Anything with a value of w=3.5 would be equivalent.

To solve this, we cannot have a variable on both sides, so we will subtract 12w from both sides:
12w - 27 - 12w = -34 + 14w - 12w
-27 = -34 + 2w

Now add 34 to both sides:
-27+34 = -34 + 2w + 34
7 = 2w

Divide both sides by 2:
7/2 = 2w/2
3.5 = w

Answer:

Going to piggyback off of the "answer" given above me. Your best bet is B. -47-10w=-9w-40-3w

Step-by-step explanation:

Simplify both sides of the equation like you did with the original problem.

Then, you should get w= 3.5 (which is the same solution as the previous equation.)

Hope this helps!

Solve for W (W/-5) -4=-2

Simora [160]

Answer: $\Large\boxed{W=-10}$

Step-by-step explanation:

Given equation

$(\dfrac{W}{-5} )-4=-2$

Add 4 on both sides

$(\dfrac{W}{-5} )-4+4=-2+4$

$(\dfrac{W}{-5} )=2$

Multiply -5 on both sides

$(\dfrac{W}{-5} )\times (-5)=2\times(-5)$

$\Large\boxed{W=-10}$

Hope this helps!! :)

Can someone Please Help? The side of a square is Three raised to the five halves power inches. Using the area formula A = s2, de

Talja [164]

The side of the square has a measurement given as 3^5/2. We calculate the area using the equation A = s². We calculate as follows:

A = (3^5/2)^2
A = (3^5)
A = 243 in²

Hope this answers the question. Have a nice day.

Cheese costs $4.40 per pound. Find the cost per kilogram. (1kg = 2.2lb)

MakcuM [25]

Answer:

The cost is $9.70 per kilogram.

Step-by-step explanation:

This can be solved by a rule of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.

In this problem, the measures are the weight of the cheese and the price. As the weight increases, so does the price. It means that this is a direct rule of three.

Solution:

The problem states that cheese costs $4.40 per pound. Each kg has 2.2 pounds. How many kg are there in 1 pound. So:

1 pound - xkg

2.2 pound - 1 kg

$2.2x = 1$
