Answer:
yes this is true
Step-by-step explanation:
this is because 2x3=6 so 2x3g=6g
Let x = the unknown number.
Because three-sevenths of the number is 21, therefore
(3/7)x = 21
That is
(3x)/7 = 21
Multiply each side by 7.
3x = 21*7 = 147
Divide each side by 3.
x = 147/3 = 49
Answer: 49
Answer:
x=-5
Step-by-step explanation:
7x+35=0
subtract 35 from both sides
7x=-35
divide both sides by 7
x=-5
