Answer:
the answer is True
Step-by-step explanation:
The factors are 17 and 3.
The given conditions are two factors of the first number, 51 such that their product is 51 and the sum is the second number 20.
let say, the factors are x and y.
therefore, we can write, x.y = 51 ... (1) and x + y = 20 .... (2)
Putting the value of x from equation (2) in equation (1) we get,
(20 - y).y = 51
or, 20y - y² = 51
or, y² - 20y + 51 = 0
or, y = 17, 3
then x = 3,17
Therefore, The factors are 17 and 3.

Answer: 0
Step-by-step explanation: when you add 25+25 it is equal to 50. when you subtract 100 from 50 it gives you -50. when you add 25+25= 50 so you add that -50 and 50 and it gives you zero (im not very good at explaining hope it helped)
Length in feet multiplied by width in feet multiplied by height in feet divided by 27 equals cubic yards needed.
When dealing in inches: convert inches to feet by dividing by 12.
For example: pour a 25 ft. sidewalk 5 ft. wide and four inches deep.
(25’ x 5 ‘ x 0.333’) / 27 = 1.54 cubic yards
Note* we achieved 0.333 ft. by taking four inches and dividing by twelve.
Another example: yardage for an 80 ft. driveway, 24 ft. wide and 5 inches deep.
(80’ x 24’ x 0.416’) / 27 = 29.58 cubic yards
Answer:
3/4 - 5/12 = 4/12 - 5/12 = -1/12
Step-by-step explanation:
Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.
3/4 - 5/12
we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator .
3/4-5/12 = (9 - 5)/12 = 4/12 . This is his first error . 3/4 - 5/12 is equal to 4/12 not 3/12.
Now let us go to the second part which is the answer minus 5/12
4/12 - 5/12 = (4 - 5)/12 = -1/12
The final answer should be -1/12. This is another error that has been detected.
The correct answer combination should be as follows.
3/4 - 5/12 = 4/12 - 5/12 = -1/12
