The sum of four consecutive integers is 418. Find them.
cupoosta [38]

Answer: 103, 104, 105, and 106

Step-by-step explanation: This problem states that the sum of 4 consecutive integers is 418 and it asks us to find the integers.

First represent your 4 consecutive integers as follows.

X ⇒ first integer

X + 1 ⇒ second integer

X + 2 ⇒ third integer

X + 3 ⇒ fourth integer

Since their sum is 418, our equation reads

x + (x + 1) + (x + 2) + (x + 3) = 418.

Simplifying on the left side we get 4x + 6 = 418.

Now we can subtract 6 from both sides of the equation and we have

4x = 412.

Now just divide both sides by 4 and we find that <em>x = 103</em>.

Finally, make sure you list all your answers.

If <em>x</em> is 103, then <em>x </em>+ 1 is 104, <em>x</em> + 2 is 105, and <em>x</em> + 3 is 106

Therefore, our 3 consecutive integers are 103, 104, 105, and 106.

Suppose a - b = 0a−b=0a, minus, b, equals, 0. Which one of these expressions equals a+ba+ba, plus, b?
Lelu [443]
First we have the following equation:
 a - b = 0
 We clear one of the variables depending on the other:
 a = b
 Therefore we have to for the following expression:
 a + b
 We can substitute one of the variables, obtaining:
 a + a = 2a
 Equivalently:
 b + b = 2b
 Answer:
 
a + b = 2a
 
or
 
a + b = 2b

A number cube is rolled.
Diano4ka-milaya [45]

Answer:

Since there are 6 sides to a cube, the probability of rolling anything but 5 is five out of six.

Fraction is 5/6

To find the decimal, divide 5 by 6 and round to the nearest hundredth

Decimal is 0.83

Then to find the percent you slide the decimal over two spaces.

Percent is 83%

The ratio is 5:6\
