3/5x - 7 =23

What does x equal?
A.) x=40
B.) x=45
C.) x=50
D.) x=55

3x/5-7=23

3x/5=7+23=30

3x/5=30

3x=5×30=150

x=150/3=50

C) x=50

C) x=50

Step-by-step explanation:

3/5x-7=23

3/5x=30

3x=150

x=50

C must be right

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
