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
Answer:
7:8
Step-by-step explanation:
150-80=70
80= women
70=men
divide both by 10
8/7
out into a ratio of men to women.
7:8
To make an equation of a line, you must put it in Y=mx +b form.
m = slope and b = y-intercept
Now just plug in
Answer is Y= -4/5x - 1/6
Answer:
5050 and 100 pairs
Step-by-step explanation:
The X-intercept is a point where the line crosses the X lines. That means it would be the point where Y=0. Then to find the X-intercept you only need to insert Y=0 into the equation. The calculation would be:
<span> 4×+2y=12
4X+ 2 (0)= 12
4X =12
X=12/4 = 3</span>
