a bread recipe calls for 4 eggs for every 1 and a half pounds of flour you use. If you had 12 pounds of flour, how many eggs wou
ld you need to make all the bread that you could?
2 answers:
Firstly, we need to find the number which, when multiplied with 1 1/2, = 12. To do this, we can do 12÷1 1/2 = 8.
Since there is 8 times the amount of flour used, there must be 8 times the amount of eggs used to keep the ingredients in proportion.
4 x 8 = 32
32 eggs would be used to make all the bread possible with 12 pounds of flour.
4 for every 1.5 pounds
We can set up a proportion to solve for x (our needed eggs)
4/1.5 = x/12
Cross multiply
4*12=1.5x
48=1.5x
1.5x/1.5= 48/1.5
1.5 and 1.5 cross out and we are left with x on one side of our equation.
x= 48/1.5
Now we need to divide to solve for x.
48/1.5= 32
x=32
Our final answer is that for 12 pounds of flowers, we need 32 eggs.

Step-by-step explanation:
parallel to the line y = 5x - 3, so the other lines must have same slope m = 5
y - y1 = m(x - x1)
y - 5 = 5(x-2)
y = 5x - 10 + 5
y = 5x - 5
