Answer:
$3450
Step-by-step explanation:
The cost of one computer is the sum of the cost of the parts:
$120 +100 +45 +30 +50 = $345
Then the cost of 10 of them is ...
10 × $345 = $3450 . . . . cost for 10 computers
Answer:
66
Step-by-step explanation:
Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.
So angle 2 is 57.
Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:
57+57+angle 1=180
114+ angle 1=180
angle 1= 66
4 is your answer have a great day
I think its -1 i not very smart so it probably wrong
