Answer:
10pens
Step-by-step explanation:
23-3=20
20÷2=10
<h3>
Answer: Choice B. x = 4 and x = 3</h3>
Work Shown:
x^2 - 7x = -12
x^2 - 7x + 12 = 0
(x - 3)(x - 4) = 0 ... see note below
x - 3 = 0 or x - 4 = 0
x = 3 or x = 4
Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.
Answer:
200 miles
Step-by-step explanation:
80 = 40% of the trip
Divide 40% and 80 by 10
40% / 10 = 4
80 / 10 = 8
8 = 4% of the trip
100 / 4 = 25
8 x 25 = 200
The trip is 200 miles.
