The least of 3 consecutive integers is a, and the greatest is z. What is the value of a + 2z/ 2 in terms of a?
jasenka [17]

Answer:

The value of a + 2z/ 2 in terms of a is (3a+4)/2

Step-by-step explanation:

least of 3 consecutive integers is a, and the greatest is z

if a is the least one

we know that integers differ by value of 1.

example -2, -1, 0, 1,2

they all differ by

then next consecutive integer will be a+1

third integer will be  second integer +1 = a+1 + 1 = a+2

Thus, 3 consecutive integer

a , a+1, a+2

but given that greatest is z

thus, a+2 is greatest and hence

a+2 = z

we have to find   value of a + 2z/ 2 in terms of a

a + 2z/ 2 = a + 2(a+2)/2 = (a+ 2a +4)/2 = (3a+4)/2.

The value of a + 2z/ 2 in terms of a is (3a+4)/2

Which of the following equations have exactly one solution?
Tems11 [23]

Answer:

A, B, & C

Step-by-step explanation:

A: -5x +12 = -12x - 12

    +12x        +12x

    7x + 12 = -12

         -12     -12

            7x = -24                 [Divide both sides by 7 to get x]

              x = -24/7

B: −5x + 12 = 5x + 12

   -5x            -5x

    -10x + 12 = 12

            -12     -12

            -10x = 0                   [Divide both sides by -10 to get x]

                 x = 0

C: −5x + 12 = 5x − 5

    -5x           -5x

    -10x + 12 = -5

            -12      -12

           -10x = -17                  [Divide both sides by -10 to get x]

               x = 17 / 10

D: −5x + 12 = −5x − 12

    +5x           +5x

              12 ≠ -12         [The statement is false, so it isn't the correct answer]
