Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 befo

babunello [35]

Answer:

$35

Step-by-step explanation:

first we need to find the amount of money the sweaters cost alone.

so we first subtract the total (160) - the skirt price (20) which is 140

now we divide it by 4 to find the price of each seater, as they all cost the same.

so 140 divided by 4 = 35

2 of 5 What is the nth term rule of the linear sequence below? -9,-5, -1,3,7,... Tn=

icang [17]

Answer:

$T_{n}$ = 4n - 13

Step-by-step explanation:

There is a common difference d between consecutive terms , that is

d = - 5 - (- 9) = - 1 - (- 5) = 3 - 1 = 7 - 3 = 4

This indicates the sequence is arithmetic with n th term

$T_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 9 and d = 4, thus

$T_{n}$ = - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
