How to answer this problem solving question: Anita and Terry ride the subway on sundays to visit their grandparents. There are 2 enterances to the subway from the street, north and south. Inside each entrance is an escalator, elevator and stairway leading to the first level. On the first level there are eight gates. At each end of thr first level (north and south) there is an escalator, elavator, and a stairway. These lead directly to the trains. How many different ways can Anita and Terry go frim street level to the trains?

Answer:

The original solution of the equation

  x=6

Adding 3 on both sides, gives

x+3=6+3

x+3=9

 x=9-3

So,Addition of 3 on left hand side or subtraction of 3 from 9 in right hand side gives solution x=9.

Answer:

She needs 3 cups flour to make 30 biscuits.

Step-by-step explanation:

Consider the provided information.

jaylen is making biscuits using the recipe below 2 c flour,4tsp baking soda,1/2tsp,salt,2tbs lard,1c milk,1 small egg it makes 20 biscuits

That means for making 20 biscuits she need 2 cups of flour.

Now she wants to make 10 more biscuits so that 20+10=30.

For 20 biscuits she needs 2 cups of flour that means for 10 biscuits she needs only 1 cup of flour as 20 is half of 10.

Thus, for 30 biscuits she needs:

2 cups + 1 cup = 3 cups flour

Hence, she needs 3 cups flour to make 30 biscuits.

The coordinates of the other two vertices are:

(1/2 + √98, 3/2)

(1/2, 3/2 - √98)

If A(-3, -2) and C(4, 5) are the endpoints of a diagonal of a square, and since a square has equal sides and right angles, you can find the other two vertices by considering the properties of a square.

Let's calculate the midpoint of AC, which will be the center of the square. The midpoint of AC can be found by averaging the coordinates of A and C:  

Midpoint M = ((-3 + 4) / 2, (-2 + 5) / 2) = (1/2, 3/2)

Now, we know the center of the square is at (1/2, 3/2).

To find the other two vertices, we'll move from the center in different directions.

Since a square has four equal sides, the distance from the center to any corner will be the same as the distance from A to C.

The distance between A and C can be found using the distance formula:

So, the distance from the center to any corner is √98.

Now, we can find the other two vertices by moving √98 units from the center in different directions.

One vertex is √98 units to the right of the center: (1/2 + √98, 3/2)

One vertex is √98 units below the center: (1/2, 3/2 - √98)
