An athlete runs 3.2 miles a day. How long would it take for an athlete to run 24 miles?

3.2x=24

x=24*3.2

x=7.5

Step-by-step explanation:

answer:

your answer is: c. 196 7/8 in^3.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
