Answer:
5400
Step-by-step explanation:
Let x represent the cost of a chair and y represent the cost of a table. We can use this to set up a system of equations:
7x=2y
6x+5y=10575
We can solve this system using substitution.
Start by rewriting the first equation in terms of x.
Substitute this into the second equation:
Multiply both sides by 7
Divide both sides by 47
This means...
Divide both sides by 7
One chair costs 450. Now, multiply this number by 12 to find the cost of 12 chairs.
12 chairs cost 5400.
84/100 which would then be 42/50 which will then be 21/25

Answer:
m = -1/3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Write equation
x + 3y = 10
Step 2: Convert to slope-intercept form
3y = 10 - x
y = 10/3 - x/3
We see that our slope would be the term -1/3x. Since <em>m</em> is the coefficient of <em>x</em> and our slope, our slope <em>m</em> = -1/3
1 gallon = 16 cups
1 quart = 4 cups
1 pint = 2 cups
Therefore...
Multiply
5 gallons × 16 cups = 80 cups
12 quarts × 4 cups = 48 cups
7 pints × 2 cups = 14 cups
Then...
Addition
80 cups + 48 cups + 14 cups = 142 cups
