7hours
Step-by-step explanation:
42hours/6=7hours
So, there are two equations.
5a + 3c = 30
a + c = 8, therefore, a = 8 - c
5a + 3c = 30
5(8 - c) + 3c = 30
40 - 5c + 3c = 30
-2c = -10
c = 5 , So a = 3
Answer:
y = -2x + 150
Step-by-step explanation:
y2 - y1 / x2 - x1
120 - 100 / 15 - 25
20 / -10
= -2
y = -2x + b
100 = -2(25) + b
100 = -50 + b
150 = b
