Mathematics

part A-

3t + .80m = 18 (t - tickets) (m - meals)

we already know m = 15 so our equation would turn into

3t + .80(15) = 18

3t + 12 = 18


part B-

3t + 12 = 18

subtract 12 from both sides

3t + 12 = 18

-12 -12

then, 3t= 6

and, we know 3 goes into 6 two times meaning t=2


part C- Erica purchased 2 movie tickets last month

15 meals x $0.80 = $12.
$18 - $12 = $6.

If one movie ticket is $3 then she must have purchased 2 with $6.

Part A - 15x0.8=18-x=x

Part B-
15 x 0.8 = 12
18- 12=6

Part C- 2

What is the explicit formula for this sequence?<br> -7, -3, 1, 5, ...
alukav5142 [94]

Answer:

Step-by-step explanation:

a1 = - 7

d = 4

an = a1 + (n - 1) * d

an = - 7 + (n - 1) * 4

an = - 7 + 4n - 4

an = -11 + 4n

Try this out. Let n = 3

a3 = -11 + 4*3

a3 = - 11 + 12

a3 = 1   Which is what the series says.
