You can figure this out by setting up an equation and make
x= tens digit
y= ones digit
y + 8 =x (tens digit 8 more than ones)
also we know that
y>0
x>0
since the 10s digit and 1s digit cannot be more than one number, we can say
0 < y > 10
0 < x > 10
since x has to be greater than 0 but less than 10, there is only one number that would fit into the equation for y
2 + 8 = 10
(y cannot equal 2 because than x is equal to 10 and it must be less than)
1 + 8 = 9
( y can be 1 since x is less than 10)
so it would be
y= 1
x= 9
the number would be 91
hope this helped!
Just use syblol it is verygood for varible form
Step-by-step explanation:
n(s)=28
n(p)=14
p(p)= n(p)/n(s)
= 14/28
=1/7

Answer:
x =30
Step-by-step explanation:
in order to evaluate the solution 4/5=20/(x-5)?
solution
the first step to take is to cross multiply
4/5=20/(x-5)
we have,
5 x 20 = 4 ( x -5)
100 = 4x - 20
combine the like terms
100+20 = 4x
120 = 4x
divide both sides by the coefficient of x
120/4 = 4x/4
30 = x
x =30
therefore the value of x in the expression 4/5=20/(x-5)? is 30
