A restaurant needs four chairs for each table. Let c represent the number of chairs it needs if there are t tables. Which variable is dependent ? Which is independent? Write an equation to represent the relationship, (whoever is the first and has the correct answer gets 100 points and ill give you brainliest. PLEASE I NEED THIS TODAY)

DV = numbers of chairs needed (c)

IV = number of tables (t)

IV × 4 = DV     OR    t × 4 = c

Step-by-step explanation:

DV dependent variable

IV independent variable

brainliest please?

The dependent variable means that it depends on how the independent variable is being manipulated. The independent variable is a variable that represents an amount that is being manipulated.

The dependent variable is "c" because it depends on the number of chairs it needs if there are t tables.

The independent variable is "t" because it manipulates the amount chair there are by the amount of tables there are.

Equation: 4t = c

4t represents the amount of chairs there are for the amount of tables there are. c represents the total amount of chairs.

Best of Luck!

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
