Okay, let's represent the price of a bed sheet with 'b' and a towel with 't':
54b + 50t = 923
38b + 61t = 791.50
Now, if we subtract both sides by 54b (on the first equation), we get this:
50t = 923 - 54b
Divide both sides by 50:
t = 18.46 - 1.08b
Now that we know this, we can move on to the 2nd equation:
38b + 61t = 791.50
Input the variable 't':
38b + 61(18.46 - 1.08b) = 791.5
38b + 1126.06 - 65.88b = 791.5
38b - 65.88b = 791.5 - 1126.06
Simplify:
-27.88b = -334.56
Because both sides are negative, we can turn it into a positive:
27.88b = 334.56
b = 334.56/27.88
b = 12
Now that we know that b = 12, we can easily input it into any equation:
648 + 50t = 923
50t = 275
t = 5.5
One bed sheet costs $12 and one towel costs $5.50
Option C is the answer.
Answer:
y = 30
z = 115
Step-by-step explanation:
z° + 65° = 180°
(Exterior Angles on the same side of transversal)
z° = 180° - 65°
z° = 115°
z = 115
(5y - 85)° + z° = 180°
(Linear pair angles)
(5y - 85)° + 115° = 180°
(5y - 85)° = 180° - 115°
(5y - 85)° = 65°
5y - 85 = 65
5y = 65 + 85
5y = 150
y = 150/5
y = 30
