Find the sum

20° 15' 18"
30° 41' 32"
+ 2° 30' 15"

( )° ( )' ( )"

53 degrees 27' 5".

Step-by-step explanation:

Adding the seconds we get 65" = 1' 5" ( 5" carry 1')

Adding the minutes gives 1' + 86' = 1 degree 27' (27' carry 1 degree)

Adding the degrees we get 1 + 52 = 53 degrees.

he spend 5.1 minutes chatting with his friends

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
