Let x = number of miles, cost per mile = 82 cents = $0.82
Cost = 19.95 + 0.82*x
178.21 = 19.95 + 0.82x
0.82x + 19.95 = 178.21
0.82x = 178.21 - 19.95
0.82x = 158.26
x = 158.26/0.82
x = 193
<span>He drove 193 miles. </span>
It is greater than because 74 fl. oz. is equal to 9.25 cups.
Answer:
It means X to the variable of m.
It would look like this:
Answer:
x = 90°
Step-by-step explanation:
Using the identity
cos²x = 1 - sin²x
Given
cos²x - sin x + 1 = 0
1 - sin²x - sin x + 1 = 0
- sin²x - sin x + 2 = 0 ← quadratic equation in sin x ( multiply through by - 1 )
sin²x + sin x - 2 = 0 ← in standard form
(sinx + 2)(sinx - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
sinx + 2 = 0 ⇒ sinx = - 2 ← has no solution as - 1 ≤ x ≤ 1
sinx - 1 = 0 ⇒ sinx = 1 ⇒ x = 90°
solution is x = 90°
Answer:
9√3- ^5√9
you would need to write in exponential form
