$a * 10^{b}$ -------->(equation 1)

Let, $a^{'} = 0.0765$

In standard form

$a = 7.65$

As decimal point move 2 places from left to right, therefore

b = -2

Which of the following equations is equivalent to 7y+6=36, but written only in terms of x?

hodyreva [135]

Answer:

14x + 7 = 30

Step-by-step explanation:

Given

7y + 6 = 36 and y = 2x + 1

substitute y = 2x + 1 into 7y + 6 = 36 , that is

7(2x + 1) + 6 = 36 ( subtract 6 from both sides )

7(2x + 1) = 30 ← distribute parenthesis on left side by 7

14x + 7 = 30
