A) tomatoes : chicken broth = 9:15 or 3:5
Tomatoes : spinach = 9:9 = 1:1
Spinach : chicken broth = 9:15 = 3:5
b) tomatoes : chicken broth = 4.5:7.5 = still 3:5
Tomatoes to spinach is still 1:1
Spinach : chicken broth 4.5:7.5 still = 3:5
Dividing all quantities by 2 doesn’t change the ratio.
1/4x + 5/3x - 4 = 2 - 1/12x
Simplify.
Multiply 1/4x by 3/3, as well as multiplying 5/3x with 4/4.
1/4x × 3/3 = 3/12x
5/3x × 4/4 = 20/12x
So, our new question looks like this :
3/12x + 20/12x - 4 = 2 - 1/12x
Simplify.
23/12x - 4 = 2 - 1/12x
dd 4 to both sides, as well as adding 1/12x to both sides.
23/12x + 1/12x = 2 + 4
Simplify.
24/12x = 6
Simplify.
2x = 6
Divide both sides by 2.
x = 3

His rate = d/t because d=rt
So r = 5/2 = 2.5 mi/hr
So d = 5/2•t
