Answer:  \dfrac{\text{171+x}}{\text{2}}

Step-by-step explanation:

We know that the average of any n observations is given by :-

\text{Average}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}

The given observations : x and 171

Sum of observations : x+171

Number of observations : 2

Now, the average of 171 and x is given by :-

\text{Average}=\dfrac{\text{171+x}}{\text{2}}

Hence, the expression represents the average of 171 and x is \dfrac{\text{171+x}}{\text{2}}.

Is there a proportional relationship? A salt water solution for and aquarium calls for 35 parts of salt to 1000 parts of water t
morpeh [17]

Answer:

Yes

Step-by-step explanation:

To check proportionality :

35 α 1000

35 = 1000k

k = constant of proportionality ;

Divide both sides by 1000 to obtain k

35 / 1000 = 1000k / 1000

0.035 = k

For the ratio Given :

Ratio of 7 parts of salt and 200 parts of water

7 : 200

7 / 200

= 0.035

Since,

k = 0.035 ; 7 / 200 = 0.035

Hence, a proportional relationship exists.

11) The sum of four consecutive integers is 290.
n200080 [17]

Answer:

71, 72, 73, 74 . for details, check below

Step-by-step explanation:

a)  Let's assume that among the four consecutive numbers, the first one is x,

so, the four consecutive numbers should be:

  1. x
  2. x+1
  3. x+2
  4. x+3.

According to the question,

(x) + (x + 1) + (x + 2) + (x + 3) = 290

<h2>b)</h2>

(x) + (x + 1) + (x + 2) + (x + 3) = 290

4x + 6 = 290

4x = 284

x = 284÷ 4

x = 71.

So, the numbers are,

71, 72, 73, 74
