Answer: Choice C) Harold

Darren is correct because he subtracted c from both sides

Julie is correct because she multiplied both sides by H, and then divided both sides by L

Brenda is correct because she multiplied both sides by r

Harold is not correct. We can see this with a counter example. If A = 7 and h = 1, then the first equation Harold wrote leads to b = 14. Now plug those same values into the second equation and we get h = 2b/A turning into 1 = 2*14/7 and that simplifies to 1 = 4, which is a false statement. This contradiction is one example why the two equations Harold wrote aren't equivalent.

Use a letter to represent the unknown Twenty packs of fruit snacks come in a box. Each pack weighs 6 ounces. Students eat some.

777dan777 [17]

Answer:

The students have eaten 72 ounces of fruit snacks.

X = 72 ounces

Step-by-step explanation:

There are total 20 packs of fruit snacks

The weight of each pack is 6 ounces.

Let us first find the total weight of the snacks.

Total weight = 6*20

Total weight = 120 ounces

Let X represents the ounces of fruit snacks that students have eaten.

Let Y represents the 48 ounces of fruit snacks left in the box

Total weight = X + Y

120 = X + 48

X = 120 - 48

X = 72 ounces

Therefore, the students have eaten 72 ounces of fruit snacks.

Solve using your choice of graphing, substitution, or elimination

antiseptic1488 [7]

Answer:

x = 110, y = 153.

Step-by-step explanation:

4x - 3y = -19 Multiply by 2

3x - 2y= 24 Multiply by 3.

8x - 6y = -38

9x - 6y = 72 SUBTRACT

-x = - 110

x = 110

Substitute for x :

3(110) - 2y = 24

2y =330 - 24

2y = 306

y = 153.
