Solve
-49 - 28 = -77
Answer:
-77
Step-by-step explanation:
-x^2-4x to [tex]-7^{2}[/tex]- ( 4 × 7)
-7^2 - ( 4 × 7)
-49 - ( 4 × 7)
-49 -28
=

A parking garage charges $2 for the hour and $1 each additional hour. Fran has $9.90 to spend for parking. What is the greatest number of hours Fran can park
Answer:
Frank can park 8.9 hours at the highest
Step-by-step explanation:
Here, we want to know the greatest amount of time that Frank can park given the amount he has to spend on parking.
From the question, we are told that he pays $2 for the hour and an extra $1 per additional hour.
Now, let the number of additional hour he is going to park be x. The bill for the additional hours will be ; $1 * x = $x
By adding this to the initial $2, we have the total $9.90
So, mathematically;
2 + x = 9.90
x = 9.9 -2
x = 7.9 hours
Now, the initial hour he parked is 1 hour + number of incremental hours = 1 + 7.9 = 8.9 hours

I need help with number 5, I understand the rest but with a fraction I get completely thrown off :(
Step-by-step explanation:
0, _, _, 2, 8/3, ...
Write each number as a multiple of 1/3.
0/3, _, _, 6/3, 8/3, ...
The common difference is 8/3 − 6/3 = 2/3. So the other two terms are 2/3 and 4/3.
TOPIC: simultaneous linear equations
p + 2q = 3,
p - 2q = 3
Answer:
p=3 q=0
Step-by-step explanation:
p+2q=3
p-2q=3
p+2q=3
p=3-2q---------eqn i
p-2q=3
3-2q-2q=3
3-4q=3
-4q=3-3
q=0÷-4
q=0
putting the value of q in equation i
p=3-2q
=3-2×0
=3
Answer:
p=3
q=0
Step-by-step explanation:
Adding both the equation
p+2q=3
+ p-2q=3
------------
2p=6
p=3
putting value of p in any of the above equation we will get the value of q.
3+2q=3
2q=0
q=0
