Let x = sue
and then let 3x-84 = marcia
therefore
(x)+(3x-84)=132
4x-84=132
4x=216
x=54
however just solving for x doesnt completely solve. it only shows sues money because x = sue
for marcia
3x-84
3(54)-84
162-84
78
therefore Marcia has 78$.
Hi there!
Everything looks correct except for the step to get to -6x < 36. Here you put multiplication property of order, and to get here you have to add 30 to both sides, so it would actually be the addition property of order.
I hope I helped!
Answer:
M(5,2)
Step-by-step explanation:
We use the midpoint rule:

We just have to find the arithmetic mean of the x and y-coordinates.
The endpoints of CD are given as C(3,−5) and D(7, 9).
We substitute these values to get:



Therefore the coordinates of the midpoint M of CD are (5,2)
<u>Given</u>:
Given that the angles of the kite.
The opposite angles of the kite measures (3y + 14)° and (y + 50)°
We need to determine the value of y.
<u>Value of y:</u>
We know the property that the opposite angles are equal.
Thus, applying the property, we have;

Subtracting both sides of the equation by y, we have;

Subtracting both sides of the equation by 14, we get;

Dividing both sides of the equation by 2, we get;

Thus, the value of y is 18.
The mean doesn't have outliers, and if you're looking for a perfect middle of your data, the median is the best.
