ax+z=aw-y for a

man i hate math ngl- please send help

Answers

Answer:

its a =y+z/w-x

Step-by-step explanation:

First, subtract

z and a w from each side of the equation to isolate the

a terms while keeping the equation balanced

than factor a A from each term on the left side of the equation

now divide each side of the equation by x-w to solve for a while keeping the equations balanced

you then multiply the right side of the equation by a form of 1 to rewrite the expression as

a=-1/-1 x -y & -z/ \-x/-w

than you remove the ones add a addition to y and the z and then you flip the x and the why and add multiplication

Subtract z first and aw from the equation to isolate the a terms while keeping the equation balanced.

ax-aw= -y-z

Then factor an a from each term.

a(x-w)=-y-z

Now, divide each side of the equation by x-w.

a = -y-z/x-w

Multiply the right side of the equation by a form of 1 to rewrite the expression.
The picture linked is the answer.

Here are the ones to pick from
1. -2 + -2 +6 +x
2. 6(-2 +x)
3. 6(-2 +x)
4. -3 (1 - 2x)

Answers

Answer:

Option #4

Step-by-step explanation:

Expand option #4

=-3(1-2x)

=-3 -2x*-3

=-3+6x which is what your original equation was.

becoz it is a multiple choice, we can go by elimination, hence when we expand #4, we will get -3+6x

the difference between solving for surface area and solving for volume

Answers

Answer: The Surface Area is a sum total of Area of the planes that form a surface/shape while Volume is the space enclosed within a figure/shape/surface.

The Surface Area is a 2-Dimensional concept with units m², cm² or mm² where as Volume is a 3-Dimensional concept with m³, cm³ or mm³ as units.

Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

Answers

Answer:

There are 23 cats for every 36 dogs at the city pound

Step-by-step explanation:

This means that for every group of 92 cats at the city compound there is a group of 144 dogs. So it also means that for every group of 23 cats there is a group of 36 dogs.

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

To solve -9 - 16m = 7, what steps would you use?

(divide by; multiply by; add; or subtract) 9

(divide by; multiply by; add; or subtract) -16

Answers

Answer:

add 9

divide by -16

Step-by-step explanation:

I would add nine to both sides, making it -16m=16.

Then, I would divide by -16 on both sides to isolate the m.

You would add 9 then divide by 16, you do the inverse, which is the opposite. + -> - (vice versa) and x -> division (vice versa)

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

Answers

Answer:

1 1/5.

Step-by-step explanation:

To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".

For the problem 24/25 ÷ 4/5,

You KEEP the first fraction as is, so 24/25

Then, you SWITCH the sign from division to multiplication.

Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.

The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)

24 * 5 = 120

25 * 4 = 100

the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.

Keep change flip if not noted you should

Answer: 4

==========================================================

Explanation:

Locate -5 on the x axis number line. Draw an arrow going upward until you reach the function curve. Then move horizontally until you reach the y axis. You should arrive at y = 4. Therefore, f(-5) = 4 and it means the point (-5, 4) is on the function curve.

Check out the diagram below.

It is 4 because when you find the value of f it equals 4 and then the negative 5 would addd up to the 4

Answer:

Step-by-step explanation:

So you have to remember, area is LxW - Lenth x Width.

Also remember base is bxh - Base x height.

T he rectangle has a area already which is 3x3 = 6 but remember you also have to find the base. So,

you do Area = 50.4 yd²

Step-by-step explanation:

Base dimension of container = 4⅕ by 1⅓ yd

Array: 3 * 3 containers without space

Area covered by the containers

First, it'll be assumed that the container has a rectangular base.

The dimension of the base is measured out as follows:

Length, L = 4⅕ yd

Width, W = 1⅓ yd

Note that this can also be interchanged.

Next, is to calculate the area of 1 container..

Area = 4⅕ yd * 1⅓ yd

Convert mixed fractions to improper fraction

Area = 21/5 * 4/3 yd²

Area = 84/15 yd²

Area = 28/5 yd²

Area = 5.6 yd²

Next, is to calculate the area of the 3 by 3 containers.

Given that the container formed a 3 by 3 array;

This means that there 3 * 3 containers

3 * 3 = 9 containers.

Area of the 9 containers = 9 * Area of 1 container.

Area = 9 * 5.6 yd²

Area = 50.4 yd²

the area covered by the containers is 50.4 yd²
