Answer:
It is the first one.
Step-by-step explanation:
Answer:
7(1-8n)=0
We simplify the equation to the form, which is simple to understand
7(1-8n)=0
Reorder the terms in parentheses
+(+7-56n)=0
Remove unnecessary parentheses
+7-56n=0
We move all terms containing n to the left and all other terms to the right.
-56n=0-7
We simplify left and right side of the equation.
-56n=-7
We divide both sides of the equation by -56 to get n.
n=0.125
This question can be solved by:

Cross multiply to get: 8.3x = 3,560,000
To let the x stand along (since you are finding the x value), divide 8.3 to both sides of the equal sign.

Simplify to get the answer.
This is a tricky question for me
They are the same answer. .7 is in the 10th place which is the same as .70 just adding a zero doesn’t change the number
