Answer:
The number is 24
Step-by-step explanation:
Let x and y be the 2 digits .
Note that because x and y are integers and the original number is a multiple of 3 and 4, it must also be a multiple of 12.
So by trial and error:-
Let the number be 12:-
x + y = 3 and 4 * 3 = 12 so this fits the first condition.
x * y = 2 and 3 * 2 = 6 . This does not fit.
Let the number be 24:-
xy =24 , x + y = 6 and 4*6 = 24 . This fits.
x*y = 8 and x*y = 24 This fits.
The answer is 24
Lets make this unknown number named X
74-32=x-30
42=x-30
x=72
74-32=72-30
Answer:
Answer is (a)
Step-by-step explanation:
Well I didn’t really do any work but you can tell right away theres a ton of slope options so you can’t eliminate from there, BUT when you look at the y-intercept, 3 is the only y-intercept option here and the only choice with the y-intercept of 3 is (a).
Hoi!
To solve this, first plug in the values for x and y.
![4x + \frac{1}{2}y](https://tex.z-dn.net/?f=4x%20%2B%20%5Cfrac%7B1%7D%7B2%7Dy%20)
Turns into...
![4(2) + \frac{1}{2}(3)](https://tex.z-dn.net/?f=4%282%29%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%283%29)
Now that we've got the values plugged in, let's solve.
4 × 2 = 8
![8 + \frac{1}{2}(3)](https://tex.z-dn.net/?f=8%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%283%29)
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
× 3 =
![1 \frac{1}{2}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B1%7D%7B2%7D%20)
![8 + 1 \frac{1}{2} = 9 \frac{1}{2}](https://tex.z-dn.net/?f=8%20%2B%201%20%5Cfrac%7B1%7D%7B2%7D%20%3D%209%20%5Cfrac%7B1%7D%7B2%7D%20)
is your answer. :)
