The answer is B I’m pretty sure
The weekday hours you purchased is 5 hours.
The number of weekend hours I can purchase if the weekday hours tripled is 11 hours.
<h3>What are the linear equations that represent the question?</h3>
2a + 10b = 220 equation 1
a + b = 26 equation 2
Where:
- a = number of hours for weekday parking
- b = number of hours for weekend parking
<h3>How many weekday hours did you purchase?</h3>
Multiply equation 2 by 10
10a + 10b = 260 equation 3
Subtract equation 3 from equation 2
8a = 40
a = 5 hours
<h3>What is the weekend hours I can purchase?</h3>
(5 x 3) + b = 26
15 + b = 26
b = 26 - 15
b = 11 hours

Answer:
yeah I Wii help you to your problem
Hi there!
I'm going to assume you mean m^2 + m - 20.
The factor of this is (m + 5)(m - 4)
And I found this by finding what two numbers add to 1 and multiply to -20, which is 5 and -4.
Now if you FOIL this, (First, outer, inner, last terms) you should come to the initial equation.
(m + 5) * (m-4)
m * m = m^2
5 * m = 5m
m * -4 = -4m
5 * -4 = -20
So, in combining like terms, you'd get m^2 + 1m -20.
