You can write 15,409 like this 10000+5000+400+9 and like this fifteen thousand-four hundred nine
So since each car wash equals $7, you round 12 to 10 and $7 * 10 = $70.
Plus, 22 to 20.
So, $70 * 20 = $1400
So the answer is 1,400
Answer:
The sum is 10s^2t-5st^2. With two separate sections, it is a binomial, and since the sum of the powers of the variables is 2+1=3, it has a degree of 3.
1. The simplified expression is 10x+8y-12.
Combine like terms to simplify the expression.
-6x-12+8y+16x
-6x and 16x are both like terms, so those can be combined.
-6x+16x=10x
10x+8y-12
2. The solution to the equation is x=13.
Solve by adding 17 to both sides of the equation.
-4=-17+x
-4+17=-17+17+x
13=x
Answer:
Parallel means they have the same slope so, y=3x-8
