Solve the equation that represents: The difference of five times a number and 6 is -2.
Answer:
5n-6= -2
Step-by-step explanation:
The difference of...... this means its asking us to subtract one number from another number
5 times a number...... that means 5n
6..... since it said DIFFERENCE, it would be -6
is -2........ this means the answer to the equation is -2
So the equation is 5n-6= -2

Solve:
n/2 - 10=6
((Show work))
*Sorry I forgot how to do this, and please answer this correctly*
Answer:
32
Step-by-step explanation:
(n/2) − 10 = 6
Add 10 to both sides.
n/2 = 16
Multiply both sides by 2.
n = 32
Answer:
n=32
Step-by-step explanation:
n/2 - 10=6
add 10 on both side
n/2 +10-10=6+10
n/2=16
multiply both side by 2
n/2×2=16×2
n=32
There are 80 tickets in a bag and the ratio of winning tickets to losing tickets is 2 : 8. How many of each kind of ticket are in the bag?
Given:
Total number of tickets = 80
Ratio of winning tickets to losing tickets is 2 : 8.
To find:
The number of tickets of each kind in the bag.
Solution:
Let the number of winning and losing tickets are 2x and 8x respectively.
Total number of tickets = 80
[tex]2x+8x=80[/tex]
[tex]10x=80[/tex]
Divide both sides by 10.
[tex]x=\dfrac{80}{10}[/tex]
[tex]x=8[/tex]
Now,
Winning tickets : [tex]2(8)=16[/tex]
Losing tickets : [tex]8(8)=64[/tex]
Therefore, the winning and losing tickets are 16 and 64 respectively.

for a given input value of n, the function h outputs a value of m to satisfy the following equation.
m+1=-2(n+6)
write a formula for h (n) in terms of n
h(n)=
Answer:
h(n) = - 2n - 13
Step-by-step explanation:
Given
m + 1 = - 2( n + 6) = - 2n - 12 ( subtract 1 from both sides )
m = - 2n - 13, that is
h(n) = - 2n - 13

2. Toss 4 times Imagine tossing a fair coin 4 times . (a ) Give a probability model for this chance process . (b) Define event B as getting exactly three tails . Find P(B)
Answer:
If a coin is tossed 4 times; number of possible outcomes = (2^4) = 16. 3 heads and 1 tail can occur from 4 tosses in (4C3)*(1C1) = 4*1 = 4 ways. So, the probability = (4 / 16) = (1 / 4) = 0.25.
i didnt really understand the question but hope this helps
According to the information given, we have that:
a) A binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.b) P(B) = 0.25.For each coin, there are only two possible outcomes, either it is heads, or it is tails. The result of the flip of a coin is independent of any other flip, hence, the binomial distribution is used to solve this question.
Binomial probability distribution[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.Item a:
The coin is tossed 4 times, hence [tex]n = 4[/tex].It is a fair coin, hence equally as likely to be heads and tails, which means that [tex]p = 0.5[/tex].Hence, a binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.
Item b:
P(B) is P(X = 3), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]
Hence, P(B) = 0.25.

Can anyone help me with this algebra problem ?
Answer:
a
Step-by-step explanation:
Answer:
y=mx+b is the form in which these equations are. B represents the y intercept and M is the slope
currently to find slope we need to get y alone on the left side of the equation for all the answers:
A.y-4=3(x-2) -----> y-4=3x-6 (i also distributed) ----> y=3x-2
B. y+4=-3(x+2)----> y+4=-3x-6 -------> y=-3x-10
C. y-2=-3(x-4) --------> y-2=-3x+12 ------> y=-3x+14
D. y-4= -3( x-2) --------> y-4= -3x+6 ---------> y=-3x+10
All of these equations except A have a slope of -3 so A is already out and to find which one is valid we need to plug in the point (2, 4) for each of the equations
B. 4=-3(2)-10 ------> 4=-6-10----> 4=-16- not valid
C. 4 =-3(2)+14 -----> 4=-6+14------>4=8 not valid
D. 4=-3(2)+10 ----->4=-6+10 ------> 4=4 - Valid
Only D is correct

if the first and fifteen terms of A.P. are 8 and -48 respectively, obtain the progression
Answer:
8, 4, 0, -4, - 8, .........
Step-by-step explanation:
The n the term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and a₁₅ = - 48, then
8 + 14d = - 48 ( subtract 8 from both sides )
14d = - 56 ( divide both sides by 14 )
d = - 4
To obtain the progression subtract 4 from each term, that is
8, 4, 0, - 4, - 8, ......
Answer:
8, 4, 0, -4, -8, -12, -16, -20,...
Step-by-step explanation:
Arithmetic Progressions
The general term of an arithmetic progression (A.P.) is:
[tex]a_n=a_1+(n-1).r[/tex]
Where:
a1 = First term
an = Term number n
n = Number of the term
r = Common difference
We are given: a1=8, and a15=-48, n=15. Calculate r:
[tex]\displaystyle r=\frac{a_n-a_1}{n-1}[/tex]
[tex]\displaystyle r=\frac{-48-8}{15-1}[/tex]
[tex]\displaystyle r=\frac{-56}{14}[/tex]
r = -4
We can get the terms of the progression by subtracting 4 to the previous term.
Thus, the first terms of the progression are:
8, 4, 0, -4, -8, -12, -16, -20,...

Jordan's dog with p.M. Pounds Emmett apostrophe s dog with 25% more than Jordan star which expression represents the weight in pounds of Emmett apostrophe s dog select all the apply a 0.25 P 1.25 p c p + 0.25 DP + 120.25
Answer: 1.25 p , where p= Weight of Jordan's dog
Step-by-step explanation:
Let p = Weight of Jordan's dog .
Given: Emmett apostrophe's dog with 25% more than Jordan star.
Then, weight (in pounds) of Emmett apostrophe s dog = p +25% of p
= p +0.25 p [We divide a number by 100 to remove %]
= p(1+0.25)
= p(1.25)
=1.25 p
Hence, the expression represents the weight in pounds of Emmett apostrophe's dog=1.25 p

77th term for -10,-8,-6
9514 1404 393
Answer:
142
Step-by-step explanation:
The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...
an = a1 +d(n -1)
an = -10 +2(n -1) = 2n -12
Then the 77th term is ...
a77 = 2(77) -12 = 154 -12
a77 = 142
The 77th term is 142.

The world's future society predicts that by the year 2020, airplanes will be able to carry 1400 passengers. Today's biggest jets carry 600 passengers. What will be the percent of the increase of airplane passengers?
P.S. this is a Percent increase/decrease
from: 600
to: 1400
%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)
Answer:
133.33333333 percent
the diffrence is 800
Step-by-step explanation:
[(1400 - 600) / 600] × 100%
= 1.3333333333 × 100%
= 133.33333333%
Answer:
133.33% increase
Step-by-step explanation:
This is a percent increase, and to solve for one you need to know the following formula
[tex]|\frac{new~value~-~original~value}{original~value}| *100[/tex]
Plugging it in;
New value = 1400
Old value = 600
[tex]|\frac{new~value~-~original~value}{original~value}|= |\frac{1400-600}{600}| = |\frac{800}{600}| = 1.333333333[/tex]
1.3333333 as a percent is
133.33%
So you have an increase of 133.33%

For the linear model, y = -67.9x +679, the distance, in miles y, is a function of time, x, in hours. Use the model to calculate the total distance, in miles, at x = 2 hours.
Answer:
543.2 miles
Step-by-step explanation:
Input the given value of x into the equation and solve for y:
y = -67.9x + 679
y = -67.9(2) + 679
y = -135.8 + 679
y = 543.2
The total distance in miles after 2 hours is 543.2 miles.
How do you know whether an ecuation is an identity? How many solutions does an identity have? Explain
Choose the correct answer below
O, A. An equation is an identity w it can be rewitten as an equation of the form"variable = ruumiker, such as x=5 or y=3. Such an equation has an infinite
number of solutions because a variable can be any number
OB. An equation is an idersity it can be rewritten as an equation of the form "variable = number," such as x=5 or y=3. Such an equation has only one solution,
and the solution is called the identity of the variable
OC. An equation is an identity #it can be rewritten as 0-0. Such an equation has only one solution, 0, and that is the identity of the variable
OD. An equation is an identity if it can be rewritten as 0 =0. Such an equation has an infinite number of solutions because it reduces to a true statement
regardless of the value of the variable
Answer: D. An equation is an identity if it can be rewritten as 0 =0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.
Step-by-step explanation:
For an identity equation ; The value on the right and left hand side of the equation are equal :
Left hand side = Right hand side
The solution to an identity solution is infinite because the equation holds true for every value substituted for the variable.
Hence, for every value substituted in for the variable in the equation, the equation is a true statement.
