Answer:
answer is 90
Explanation:
Here 5 is one of the 4 prime factors, so dividing the lower (80) and upper limit (100) by 5 we have new lower limit 16 and new upper limit 20.
So the product of other 3 factors should be greater than 16 and less than 20.
And we can have it from 18 only. Hence the number is 90.
The numbers between 80 and 100 having factor 5 are
<span>80,85,90,95,100</span>
<span>16=<span>24</span></span>
<span>17=17</span>
<span>18=2×3×3</span>
<span>19=19</span>
<span>20=<span>22</span>×5</span>
<span>90=2×<span>32</span>×<span>5</span></span>

Answer: x = 6
Step-by-step explanation:
First step is to distribute the 5(x + 2).
5x + 10 = 6x + 3x - 14
The 6x and the 3x on the right can be combined.
5x + 10 = 9x - 14
Now add 14 to both sides to isolate the 9x.
5x + 24 = 9x
Subtract 5x from both sides.
24 = 4x
Divide by 4 to get x by itself.
6 = x
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: y=6^x-3
It is a exponent form of graph, so first:
y=a^x-b
When b=0, the asymptote is y=0 but as the asymptote given is y=-3, b=-3
Second:
the y value increases 6, when x changes 0 to 1, so a=6
PEMDAS
3 ( x - 7 ) = 9 ( 4x + 5 )
3x - 21 = 36x + 45
-36
-33x - 21 = 45
+21
-33x = 66
------ ------
-33 -33
x = -2
Your answer should be -2
I hope this helps!
