Amovie theater sold adult and student tickets. they sold a total of 200 tickets. the theater sold 28 more adult tickets than student tickets. how many adult and how many student tickets were sold?

Adult = 114

Students = 86

Step-by-step explanation:

If 200 tickets were sold between students and adults (A + S = 200) and 28 tickets were sold more for adults than for students (A = S + 28), then ;

A+S=200 ; A=S+28 →

(S+28)+S=200 → 2S+28=200 → 2S=200-28 → S=172/2 =86

Replacing S in A

A=86+28 = 114

Adult=114

Student=86

Step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
