Five numbers have a range of 14. Four of the numbers are 20, 22, 31 and 25. Work out the two different possible values for the f

Pepsi [2]

Answer:

Step-by-step explanation:

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

the missing number can either by the highest value or the lowest value. this is because none of the numbers given when subtracted from each other would give a value of 14

let x = missing number

14 = x - 20

x = 20 + 14 = 34

14 = 31 - x

x = 31 - 14

x = 17

Answer:

1, 5, 17, 53, 161

Step-by-step explanation:

Given:

$a_1=1$

$a_n=3a_{n-1}+2$

First five terms of the sequence:

$a_1=1$

$a_2=3a_1+2=3(1)+2=5$

$a_3=3a_2+2=3(5)+2=17$

$a_4=3a_3+2=3(17)+2=53$

$a_5=3a_4+2=3(53)+2=161$

The model below represents the equation 3x+2=2x-5,

Leno4ka [110]

Step-by-step explanation:

Hey there!

The equation is;

$3x + 2 = 2x - 5$

Shifting "2x" to left side and "2" to right side.

$3x - 2x = - 5 - 2$

Simplify them to get answer.

$x = - 7$

Therefore the value of x is -7.

Check;

3 × -7 + 2 = 2 × -7 -5

-19 = -19 ( True ).

So, your answer is option B.

Hope it helps..
