Multply both sides of the equation by 7.
_____
When the variable is in the numerator of a proportion like this, you can solve it by multiplying by that denominator. That multiplication cancels the denominator and gives you the value of the variable.
In general, you multiply by the reciprocal of the coefficient of x. When that coefficient is 1/7, you multiply by 7/1. Of course, you know that 7/7 = 1 and that x/1 = x.
No because the hundred place doesn't move.
1/3x=20
1st step do the opposite of 1/3x to get it by itself. So you would do 1/3x *3/1 than you would do 3/1 *20. What you do to that side you do to the other.
2nd step 20*3=60
3rd You can check your answer by doing 1/3 *60=20
I plugged the answer in the variable to Check it
Your answer is
Rad. 6 + Rad. 2
- (Negative) _______________
4
No
Arithmetic sequence has terms which decrease or increase by the same amount
for example 3,6,8,12 ....
this sequence is geometric where the terms are obtained by multiplying previous term by 10
