Answer:

2 =x

Step-by-step explanation:

2 - 4x = 3x - 12

Add 4x to each side

2 - 4x+4x = 3x+4x - 12

2 = 7x-12

Add 12 to each side

2 +12 = 7x - 12+12

14 = 7x

Divide each side by 7

14/7 = 7x/7

2 =x

Answer:

x = 2

Step-by-step explanation:

Step 1: Write out equation

2 - 4x = 3x - 12

Step 2: Add 4x on both sides

2 - 4x + 4x = 3x + 4x - 12

2 = 7x - 12

Step 3: Add 12 on both sides

2 + 12 = 7x - 12 + 12

14 = 7x

Step 4: Divide both sides by 7

14/7 = 7x/7

2 = x

Step 5: Rewrite

x = 2

How do you interpret algebraic expressions in terms of their context
NNADVOKAT [17]
Well, it really depends on the context they are in. For instance,
2x^2 + 3x is different than 2xyt + 3xy + 2xyt or
y = 2x + 5 or 2x^3 + 2x^2 + 4x + 4 They all are interpret differently. For instance, one is a line, another is a square and one is a cube.

A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says t
solniwko [45]

Answer:

The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.

Step-by-step explanation:

Given that:

Number of apples already available with Owner = 200

Number of bags of apples ordered with 12 apples each = 19

Number of apples ordered = 12 \times 19 = 228

OR

Rounding off 19 to 20:

Number of apples ordered  = 12 \times 20 = 240

Around <em>240 apples were ordered</em>.

Number of bags of apples with 8 apples each, sold = 42

Number of apples sold = 42 \times 8 = 336

Rounding off 42 to 40, <em>number of apples sold = around 320</em>

<em></em>

Therefore, 80 more apples were sold than that of apples bought.

So, according to the estimate, there will be 80 fewer apples left than they started with.

<em>Correct answer is:</em>

The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with
