Y = base pay + (variable pay * x)
37.50 = base pay + (variable pay * 5)
75 = base pay + (variable pay * 20)
let v be the variable pay:
base pay = y - variable pay * x
37.50 - 5v = 75 - 20v
-5v + 20v = 75 - 37.50
15v = 37.50
v = 37.50/15
v = 2.5
37.50 - 5(2.5) = 75 - 20(2.5)
37.50 - 12.50 = 75 - 50
25 = 25
base pay is 25 ; variable pay is 2.50 per newspaper delivered.
y = 25 + 2.50x
Answer:
Darius took (17-2)^2 instead of 17-2^2, ignoring the order of operations. The answer is 13.
Step-by-step explanation:
To solve 17-2^2, Darius should first square two, then subtract that from 17. By subtracting 2 from 17 first, you ignore the PEMDAS rule (parenthesis, exponents, multiplication/division, addition/subtraction).
2^2=2
17-4=13
133 112
---- = -------
x 16
112x = 133 . 16
112x = 2128
x = 2128/112
x = 19
answer: x = 19

Answer:
Step-by-step explanation:
Let x be the normal time it takes for her to commute. We know that if she was 30min late, this would had 30 min to the journey. She takes a different route, she can travel four times faster than the normal route.
Therefore the normal time of commute will be 4 times less:
This equation states that the commute time will be four times faster and adding the 30min that she is late.
