blank + 1/16 = 3/2
Final answer:
To solve for the missing fraction in the equation blank + 1/16 = 3/2, convert 3/2 to a fraction with a denominator of 16 to give 24/16. Then, subtract 1/16 from 24/16 to get the missing fraction, which is 23/16.
Explanation:
To find the missing fraction in the equation blank + 1/16 = 3/2, we first need to express 3/2 with the same denominator as 1/16 to facilitate addition. The common denominator for 16 and 2 is 16, so we can rewrite 3/2 as 24/16 (since 3 × 8 = 24 and 2 × 8 = 16). Our equation now is blank + 1/16 = 24/16. To solve for the missing fraction (blank), we subtract 1/16 from 24/16, which gives us 23/16.
Example:
Rewrite 3/2 as 24/16
Subtract 1/16 from 24/16 to find the missing number
The missing fraction is 23/16
This method demonstrates how to find a missing fraction by creating a common denominator and then subtracting to isolate the missing number.

8 g + 10 = 35 + 3 g
Answer:
g = 5
Step-by-step explanation:
8 g + 10 = 35 + 3 g
in order to get the value of g, firt of all rearrange the expression or in ither words collect the like terms.
8 g + 10 = 35 + 3 g
8g + 10 - 3g = 35
NOTE; when you are moving a number with positive sign across the equal to = sign the positive changes to negative and same thing applies to the negative sign it changes to positive sign.
we have;
8g -3g = 35 - 10
5g = 25
divide both sides by 5
5g/5 = 25/5
g = 5
Eric needs to order programs for the next school football game. Only 1 out of 2 people will buy a program for the game. If there will be 900 people at the game and programs come in boxes of 50, how many boxes of programs should Eric order?
Answer:
Eric should order 9 boxes of programs.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Probability of buying a program for the game = 1/2
Number of people at the game = 900
Number of programs per box = 50
2. How many boxes of programs should Eric order?
Let's calculate the answer this way:
Number of programs required for the next football game = Probability of buying a program for the game * Number of people at the game
Replacing with the values given, we have:
Number of programs required for the next football game = 1/2 * 900
Number of programs required for the next football game = 450
Now, we can calculate he number of boxes, this way:
Number of boxes of programs Eric should order = Number of programs required for the next football game /Number of programs per box
Replacing with the values given, we have:
Number of boxes of programs Eric should order = 450/50
Number of boxes of programs Eric should order = 9

ok so first you need to divide 144 by 12 = 12
then you need to figure if you split that in half it equals 6.
now we know that for every 12 miles you drive, you need 1 gallon of gas
now you need to divide 240 by 6 = 40
so you will need 40 gallons of gas to drive that far
we are not one yet, then you need to take away 6 from 40 witch comes to 34.
