Number 3 because it holds the smallest decimal!
Answer: y=2-2x
Step-by-step explanation:
Answer:
y=-3/7x+3
Step-by-step explanation:
A(0;3) B(7;0)
(y-yA)/(yB-yA)= (x-xA)/(xB-xA)
y-3/-3= x/7
7y-21=-3x
She worked as a carpenter for 12 hours and as a blacksmith for 18 hours.
Assuming you mean she earned $20 as a carpenter and $25 as a blacksmith per hour, with a total of 30 hours for $690,
let c represent carpenter hours and b for blacksmith hours.
20c + 25b = 690
c + b = 30
Subtract b from each side so that c = 30 - b
Plug this value into the first equation
20(30 - b) + 25b = 690
600 - 20b + 25b = 690
600 + 5b = 690
5b = 90
b = 18
To find c, plug this value of b into the other equation
c + 18 = 30
c = 12
Answer:
The correct answer is C
Step-by-step explanation:
