The answer would be A. <span>The registration fee is $5.50, and the cost per download is $0.95.</span>
Solution
Let x = registration fee
y = cost/downloads
Jack
15y + x = 19.75 ; x = 19.75 - 15y
Jim
40y + x = 43.50
Thus,
40y + x = 43.50
40y + <span>19.75 - 15y = 43.50
</span>25y = 23.75
y= 0.95
for x,
<span>x = 19.75 - 15y</span>
x = 19.75 - 15( 0.95)
x= 19.75 -14.25
x = 5.5
Answer:
the number is 31.2
Step-by-step explanation:
Given that:
1/2x-19.7=-4.1
Adding 19.7 on both sides:
1/2x-19.7 + 19.7=-4.1 + 19.7
1/2x = 15.6
Multiplying both sides by 2:
x = 15.6 * 2
x = 31.2
So the number is 31.2
i hope it will help you!
Let the number be x and 2x-5 from the above given condition
x+2x-5=70
or
3x=75 s0 x=25
Hence, the number are 25 and 45
U use y=mx+b to find the slope, and the answer would be m=-3
