Erick, tyson, and lane together sold 90 tickets for the school banquet. erick sold 38 tickets, and tyson sold 24 tickets. how many tickets did lane sell? 12 14 19 28

28 is your answer.

Step-by-step explanation:

Let:

Eric = x = 38

Tyson = y = 24

Lane = z

Set the equation:

x + y + z = 90

Plug in the corresponding numbers for the corresponding variables:

(38) + (24) + z = 90

Simplify. Combine like terms.

(38 + 24) + z = 90

62 + z = 90

Isolate the variable z. Note the equal sign, what you do to one side, you do to the other. Subtract 62 from both sides.

z + 62 = 90

z + 62 (-62) = 90 (-62)

z = 90 - 62

z = 28

28 is your answer.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
