Let v = number of video's she bought
Let c = number of CD's she bought
v+c=16
1495v+1688c=9355
Multiply both sides of (1) by 1495
and subtract (1) from (2)
-1495v-1495c=-8970
193c=386
c=2h
For this case we define the following variable:
<em>x: unknown number
</em>
We then have the following equation:

From here, we clear the value of x.
We have then:

Answer:
An irrational number that can be multiplied by negative square root of 41 to get a product that equals 1 is:

Answer:
4 meters
Step-by-step explanation:
Assuming that the garden is a rectangular garden, its area would be length ×width.
Let the length be L meters and the width be W meters.
Area= L ×W
48= LW -----(1)
Given that the length is 3 times the width,
L= 3W -----(2)
Substitute (2) into (1):
48= 3W(W)
3W²= 48
Divide both sides by 3:
W²= 48 ÷3
W²= 16
Square root both sides:

W= 4 (reject negative as width cannot be a negative number)
Thus, the width of the garden is 4 meters.
