Answer:

Point B is (3, 8)

Step-by-step explanation:

Hello, Jacky,

Note that points A and C have the same x-coordinate and thus lie on the same vertical line, which is x = 3.  To determine the length of this directed line segment, we need only subtract 4 from 9, obtaining 5.

Now if we start at (3,4), move up 4 units along this vertical line, plot a point there, and finally move 1 more unit along this line to C(3, 9), we will have partitioned the line in the ratio 4:1.  To find the coordinates of this point, we simply take x = 3 (see above) and add 4 to y = 4), obtaining the point (3, 8).  This is Point B.

Point B is (3, 8)

1. A bag of 12 oranges costs $2.99. What is the cost per orange?
Reil [10]

Answer:

1- $ 0.25.

2- $ 26.25.

3- $ 1.73.

Step-by-step explanation:

1- Given that a bag of 12 oranges costs $ 2.99, to determine what is the cost per orange, the following calculation must be performed:

2.99 / 12 = X

0.249 = X

Thus, the cost of each orange is $ 0.25.

2- Given that 4 slices of pizza cost $ 10.50, to determine what is the cost of 10 slices of pizza at this rate, the following calculation must be performed:

10.5 / 4 x 10 = X

2.625 x 10 = X

26.25 = X

Thus, the cost of 10 slices of pizza is $ 26.25.

3- Given that 4 pieces of candy cost $ 0.99, to determine what is the cost of 7 pieces of candy at this rate, the following calculation must be performed:

0.99 / 4 x 7 = X

0.2475 x 7 = X

1.7325 = X

Thus, the cost of 7 pieces of candy is $ 1.73.
