Sue had 5 identical bags of candy to share with the crew. Twenty-five pieces of candy disappeared. Ted had 4 bags with the same
inna [77]

Answer:

Each bag originally had 35 pieces of candy

Step-by-step explanation:

Since the bags are identical, Let them Number of candies in each bag sue had be x. Thus, she had 5x candies. Since she lost 25 pieces, then she now has;

5x - 25 candies left.

We are told that Ted had 4 bags with the same number of candies like Sue had. Thus, he has 4x candies.

He mysteriously found 10 additional pieces. Total Ted now has is;. 4x + 10

Finally, we are told that Sue and Ted now have an equal number of candies.

Thus;

5x - 25 = 4x + 10

Rearranging, we have;

5x - 4x = 25 + 10

x = 35

Thus, each bag originally had 35 pieces of candy

Please do not do this for the points, it's rude and disrespectful. I really need help.
professor190 [17]

Answer:

1) A = -10, B = -4, distance = 6 units

2) Eqaution: 3(x+4) = 60

Tyler's age: 16 Samantha: 20

3) x < 1

Draw a number line from 1 towards left, with an open circle at x = 0

Step-by-step explanation:

1) A/2 = -5

A = -5×2 = -10

8 = -B/0.5

8×0.5 = -B

B = -4

Distance = -4 - (-10) = -4 + 10 = 6

2) S = 4 + x

3s = 60

3(4 + x) = 60

3S = 60 S = 20

4 + x = 20 x = 16

3) x/2 + ¼ < ¾

x/2 < ¾ - ¼

x/2 < ½

x < 1

Draw a number line going towards left from 1, with an open circle at x=1 because x=1 is not included
