The sum of two consecutive integers is -39. List the two numbers from smallest to greatest

Gemiola [76]

Answer:

-20, -19

Step-by-step explanation:

The average of the two numbers is -39/2 = -19.5. The smaller number is 0.5 less than this, -20, and the larger number is 0.5 more than -19.5, so is -19.

_____

Comment on the problem and solution

I find that working consecutive integer problems is often simplified by working with the average value of those integers:

the average of two consecutive odd integers is the even integer between them
the average of two consecutive even integers is the odd integer between them
the average of an odd number of integers of the same type (consecutive, consecutive odd, consecutive even) is the middle one
The average of an even number of consecutive integers is the "half" number between the middle two (as in this problem).

Add. Write your answer in simplest form. 3/8 + 2/5

Vitek1552 [10]

$\frac{3}{8} + \frac{2}{5} = \frac{(3)(5)}{(8)(5)} + \frac{(2)(8)}{(5)(8)}$
= $\frac{15}{40} + \frac{16}{40}$
= $\frac{31}{40}$

A van travels 168 miles on 14 gallons of gas,At this rate,how many gallons will it need to travel 252 miles?

Artyom0805 [142]

Answer:

The answer would be A.) 21 gallons.

Step-by-step explanation:

1.) The first thing you need to do is see how many miles per gallon the van is using by doing 168/14= 12.

2.) Then, you would apply this to the amount need to travel by doing 252/12= 21, meaning the answer is in fact A.) 21 gallons.

Please help me with this

Answer:

Step-by-step explanation:

Let:

s - side of the square

d - diameter of the circle

r - radius of a circle

C - circumeference of the circle

AC - area of the circle

AS - area of a square

The formula of a perimeter of a square:

P = 4s

We have P = 40cm.

Substitute:

4s = 40 divide both sides by 4

s = 10 cm

The length of the diameter of the circle inscribed in the square is equal to the length of the side of the square.

Therefore d = s → d = 10 cm.

The length of the circle diameter is two lengths of the circle radius.

Therefore d = 2r → r = d : 2 → r = 10 : 2 = 5 cm.

The formula of a circumference of a circle:

C = dπ.

Substitute d = 10cm, and π = 3.14.

C = 10(3.14) = 31.4 cm.

The formula of an area of a circle:

AC = πr²

Substitute r = 5cm and π = 3.14

AC = 3.14(5²) = 3.14(25) = 78.5 cm².

The formula of an area of a square:

AS = s²

Substitute s = 10 cm

AS = 10² = 100 cm²
