Answer:
Step-by-step explanation:
2. The value of the number x from the given statement will be 40.
To find:
The value of the number x.
Solution:
Let us consider the number be x
From the given statement,
one fourth of x will be the number 3 in addition to the number 7.
Thus the value x will becomes,
1/4 *x =3 +7
1/4 x=10
x=10*4
x=40
Thus, the value of the number x derived from the given statement will be 40.
3.x-15=51-x
2x=66
x=66/2
x=33
4. We know that:
If 1/2 is subtracted from a number and the difference is multiplied by 4, the result is 5.
Now:
Let the number be 'x'.
According to the question:
When 1/2 is subtracted from x which will give (x - 1/2) and the difference is multiplied with 4[x - 1/2]*4 to give 5.
Now:
[x - 1/2] * 4 = 5
4x - 1/2 * 4 = 5
4x - 2 = 5
4x = 5 + 2
4x = 7
x = 7/4
Therefore:
When 1/2 is subtracted from 7/4 and the difference is multiplied by 4, the result is 5.
