Answer:
2x is your slope and -8 is your y intercept
Step-by-step explanation:
I have to form a couple of equations in order to solve it.
let the amount of soybean in the mixture be x and that of cornmeal be y
Step-by-step explanation:
x+y = 280
y = 280 - x
x*(14/100) + y*(7/100) = 280*(12/100)
Multiplying the whole equation by 100;
14x + 7y = 3360
in this equation,put y = 280 - x
14x +7 (280-x) = 3360
14x +1960 - 7x = 3360
14x - 7x = 3360 - 1960
7x = 1400
x = 200lbs
y = 280 - x
= 280 - 200
= 80 lbs
Inorder to make a 280lbs mixture having 12% protein, we should mix 200lbs of soyabean and 80 lbs of cornmeal
Step-by-step explanation:
1: Solve one Equation for one of the variables
2: Substitute (plug-in) this expression into the other equation and solve
3: Resubtitue the value into the original equation to find the corresponding variable
I am not 100% sure but I think the answer is C I hope I helped you and Good luck
Answer:
3. w=P/2-L
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for w:</u>
- P=2(l + w)
- P/2 = 2(l + w)/2
- P/2 = l + w
- P/2 - l = l + w - l
- P/2 - l = w
- w = P/2 - l
<u>Correct answer choice is:</u>
