Answer:
$160.75
Step-by-step explanation:
Step one:
given data
The resort charges $20.75 per hour in addition to a $35 deposit to rent a snowboard
The time spent from 8:30 am to 12:30 pm = 4hours
Step two:
Let the number of hours be and the total cost be y
Now the expression for the situation can be represented as
y= 20.75+35x
for x= 4
y=20.75+35(4)
y=20.75+140
y=160.75
Answer:
if the - after simplify is involved it would be 10, 9 and if it's not it's -9, -10.
Answer:
4.
Once 
is opposite to 
, they are the same. It is the same for 
, equals to 40º.
m∠y = 40º
The ∠x and 40º are supplementary, therefore ∠x = 140º.
∠z = 140º
m∠x = 140º
m∠y = 40º
m∠z = 140º
5.
Considering the explanation from the question 4:
m∠x = 50º
m∠y = 130º
m∠z = 50º
