We know that if K is between H and J that HK+KJ=HJ therefore by substitution, x-5+5x-12=25
6x-17=25
6x=42
x=7
Hope it helped <span>y = x/5 + 12/5 </span>
Answer:
Step-by-step explanation:
Define number of videos purchased as "n" and number of CD's purchased as "c" then we can equation the total purchases and the costs by:
8 nephews:
n + c = 8
Spent $121.53
14.95*n + 16.88*c = 121.53
Substitute one variable as a function of the other. Preference the simpler equation (n + c = 8)
n = 8 - c
=>
14.95*(8-c) + 16.88c = 121.53
119.60 + 1.93c = 121.53
1.93c = 1.93
c = 1
=>
n = 7
*Check:
14.95*(7) + 16.88*(1) = 121.53
im so sorry if this is wrong :/
Yes it is a rational question
The slope in the equation of a line is the coeffient of x
the equation of a line and a point is
(y-y1)=m(x-x1)
where m is the slope so 3 is the slope
