3. Write 83 .573 in the expanded form.
4. simplify: 36 ÷3+4×3-4 .
5. Simplify using distributive property : 281 × 105 .​

Answer 1

Answer:

I'll try my best !

Step-by-step explanation:

1. 8 : X = X : 2

X² = 8×2

X² = 16

X = 8

2. 5-X / 8-X = 9/6

30 - 6X = 72 - 9X

3X = 52

X = 52/3

4. 36÷3+4×3-4

= 12 + 4 × -1

= -16
