Answer:
128 servings
Step-by-step explanation:
5/4 cups of milk for 10 servings is equal to 1/8 cup per 1 serving
there are 16 cups in a gallon
let 'n' = # servings in a gallon
so 1/8 : 1 is 16 : n
1/8n = 16
n = 16(8)
n = 128

Answer:
x ≈ 15.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 6² = 17²
x² + 36 = 289 ( subtract 36 from both sides )
x² = 253 ( take the square root of both sides )
x =
≈ 15.9 ( to the nearest tenth )
If Keith is represented by x, and Joe is three less than Keith, Troy is represented by x-3.
Then, we know that Joe exercises for twice the amount of time as Troy, we multiply the expression for Joe by two.
Keith = x
Troy = x-3
Joe = 2(x-3)
