Answer:
x = -2
Step-by-step explanation:
6(x+7)=30
6x+42=30
6x=-12
x=-2
Step-by-step explanation:
Hey there!!
According to the question,
One number is 7.
Let another no. be x.
So, the condition is 6(x+7)= 30
Now,
6(x+7) = 30
6x +42 = 30
6x = 30-42
[tex]x = \frac{ - 12}{6} [/tex]
Therefore the no. is -2.
Check,
6(-2+7)= -12 + 42 = 30 { they gets subtracted but sign remains (+) only }.
Hope it helps....

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°

11. Julie wants to go shopping for new clothes. She
has a budget of $100. She spends $45 on a new pair of
jeans and $11 on each new shirt.
The equation 100 = 45 + 11s represents s, the number
of shirts Julie bought.
Write in complete sentences the first 2 steps that Julie
would use to solve this equation.
Answer:
5
Step-by-step explanation:
1. subtract 45 from both sides 55 = 11s
2. Divide by 11 on both sides [tex]\frac{55}{11} =\frac{11s}{11}[/tex]
3. And now you have 5 = s

Evaluate the function.
f(x) = 5-(7+x)+2, find f(3).
Answer:
-3
Step-by-step explanation:
For f = 5 - (7 + x) + 2, substitute x with 3.
f = 5 - (7 + 3) + 2
f = 5 - 10 + 2
f = -5 + 2
f = -3

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
8-4(2 - 5x) - 3(2x - 3) = 9 + 14x

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]

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
PLEASE HURRY WILL GIVE BRAINLIEST Kaylee is buying bagels for a family gathering. Each bagel costs $0.75. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is A(x) =0.75x .
So A(12) = 9, meaning 12 bagels will cost 9 dollars.
Step-by-step explanation:
Please give me THANKS and BRAINLIES
Have a good day
The relationship between the total cost and the number of bagels purchased will be;
⇒ y = $0.75x
Where, y is total cost and x is number of bagels purchased.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Kaylee is buying bagels for a family gathering.
And, Each bagel costs $0.75.
Now,
Let number of bagels purchased = x
Total cost to purchased bagels = y
So, We get;
The relationship between the total cost and the number of bagels purchased;
⇒ y = $0.75x
Thus, The relationship between the total cost and the number of bagels purchased is;
⇒ y = $0.75x
Where, y is total cost and x is number of bagels purchased.

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 °
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
