What is the sum of two consecutive integers is less than 83. Find the pair of integers with the greatest sum

1 answer:

7 0

Well, the sum has to be less than 83. Do you think maybe it could be 82 ? ?
Sadly, it couldn't be 82. If two integers are consecutive, then one is even and
one is odd, and their sum is always odd. So the greatest sum less than 83
is going to be 81 .

Since the integers are consecutive, both of them have to be right around
half of 81 . Half of 81 is (40 and 1/2), so let's try 40 and 41 :

40 + 41 = 81  That's it ! yay!

Answer:

7-5 => 2
-7+5 => -2
-7-5 => -12
7-(-5) => 12

Step-by-step explanation:

Lets solve the expressions one by one

1. 7-5

we can see that it is simple subtraction. A smaller number is being subtracted from a large number.

So the answer is 2

2. -7+5

There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.

In this case, 7 is larger and has negative sign, the answer will be -2

3. -7-5

When there are two numbers with minus sign they are added but the answer has the minus sign with it.

So the answer will be: -12

4. 7-(-5)

When minus is multiplied with minus it converts to positive

$= 7-(-5) = 7+5 = 12$

Hence,

7-5 => 2
-7+5 => -2
-7-5 => -12
7-(-5) => 12

Answer:

17/99

Step-by-step explanation:

Replace the digits 23 in your example with the digits 17 and you have your answer:

$0.\overline{17}=\dfrac{17}{99}$

_____

In general, a 2-digit repeat will have 99 as its denominator. If the digits are a multiple of 3 or 11, then the fraction can be reduced. 17 is prime, so the fraction cannot be reduced.

Mark plans on taking 3 trips this summer. He'll drive 143 miles,138 miles , and 141 miles. Estimate the total miles he'll drive.

Deffense [45]

Lets round each distance to the nearest tens place, and then add them up to get an estimate. 143 rounds down to 140, 138 rounds up to 140, and 141 rounds down to 140. So: 140 + 140 + 140 = 420 miles
