437/19=23
23 miles on 1 gallon of gas.
Answer:
870
Step-by-step explanation:
Assuming you mean
30
Using the definition
n =
where n! = n(n - 1)(n - 2) ..... 3 × 2 × 1
Then
30 = =
Cancel the terms 28(27)... on numerator/ denominator, leaving
30 = 30 × 29 = 870
X - y = 5
x = y + 5
y = x - 5
Answer:
3.
Step-by-step explanation:
3x + 6(2x – 2)
We can obtain the factor in the above equation as follow:
3x + 6(2x – 2)
Clear the bracket
3x + 12x – 12
15x – 12
Factorise
3(5x – 4)
From the above illustration, we can see that the factor of the equation
3x + 6(2x – 2) is 3.
