Answer:
B. 90
Step-by-step explanation:
Since the two angles are supplementary, this means they both are on a flat line (180 degrees)
Since both A and B add up to 180, we take that number and subtract A (90) to get our answer: 90 degrees
Answer:
Solutions are x =4 and y = 1
Step-by-step explanation:
In this equation substitute 
, we get
now substitute y =1 in x equation,
Solutions are x =4 and y = 1
Answer:
More than 250 miles
Step-by-step explanation:
Rental cost of company A is $80 + $0.6 per mile driven and company B also has a rental cost of $30 + $0.8 per mile driven.
To find the moment when company A rental cost matches that of company B,we have to create an equation that is ideal for both parties.
80 +0.6x = 30 + 0.8x
Where x is the number of miles traveled by both trucks.
Simplifying the above equation, we have
0.2x = 50 divide both sides by 0.2
= 250 miles is when both rental cost matches .
Therefore, the number of miles needed to be driven so as the rental cost of company A to better company B should be more than 250 miles
If the difference (i.e. subtraction) between the two values is zero, then the answer is yes, they are the same . . .
16:40 = 16 hours and 40 min
12:30 = 12 hours and 30 min
(16h + 40m) - (12h + 30m)
(16h - 12h) + (40m - 30m)
(4h) + (10m)
4h + 10m
4:10 > 0:00 . . . so the answer is no, they are not the same
