Answer: x=14 like and plzzzzzzz mark brainlyest
Step-by-step explanation:
1. 7x-6=104
2. 7x -6 = 104
+6 +6
3. 7x= 98
4 7x/7 = 98/7
5. x= 14
The expression is correct because changing the place in the multiplication operation does not affect the final result.
An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,the equation is 1.8 x 3) x 2.1 = 3 x (1.8 x 2.1) t
L.H.S
=(1.8×3)×2.1
=5.4×2.1
=11.34
R.H.S.
=3 x (1.8 x 2.1)
=3×3.78
=11.34
L.H.S.=R.H.S.
Thus, the expression is correct because changing the place in the multiplication operation does not affect the final result.

Answer:
63'020'000 kg or 6.302 × 10^7
Step-by-step explanation:
Freight train = 9.98 • 10^6 = 9'980'000 kg
Aircraft carrier = 7.3 •10^7 =73'000'000 kg
Thus 73000000 kg - 9'980'000 kg = 63'020'000 kilogram =
= 6.302 × 10^7
(scientific notation)
= 6.302e7
(scientific e notation)
= 63.02 × 106
(engineering notation)
(million; prefix mega- (M))
= 63020000
(real number)
