Answer:
Answer is 5
Step-by-step explanation:
Do 175 divided by 35 which is 5.
The equation:
p x + q = 46 x + 23
p x - 46 x = 23 - q
x ( p - 46 ) = 23 - q
x = ( 23 - q ) / ( p - 46 )
This equation has infinitely many solutions for :
23 - q = 0 and p - 46 = 0
or: q = 23 and p = 46
Answer : A ) p = 46 & q = 23
Set up the porportion: x/120= 40/100
Cross multiply: 100x=120 times 40
Answer:
y=2x+4
Step-by-step explanation:
Answer:
x+3*1/x=52/7
7x^2/7x+21/7x=52x/7x
7x^2-52x+21=0
I solve this with the quadratic formula
Solution of ax^2+bx+c=0, a≠0 are :
x1= 
and x2= 
so a=7, b=-52,c=21
x1=
= (52+46)/14=98/14=7
x2=(52-46)/14=6/14=3/7
