Answer: x= -3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−4)+3x−9x=6−(2x+5)+8x
(5)(x)+(5)(−4)+3x+−9x=6+−2x+−5+8x(Distribute)
5x+−20+3x+−9x=6+−2x+−5+8x
(5x+3x+−9x)+(−20)=(−2x+8x)+(6+−5)(Combine Like Terms)
−x+−20=6x+1
−x−20=6x+1
Step 2: Subtract 6x from both sides.
−x−20−6x=6x+1−6x
−7x−20=1
Step 3: Add 20 to both sides.
−7x−20+20=1+20
−7x=21
Step 4: Divide both sides by -7.
−7x
−7
=

Problem 1 (3 + 3 + 3 = 9) Suppose you draw two cards from a deck of 52 cards without replacement. 1) What’s the probability that both of the cards are hearts? 2) What’s the probability that exactly one of the cards are hearts? 3) What’s the probability that none of the cards are hearts? Make sure to clearly define your probabilistic events and mathematically show how different probability laws and rules that you learned in class could be applied to solve the problems.
Answer:
0.0588235; 0.3823529; 0.5588235
Step-by-step explanation:
Given that:
Total number of cards = 52
Total number of hearts = 13
Probability = required outcome / Total possible outcomes
Two cards are drawn without replacement :
1) What’s the probability that both of the cards are hearts?
First draw :
P(hearts 1) = 13 / 52
Second draw :
P(hearts 2) = 12 / 51
P(both cards being hearts) :
(13 /52) × (12/51) = 156 / 2652 = 26/442 = 13 / 221 = 0.0588235
2) What’s the probability that exactly one of the cards are hearts?
First draw being hearts, 2nd not hearts Or First draw not hearts and 2nd being hearts
P(first draw hearts) = 13 /52
P(2nd not hearts) = 39/51
13/52 × 39/51 = 0.1911764
P(first not hearts) = 39 /52
P(2nd being hearts) = 13 / 51
39/52 × 13/51 = 0.1911764
Hence, (0.1911764 + 0.1911764) = 0.3823529
3) What’s the probability that none of the cards are hearts
P(first draw, no hearts) = 39/52
P(second draw, no hearts) = 38/ 51
39/52 × 38/51 = 1482 / 2652 = 0.5588235

Simplify the numerical expression.
1 + 24 + ( + 3) = 1
The expression has a value equal to ???
Answer:
27
Step-by-step explanation:
Given expression :
1 + 24 + ( + 3) = 1
Bring the number 1 to the left side of the equal sign. The positive 1 becomes negative 1 when brought towards the left side of the equal sign.
1 + 24 + ( + 3) - 1 = 0
Now, opening the bracket, we get
1 + 24 + 3 - 1 = 0
Negative 1 and positive 1 will get cancel
24 + 3 = 0
or 27
Therefore, the value of the numerical expression 1 + 24 + ( + 3) = 1 is 27.

unghiurile ∢AOB și ∢COD sunt unghiuri opuse la vârf, O ∈ AC, iar PO ⊥ BD, P∈ Int ∢AOD. Dacă ∢COP = 133°, aflați măsurile unghiurilor ∢AOB și ∢BOC.
Răspuns:
<AOB = 43 ° și <BOC = 137 °
Explicație pas cu pas:
Găsiți diagrama atașată pentru o mai bună explicație a întrebării.
Din diagramă, <COP = <DOP + <COD
Deoarece <DOP = 90 ° și <COP = 133 °, la înlocuire
133 ° = 90 ° + <COD
<COD = 133 ° -90 °
<COD = 43 °
Deoarece <COD = <AOB (unghiuri direcționate opuse), deci <AOB = 43 °
Pentru <BOC:
Suma unghiurilor pe DBO dreaptă este de 180 °.
<BOC + <COD = 180 °
Dat <COD = 43 °
<BOC + 43 = 180 °
<BOC = 180 ° -43 °
<BOC = 137 °
Prin urmare, <AOB = 43 ° și <BOC = 137 °

Find the original price of a pair of shoes if the sale price is $84 after a 30% discount.
Answer:
Original price = $ 120Step-by-step explanation:
To find the original price given the new price and percentage discount we use the formula
[tex]original \: \: price = \frac{100}{(100 - x)} \times new \: \: price \\ [/tex]
where
x is the percentage discount
From the question
new price = $ 84
% discount = 30%
Substitute the values into the above formula and solve
That's
[tex]original \: \: price = \frac{100}{100 - 30} \times 84 \\ = \frac{100}{70} \times 84 \\ = \frac{10}{7} \times 84 \\ = 12 \times 10[/tex]
We have the final answer as
Original price = $ 120Hope this helps you

A researcher is studying psychological factors in artistic achievement among teenage boys. One variable he is particularly interested in is perseverance.
1. What information does a measure of variability for the variable perseverance convey?
2. What is the most common value for the variable perseverance among teenage boys?
3. How spread out are the values for perseverance among teenage boys?
4. What is the central tendency for the variable perseverance among teenage boys?
5. What is the average value for the variable perseverance among teenage boys?
Answer:
How spread out are the values for perseverance among teenage boys?
Step-by-step explanation:
1. What is the most common value for the variable perseverance among teenage boys? - This deals with MODE. Hence, this option is not correct because the problem does not deal with a specific value of the perseverance variable but about the variability of the perseverance variable
2. What is the central tendency for the variable perseverance among teenage boys? - This deals with the MEDIAN. However, since the problem is about determining dispersion, and not a central tendency, it is incorrect.
3. What is the average value for the variable perseverance among teenage boys? - This deals with the MEAN. Hence, it is not correct either.
However, since the given situation deals with a measure of variability for the variable perseverance conveys, the correct answer is "How spread out are the values for perseverance among teenage boys?" Because it measures how far are the observation away from the center.

35,892 rounded to nearest 10
Answer:
35,890
...........
Answer:
35,890
Step-by-step explanation:
The 9 is the tens digit.
Every digit to the right of 9 becomes 0.
Start with: 35,890
Now you check the first digit to the right of the tens digit. If it is from 5 to 9, the tens digit goes up 1. If it is from 0 to 4, the tens digit remains the same.
In this case, the digit to the right of the tens digit is 2. Since 2 is from 0 to 4, the 9 remains as is and does not go up by 1.
Answer: 35,890

Grains of sand are very small, there being about 3000 grains in one cubic centimeter (cm3) of sand. A cm3 is a small cube measuring one cm on each side and is about the size of your little finger from the fingernail onward. Given that there are one million cubic centimeters (cm3) in one cubic meter (m3), how many grains are there in 1 m3of sand
Answer:
The value is [tex]x = 3.000 * 10^9 \ grains[/tex]
Step-by-step explanation:
From the question we are told that
[tex]1m^3 = 10^6 cm^3[/tex]
And that
[tex]3000 \ grains \ of \ sand \ is \ in \ 1cm^3[/tex]
So the number of sand grain that is in [tex]1m^3[/tex] is mathematically evaluated as
[tex]x = 3000 * 10^6 \ grains[/tex]
=> [tex]x = 3.000 * 10^9 \ grains[/tex]

2 to the Third power -(30÷5) +9
Answer:
11
Step-by-step explanation:
2^3-(30/5)+9
First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:
P- parentheses
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
so 30/5 = 6 and plugged in is:
2^3-(6)+9
Next, we do exponents:
2^3 = 2x2x2 = 8
plugged back in:
8-(6)+9
Now, we do the math from left to right so:
8-6=2
2+9=11
11 is your answer

what does B equal ? please help me
Answer:
108
Step-by-step explanation:
These are alternate exterior angles and alternate exterior angles are equal when the lines are parallel
A = B
6x+18 = x+93
Subtract x from each side
6x+18 -x = x+93-x
5x +18 = 93
Subtract 18 from each side
5x + 18-18 = 93-18
5x =75
Divide by 5
5x/5 = 75/5
x = 15
Angle B
x+93
15+93
108
Answer:
Solution given:
<A+<B=180°[ alternate exterior angle are equal]
6x+18=x+93
6x-x=93-18
5x= 75
x=15
now
<B=15+93=108°
