QUESTÃO 10 - Calcule o valor de x:
a) 8.x=40.
b) 6. x = 18
c) 4.x=28.
d) 15.x = 60​

Answer 1

→ Cálculo :

A) 8.x=40

8x = 40

x = 40 ÷ 8

x = 5

B) 6. x = 18

6x = 18

x = 18 ÷ 6

x = 3

C) 4.x=28

4x = 28

x = 28 ÷ 4

x = 7

D) 15.x = 60​

15x = 60

x = 60 ÷ 15

x = 4

Answer 2

olá !!!

$a)\\8.x=40.\\8x=40\\x=40/8\\x=5\\b)\\6. x = 18\\6x=18\\x=18/6\\x=3\\c)\\4.x=28.\\4x=28\\x=28/4\\x=7\\d)\\15.x =60\\15x=60\\x=60/15\\x=4$

espero ter ajudado
