It’s 12/16 which simplify to 3/4
Answer:
{4, 20}
Step-by-step explanation:
x2 − 24x = −80
divide -24 by 2 and square result get 144
x^2 - 24x + 144 = -80 + 144
(x - 12)^2 = 64
x - 12 = root (64)
x = 12 + 8 or x = 12 - 8
x = 20 or 4
Answer:
x = 12
Step-by-step explanation:
Step 1: Define
f(x) = 2x - 7
f(x) = 17
Step 2: Substitute
17 = 2x - 7
Step 3: Solve for <em>x</em>
<u>Add 7 on both sides:</u> 24 = 2x
<u>Divide both sides by 2:</u> 12 = x
Step 4: Check
f(12) = 2(12) - 7
f(12) = 24 - 7
f(12) = 17
You can do a quick division to figure this out:
2 L / (0.21 L/day) = 9.5 days
