If you divide a number into 3 equal groups and then divide each group in half, you end up with 13. write an equation to express the situation. then, determine what number you started with?

x  = 26

Step-by-step explanation:

Let   x  b the number

then x/3   (we divide x in three equal gups)

And then each group is divide in half

You end up in 13  s we have

x/3  +  X/3/2   =  13

x /3   +  x/6    = 13

(2x  + x  )/6     = 13

2x  +  x   = 78

3x   = 78

x  = 78/3

x  = 26

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
