Answer:

Step-by-step explanation:

<u>Given:</u>

f(x) =3x - 8 and g(x) = x² + 4
f(g(- 2)) = ?

<u>First find g(- 2):</u>

g(- 2) = (-2)² + 4 = 4 + 4 = 8

<h3>Set up equations</h3>

m - May, j - June

m + j = 84
m = 1/3j

<h3>Solve by substitution, fin the value of j</h3>

1/3j + j = 84
4/3j = 84
j = 84*3/4

Nadya [2.5K]

Answer:

The last guy's height is 69 inches

Step-by-step explanation:

mean=sum of all numbers/number of numbers

There are 5 numbers in the set which means that 65 is the sum of all five numbers divided by 5. To reverse that we multiply 65 by 5 to get the sum of all of the numbers.

$65*5=325$

325 is the sum of all of the numbers so to find the missing number you add up all of the known numbers in the set and find the difference between that sum and 325.

$60+67+65+64=256$

$325-256=69$

The missing guy's height is 69 inches.
