Can anyone help me pls. Show your work.

Answer:

489 or -113

Step-by-step explanation:

Whats 30 times 30 plus 45 minus 456

rewrite in terms of numbers:

30 * 30 + 45 - 456

remember the order of operations and solve:

30 * 30 + 45 - 456

=900 + 45 -456

= 945 - 456

= 489

the answer could change depending on the placement of parenthesis, such as if the equation was:

30 * (30 + 45 -456)

solve with the order of operations:

30 * ( 30 + 45 - 456)

= 30 * (75 - 456)

= 30 *(-381)

= -11430

Answer:

92.5

Step-by-step explanation:

96 93 93 92 91 84 are your highs and to find the mean you cross one on each side until there is only one or 2 left.

you are left with 93 and 92 so you add them together and divide by two to get 92.5 which is your answer

Answer:

b

Step-by-step explanation:

4 2/3= 12/3+2/3=14/3

3 2/1=7/2 but you have to flip it

so you end up with 14/3*2/7

4 2/3 = 14 / 3

3 1/2 = 7/2

An easy way to divide fractions is to find the reciprocal of the second fraction.

The reciprocal of 7/2 = 2/7

Then we multiply straight across.

14/3 × 2/7

Answer

A- 22 square units

B- 28 square units

C- 18 square units

Step-by-step explanation:

A. You can break it up into 3 different rectangles

(1*2)+(2*4)+(2*6)=22

B. You can first start by finding the area then subtracting the the places where it is not covered.

So the area of the whole square is 6*6=36

Now you can subtract the small squares 2*2=4.

This will be put 2 times as there are two small squares.

So you will subtract 8 square units from 36.

36-8=28

C- You can decompose C into a triangle and a rectangle.

The area of a triangle is 1/2*width*height. When you plug the dimensions in you get 1/2*6*2=6 square units.

Now to find the rectangle. The formula is width*length. Plug the dimensions in and you get 2*6=12 square units.

Just add those two together and you get 18 square units.

do you want me to explain what the distributive property is????

i'm confused-

Answer:

The distributive property of multiplication states that a ( b + c ) = a b + a c . It's often used for equations when the terms within the parentheses can't be simplified because they contain one or more variables.

Answer: d=20/3

Step By Step:

Step 1, Simplify:

12-3/4(d+16)=-5

(-3/4)d+(12-12)=-5

(-3/4)d=-5

Step 2, Multiply each side by 4/(-3)

(4/-3)*(-3/4)d=(4/-3)*-5

d=20/3

Answer:

the tens place

Step-by-step explanation:

The tens place value would help you write 50/1,000 as 5/100 because to get 50 to 5, you would need to get rid of the tens place. In other words, you would need to divide by 10.

50 divided by 10 is 5

1,000 divided by 10 is 100

Answer:67

Step-by-step explanation:

Answer:

$190

Step-by-step explanation:

you just have to add all the numbers up- 62.89+48.26+81.99 which is about 193 so you would round down

Answer:

I believe it's the second one

Step-by-step explanation:

The greatest common factor of 44 and 40 is four, so 4 times 11 is 44 and 4 times 10 is 40. that gives you 44 + 40

Answer:

3,800

Step-by-step explanation:

Here's how I believe I got the answer

Since the whole area is 7,600 cm2

I think that is saying that you divide in half, since that's the area. Your probably going to think about the perimeter, which divided by two, you get 3,800

My bad if I'm wrong!

Answer:

3,800

Answer:

r < 1/3

Step-by-step explanation:

Answer:

r<1/3

Step-by-step explanation:

21r / 21 = r

7 / 21 = 1/3

Since 21r is less than 7, using the equations shown above, we can also see r (singular) is less than 1/3.

Answer: Subtraction property of equality.

Step-by-step explanation:

n + 9 = -3

You are trying to move 9 from one side to the other. To do that, you have to do the inverse operation and subtract nine from both sides. Your result would be n = -12.

Answer:

whats the question

Step-by-step explanation:

Okay, suppose You know, 32 is between what? two perfect squares? What are perfect squares? Well, a number of times itself gives me, so like, four times itself is 16, 5 times itself is 25, 6 times itself is 36, So 32 is the closest to 25 In 36. So I'm gonna put 25 Smalling number and 36. And what I could do with this inequality is I could take the square root of all three Side. So square to 25 is in between square to 32 is in between square to 36. So square 25. What himself gives me 25 5 Is in between the square to 32 and what himself gives me 36 6. So that must mean the Square 32 is in between the Avengers five and so.

Answer:

Step-by-step explanation:

If 180 is the factor of 105 m, then the factors of 180 should also be the factors of 105 m.

Factors of 180 = 15 * 12

Factors of 105 m = 15 * 7 * m

The least value of m is  = 12

Step-by-step explanation:

You move the decimal point 2 places to the left

9.51 --->.951--->.0951

Answer:

Yes, it is reasonable

Step-by-step explanation:

Her result is reasonable because you can have a smaller positive then a negative for example 4 + -9 = -5

Answer:

it isn't

Step-by-step explanation:

It isn't reasonable. For example, 4 - -4 is equal to 8 because when two negative signs are next to each other, it becomes positive.

Step-by-step explanation:

Answer: Q1: D. Distribute 3 through the parenthesis

Step-by-step explanation:

As for the second question, I am not sure how to begin. Sorry

Answer:

For the first question: 3(p - 3) = 2p + 7, the first step would be to distribute 3 to both terms in the parentheses

For the second question:

6n + 11 = -7 + 3n

-3n               -3n

3n + 11 = -7

      -11    -11

3n = -18

3n/3 = -18/3

n = -6

Check:

6(-6) + 11 = -7 + 3(-6)

-36 + 11 = -7 + -18

-25 = -25, since these match n definitely equals -6

Step-by-step explanation:

Answer:

1,371.8

Step-by-step explanation:

Here's how I got it

Since the whole square feet is 6859, and they charge 5$ per square feet, I believe if you divide 6859 divided by 5 you get 1,371.8

Sorry if I got it wrong!

Answer:

$1805 i think

Step-by-step explanation:

Cube root the volume of the room (6859) which equals 19. do 19x2=361. Do 361x5=1805. So the total would be $1805 i believe
