Just as an example, three consecutive integers might be 4,5,6.
If x is the least of these (4 in our example), then the other two integers would be x+1, and x+2.
Then the sum of our three integers is x + (x+1) + (x+2).
Addition is commutative so we can switch any two terms, and it is also associative so we can regroup any terms. This lets is rearrange things with all the "x" together and all the numbers together like this:
(x+x+x) + (1+2) OR 3x + 3
According to the problem, the sum is 126, so 3x+3 = 126.
3x = 123
x = 41 (which is the smallest consecutive integer)
Check our answer: 41 + 42 + 43 = 126.
Answer:
<h2>$39</h2>
Step-by-step explanation:
Step one:
He charged $25 and spent $6 on gas on Monday.
then he made 25-6= $19 mowing his neighbor's lawn.
the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).
So he mowed his Grandparents yard for $20.
total money saved for Monday and Tuesday is
19+20= $39
<u>Hence he has $39 for mowing both yards</u>
