Which is not a correct way to rewrite this expression using the distributive
property?
(3x2 + 4x - 7)(x - 2)
A. (3x2 + 4x - 7)(x) + (3x2 + 4x - 7)(-2)
B. (3x)(x - 2) + (4x)(x - 2) + (-7)(x - 2)
C. (3x)(x) + (3x)(-2) + (4x)(x) + (4x)(-2)+(-7)(x) + (-7)(-2)
D. (3x2 + 4x - 7)(x) + (3x2 + 4x - 7)(x - 2)

Answer:

x = -5

2.1x+45.2 = -7.3-8.4x

10.5x+45.2 = -7.3

10.5x = -52.5

x = -5

Answer:

5,600,000 mg

Step-by-step explanation:

from kg to g ×1000

and from g to mg × 1000

so its 5.6 × 1 million

Answer:

5600000

Step-by-step explanation:

There's 1000000 mg in one kg.  Therefore you multiply 5.6 x 1000000 to get 5600000.

5.6 x 1000000

^ remember to move the decimal place over to the right once and then you take away a zero so you would be left with :

56 x 100000, this expression is easy to solve since you just need to count all the zeros and put that many zeros after 56 to get your final answer.

Total oranges (t) = 180

Not ripe = 15%

Now;

No. of oranges which are not ripe= 15% of 180

= (15/100)*180

= 27

Therefore, 27 oranges are not ripen.

   If the points like P, Q, R, S and T are collinear they will follow the segment addition postulate.

  Length of segments will be,

 PQ = 12 units

 QR = 14 units

 ST = 11 units

 PS = 43 units

 PR = 26 units

 RT = 28 units

It's given in the question,

And the lengths of different segments are,

By segment addition postulate,

PQ + QT = PT

PQ = PT - QT

PQ = 54 - 42

     = 12 units

QR + RS = QS

QR = QS - RS

     = 31 - 17 = 14 units

ST = QT - QS

     = 42 - 31 = 11 units

PS = PT - ST

     = 54 - 11

     = 43 units

PQ + QR = PR

12 + 14 = PR

PR = 26 units

RS + ST = RT

17 + 11 = RT

RT = 28 units

Each blinder cost will be $8.85.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

She spent a total of $49.50 on 5 binders and other miscellaneous items.

And, it $5.27 was spent on Miscellaneous items.

Now,

Let the cost on blinder = x

So, We can formulate;

⇒ 5x + 5.27 = 49.50

⇒ 5x = 44.23

⇒ x = 8.85

Thus, Each blinder cost = $8.85.

Problem 1

U = {2,3,8} is the entire universe. It's all of the numbers that exist in this framework. We ignore anything else.

A = {2,3,8} simply copies the universe and lists all the values we care about.

The complement of set A is any number not in set A. But because set A lists everything we care about, there's nothing left.

Therefore, the complementary set is empty.

We can write the empty set as { } which is a pair of curly braces with nothing between them. Not even 0 is part of this set.

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

Problem 2

U = {whole numbers} = {0,1,2,3,4,...}

This time the universal set is a bit more interesting, or at the very least, it's much bigger.

Set A is the set of odd whole numbers, so A = {1,3,5,7,9,...}. Notice how anything inside set A is also in set U. We can say set A is a subset of set U.

The complement of set A would be the set of even whole numbers {0,2,4,6,...}. This is the list of stuff not found in set A, but it's in the universal set.

Combing the evens and odds together will help form the set of all whole numbers.

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

Problem 3

set of whole numbers = {0,1,2,3,4,...}

Because h is a whole number, this means h must be selected from that set of values above and nowhere else.

We're then told that h < -2, but there is no such whole number that fits the description. Something like 4 < -2 is false. If we wanted negative values like this, then we'd have to expand to the set of integers.

Therefore, the set being described has nothing in it.

Answer:

∠ WOT = 85

Step-by-step explanation:

To find the measure of ∠WOT

we know that ∠UOV is 180 in the pic

so by letting ∠WOT = x

∠UOT + ∠WOT + ∠WOV = 180

30 + x + 65 = 180

95 + x = 180

x = 180-95

x = 85

so ∠ WOT = 85

Answer:

21/33

Step-by-step explanation:

1. 8+10+3+12=33 students in school

2. Now, you find how much students play violin or guitar

- 8 students only play violin

- 10 students only play guitar

- 3 students play both

3. 21 students in total who play violin or guitar

4. Since there are 33 students total, 21 out of 33 play those instruments

(If its not right, then adding in the 3 students who play both is probably a mistake :P)

Answer:

7/11

Step-by-step explanation:

There are a total of 33 students in this problem. The prompt tells us there are 8 students who play the violin, 10 students that play guitar, and 3 students who play both. Therefore, out of 33 students, there are 21 that play violin or guitar.

21/33 = 7/11

hi <3

84 + 4m = 276

subtract 84 from both sides:

4m = 192

divide both sides by 4:

m = 192/4 = 48

hope this helps :)

Hey there!

84 + 4m = 276

➡️ 4m + 84 = 276

SUBTRACT 84 to BOTH SIDES

4m + 84 - 84 = 276 - 84

CANCEL out: 84 - 84 because that gives you 0

KEEP: 276 - 84 because that helps solve for the m-value

276 - 84 = 192

NEW EQUATION: 4m = 192

DIVIDE 4 to BOTH SIDES

4m/4 = 192/4

CANCEL out: 4/4 because that gives you 1

KEEP: 192/4 because that helps you get the m-value

NEW EQUATION: m = 192/4

SIMPLIFY ABOVE AND YOU HAVE YOUR ANSWER

m = 48

Therefore, your answer is: m = 48

Good luck on your assignment and enjoy your day!

Answer:

358

Step-by-step explanation:

If we multiply the first equation by 3 on both sides we get 3a+3b=243.

If we multiply the second equation by 5 on both sides we get 5b+5c=115.

Adding these equations gives

(3a+3b)+(5b+5c)=243+115

Combine like terms:

3a+8b+5c=358

Another way.

Find numbers to satisfy the criteria.

a+b=81

b+c=23

Choose a=80.

This forces b=1 since 80+1=81.

If b=1 and b+c=23, this forces c=22.

Now plug into 3a+8b+5c.

3(80)+8(1)+5(22)

240+8+110

358

Answer:

128

Step-by-step explanation:

a+b =81

a =81-b

b+c= 23

c =23-b

3a+8b+5c

= 3(81-b) +8b+5(23-b)

=243-3b+8b+ 115-5b

=128+5b-5b

=128
