Lizzie has 12 necklaces without beads. She also has 22 necklaces that have beads on them. How many necklaces does Lizzie have? Write the fact family that can be made from these numbers

Well we know Lizzie has 12 necklaces without beads, and 22 with beads.

Add them: 12 + 22 = 34 necklaces in total.

Fact family:

12 + 22 = 34.

22 + 12 = 34.

34 - 12 = 22

34 - 22 = 12

step-by-step explanation:

the shape,the size and the distance

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
