2. find the smaller of 2 consecutive integers, x, if the sum of the smaller and the rest largeris-5.
Question:
largeris-5. write an equation and some.
Answers
- The smaller integer is -5.
Explanation:-
Let the first consecutive integer be x and the second consecutive integer be x+1.
According to the given question:-
x+6(x+1)= -29
⇒x+6x+6= -29 [distributive law]
⇒x+6x= -29-6 [subtract 6 on the both sides]
⇒7x= -35 [combining like terms ]
⇒x= -5 [dividing 7 on both sides]
Thus the smaller integer =x= -5
larger integer =x+1= -5+1= -4
The correct answer is -5.
Step-by-step explanation:
To start, we use x for the smaller integer. Then we can use that to write the equation as,
x + 6(x + 1) = -29
Now we solve for x.
x + 6x + 6 = -29
7x + 6 = -29
7x = -35
x = -5
Therefore the smaller of the two would be -5
You have defined x to be the smaller of two consecutive integers. Then the larger will be (x+1). The given relation is
... (x) + 3(x+1) = -5 . . . . the smaller plus 3 times the larger is -5
... 4x + 3 = -5 . . . . . . . .simplify
... 4x = -8 . . . . . . . . . . subtract 3
... x = -2 . . . . . . . . . . . divide by the coefficient of x
The smaller of the two integers is -2.
