Answer:
3a = 
Step-by-step explanation:
Given
2a + 4b = 5 ← substitute a = 3b into the equation
2(3b) + 4b = 5
6b + 4b = 5
10b = 5 ( divide both sides by 10 )
b = 
= 
Now
a = 3b = 3 × = 
, thus
3a = 3 × =
Answer:
A.
Step-by-step explanation:
Plugging in all the values into the equation, only A holds a true statement.
60 dollars u divide 720 from 12 and u get 60
Answer:
6x + y = 3
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - 6x + 3 ( add 6x to both sides )
6x + y = 3 ← in standard form
