For a^1 it's a itself
For b^3 it's b*b*b
For a^4 it's a*a*a*a
For b^2 it's b*b
The common factors for the variables a

a*b*b is ab^2
3. Multiply the GCF of the numerical part 2
and the GCF of the variable part ab^2. That is 2

Answer:
(-7, -8)
Step-by-step explanation:
To start we have to isolate a variable to get an equation for it.
Let's get an equation for x from the first equation:
x - 2y = 9
x = 2y + 9
Now that we know what x is in terms of y, lets plug it into our second equation:
3(2y + 9) - 5y = 19
6y + 27 - 5y = 19
y + 27 = 19
y = -8
Now that we know what y equals, let's plug it into our first equation and solve for x:
x - 2(-8) = 9
x + 16 = 9
x = -7
Now that we have x and y, we make our ordered pair, in terms of (x, y):
(-7, -8)

Answer:
7 * 10
Step-by-step explanation:
7 buses of 10 people each means 10 people for every of the 7 buses.
10 + 10 + 10 +
10 + 10 + 10 +
10 = 70 or 7 * 10
