Alice, Bob and Carl are jumping up a large flight of stairs. Alice jumps two steps at a time, Bob jumps four steps at a time, while Carl jumps five steps at a time.
on which step will all three land together
for the first time? (Assume they all begin at the foot of the
stairs, i. e. on step 0.)
what is the largest possible number of students in the group!

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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
