So, let's make these two values improper fractions so they're easier to work with. 4+\frac{1}{3}=\frac{12}{3}+\frac{1}{3}=\frac{13}{3} 3+\frac{1}{2}=\frac{6}{2}+\frac{1}{2}=\frac{7}{2}

So, to get the rate he grew in those months we have:

\frac{\frac{13}{3} \text{inches}}{\frac{7}{2}\text{months}} =\frac{26\text{inches}}{21\text{months}}

And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:

\frac{\frac{26}{21} \text{inches}}{\text{month}}\approx \frac{1.24\text{inches}}{\text{month}} aka he grew 1.24 inches in a month.

the sum of three consecutive odd integers is equal to 15 more than twice the middle integer what are the three integers
Naily [24]
Odd integers are 2 apart

the 3 consecutive odd numbers are x,x+2, x+4

sum is x+x+2+x+4 or 3x+6

the sum is 15 more than 2 times middle one
3x+6=15+2(x+2)
3x+6=15+2x+4
3x+6=19+2x
minus 2x both side
x+6=19
minus 6 both sides
x=13

x+2=15
x+4=17

they are 13,15,17

Between what two consecutive integers is <img src="https://tex.z-dn.net/?f=%5Csqrt182" id="TexFormula1" title="\sqrt182" alt="\s
Elden [556K]

Answer:

C. 13 and 14

Step-by-step explanation:

They notice that the square root of 182 is between 13 an 14, and it gives them the idea that the numbers 13 and 14 are the solution.

Let n be the smaller of the two consecutive integers.

   Then the other integer is  (n+1).

   We are given that  

      n*(n+1) = 182.

   Simplify

      n^2 + n - 182 = 0,

   Factor left side

      (n-13)*(n+14) = 0.

   The solutions are  n= 13  and  n= -14.

   You may check that both of them satisfy the problem' condition, giving you two answers

       the pair  (13,14)  and the pair  (-14,-13).

 

Many people prefer to solve this problem in a short way.

   They notice that the square root of 182 is between 13 an 14,

   and it gives them the idea that the numbers 13 and 14 are the solution.

   Then these people get the next idea that if the product of 13 and 14 is equal to 182,

   then the product of the opposite numbers is also 182, so

           both the pairs (13,14)  and  (-14,-13)  are solutions.

Solved and explained in detailed and short modes.
