Answer:

-81/3+32/5

-81×5+32×3/15

-243+96/15

-147/15

-49/5 Ans

To answer your question ("do you multiply the whole number too?"): Yes, you have to multiply the whole number as well. You can't just separate 1/3 from -8 and multiply it with 2/5, because the whole number is part of the mixed #. Whenever you multiply, add, divide, subtract, or do anything to two mixed numbers, you must include the whole term.

- - - - - - - - - -

Now your question is addition. Like I said, when you add them together, the whole number and the fractions count as one term.

So basically, -8 1/3 + 3 2/5...

- - - - - - - - - -

1) Find the LCM (least common multiple) of the denominators

The LCM of 3 and 5 is 15. To get from 3 to 15, you have to multiply 3 by 5. Now multiply the numbers of the fraction part only by 5.

1/3 --> 5/15 (as you can see, 1x5 = 5, 3x5 = 15)

Now for 2/5: To get from 5 to 15, multiply 5 by 3. Do the same thing to the numbers in the fraction

2/5 --> 6/15 (2x3 = 6, 5x3 = 15)

***TO CLARIFY, DO NOT MULTIPLY THE WHOLE TERM BY THE NUMBER***

Right: 2x3 = 6, 5x3 = 15, 6/15

Wrong: 2/5 x 5 = 2

- - - - - - - - - -

2) So now that we found a common denominator, change the two terms to -8 5/15 + 3 6/15 (because we had to find the LCM to make life a lot easier)

- - - - - - - - - -

3) We just add them together. Even though they are a term together, you can split them apart and add them together separately thanks to the commutative property of addition*.

Time to split it apart to make life a whole lot easier. -8 5/15 can be split apart into the two terms -8 and 5/15. For 3 6/15, it can be split into 3 and 5/15.

Two options from here on:

Set up a single equation: Put all the terms into one equation. -8 + 3 + 5/15 + 6/15. Solve by adding all the terms together in whichever order you prefer (again, thanks to the commutative property of addition)

It would result in the answer -4 4/15

Or...

Set up two separate equations: Set up an equation for whole numbers, and another one for fractions.

Equation 1: -8 + 3 = -5

Equation 2: 5/15 + 6/15 = 11/15

(6 + 5 = 11)

And we add the sums together. -5 + 11/15 = -4 4/15

And that's it!

- - - - - - - - - -

*Commutative Property of Addition: The sum of the numbers will NOT change even if you change the order of the addends

Answer:

17662.5 sq. feet

Step-by-step explanation:

We know that the formula for Area of a Circle is [tex]A = \pi (r)^2[/tex].

r = radius; d = diameter, which is r*2

And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.

150/2 = 75

The question said to keep [tex]\pi[/tex] =3.14, so then we plug in the equation-

[tex]A = 3.14 * 75^2[/tex]

Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-

[tex]A = 3.14 * 5625[/tex] (first doing the Exponent)

And we continue-

[tex]A = 17662.5[/tex] (then multiple)

So our answer is-

17662.5 sq. feet

I hope this helps!

Answer:6x2x2

Step-by-step explanation:

Answer:The length of midsegment is 34 units.

Given data:

The trapezoid KLMN, Such that KL = MN.

And , LM/KN = 8/9

Also, perimeter of KLMN = 132 units.

To find:

The length of midsegment (KM).

In the given problem, we can observe that KM is a transversal relative to parallel lines LM and KN. Which means,

Clearly, two base angles are equal. So, the triangles KLM and KMN are isosceles.

Taking the ratios of sides of two triangles as,

= KL : LM : MN : KN

= 8 : 8 : 8 : 9

The sum of ratio units is, 8 + 8 +8 +9 = 33. Then, the value of each ratio is,

Then the length of segment LM is,

And, length of segment KN is,

Then, the length of midsegment KM is obtained by taking the average of LM and KN as,

Thus, the length of midsegment is 34 units

Answer:

The client will save $392

The client save amount of  $392, if you install oak flooring instead of maple flooring.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that oak flooring costs $5.25 per square foot for materials. The maple flooring costs $7.00 per square foot for materials.

The room is 14 ft by 16 ft

The floor area will be;

14 x 16 = 224 sq ft.

Since oak costs $5.25 per sq ft, which means the total cost of an oak floor is;

5.25 x 224 = 1176 dollars.

Meanwhile, the maple flooring will have a total cost of 7 x 224 = 1568 dollars

then the savings is;

1568-1176 = 392

Answer:

1.195652174

Step-by-step explanation:

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below

We can work out that the divisor (46) goes into the first digit of the dividend (5), 0 time(s). Now we know that, we can put 0 at the top

If we multiply the divisor by the result in the previous step (46 x 0 = 0), we can now add that answer below the dividend

Next, we will subtract the result from the previous step from the second digit of the dividend (5 - 0 = 5) and write that answer below

Move the second digit of the dividend (5) down like so

The divisor (46) goes into the bottom number (55), 1 time(s), so we can put 1 on top

If we multiply the divisor by the result in the previous step (46 x 1 = 46), we can now add that answer below the dividend

Next, we will subtract the result from the previous step from the third digit of the dividend (55 - 46 = 9) and write that answer below
