Draw a quick picture to show the number 24 then draw a quick picture to show 24 after you have regrouped 1 ten as 10 ones explain how both pictures show the same number 24

Step-by-step explanation:

Total pink triangles = 24

Let first 10 triangles be a circle

let second ten triangles be a square

⇒ red circle = 10 triangles

⇒blue square = 10 triangles

Remaining triangles = 4

Thus circle+square+4 triangles=10+10+4

                                                   =24

Refer the attached figure.

This is a quick picture to show 24 after you have regrouped 1 ten as 10 ones

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
