NNADVOKAT [17]

7-4 (d-3)=23
7-4d+12=23 **multiply -4 with (d-3)***
7+12-4d=23
19-4d=23
-4d=23-19
-4d=4
d=4÷-4
d= -1

George has 36 cupcakes he has eight friends coming over to the party if he shares the cupcakes evenly with himself and all the g

Bogdan [553]

Answer:

Each person would get 4 cup cakes if all 8 friends attend the party.

Each person would get 12 cup cakes when 6 friends not attended the party.

Step-by-step explanation:

Given:

Total Number of cup cakes = 36

Number of friends coming to party = 8

Total number of people cakes need to distributed including George = 9

We need to find the number of cup cakes each person would get;

Solution:

Now we can say that;

number of cup cakes each person would get is equal to Total Number of cup cakes divided by Total number of people cakes need to distributed including George.

framing in equation form we get;

number of cup cakes each person would get = $\frac{36}{9}=4$

Hence Each person would get 4 cup cakes if all 8 friends attend the party.

Now Given:

Number of friends not attended the party = 6

So we can say that;

Total number of people cakes need to distributed including George = 9 - 6 = 3

So we can say that;

number of cup cakes each person would get = $\frac{36}{3} =12$

Hence Each person would get 12 cup cakes when 6 friends not attended the party.

The vertex of this parabola is at (2.-3). When the yvalue is -2, the xvalue is 5. What is the coefficient of the squared term in

tatiyna

Answer:

The coefficient of squared term is 1/9

Step-by-step explanation:

The vertex of parabola is (2.-3)

We know the vertex form of a standard parabola

$y=a(x-h)^2+k,\text{ where (h,k) is vertex}$

Plugging values of h and k, h= 2, k = -3

$y=a(x-2)^2-3$

Now, x=5, y=-2

$-2=a(5-2)^2-3$

$-2=9a-3$

$9a=1$

$a=\frac{1}{9}$

Thus, the coefficient of squared term is 1/9
