Three times the sum of half Carlita’s age and 3 is at least 12. What values represent Carlita’s possible age?

c >= 2

Step-by-step explanation:

Step 1: represent the question with an equation

Let the missing age be c

3 times 1/2c + 3 is greater than or equal to 12

3 (1/2c +3) >= 12

Divide both sides by 3

1/2c +3 >= 4

Combine like terms

1/2c >= 4 -3

1/2c >= 1

Divide both sides by 1/2

c >= 1 ÷ 1/2

c >= 1 x 2/1

c >= 2

therefore the value that can represent carlita's age starts from 2

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
