It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =

\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x
when we divide 1)/2), k gets cancelled

x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
Answer:
$50 - d = $22.50
Step-by-step explanation:
Since she's receiving a change, it means that d is smaller than $50, therefore, it will be deducted from it to give the change.
Answer:
12:45
10:45 + 15 minutes = 11:00
11:00 + 1 hour and 45 minutes = 12:45
Think of it as:
11:00
+1.45
———
12:45
The range of the answer is [-3,infinity) and {yly>=-3}
Answer:
A. length = 23 cm; width = 5 cm
Step-by-step explanation:
So if 4 times the width would be
and 3 more than would be
, the equation would be
. If the perimeter is 56, then the new equation,
can be formed. This simplifies to
, then to
, then to
, and finally,
. So the width is 5, and now plug it into the first equation.
, becomes
, becomes
.
So the dimensions are: length = 23 cm, width = 5 cm.
*And just to be sure,
which is correct.
