Answer:
x = 5/4
Step-by-step explanation:
x-3=2-3x
Add 3x to each side
x+3x-3=2-3x+3x
4x-3 = 2
Add 3 to each side
4x-3+3 = 2+3
4x =5
Divide each side by 4
4x/4 = 5/4
x = 5/4
Answer:
5/4
Step-by-step explanation:
[tex]x-3=2-3x\\-3=2-4x\\-5=-4x\\\frac{-5}{-4} =x\\x=\frac{5}{4}[/tex]
Combine all like terms by moving them to their respective sides, then simplify as best you can.
How do you write 7,700,000 in scientific notation?
Answer:
7.7 × [tex]10^{6}[/tex]
Step-by-step explanation:
Start off with finding the digits in this case it would be 7,700,000
Now insert a decimal so that it is a number under 10.
That would be 7.7
to figure out what the exponent would be you have to count how many "jumps" the decimal takes to get back to the original number.
It would take 6 "jumps" to end up back to 7,700,000
Now that we have that information we can make the scientific notation
1) Take the number (7.7)
2) Multiply the number by 10 with the exponent of "jumps"
Thus,
7.7 × [tex]10^{6}[/tex]

How to factorise n(2n+1)(n+1)+n(2n+1)? I know the answer is n(2n+1)(n+2) but can someone explain every step fully, thanks:)
we have n(2n+1)(n+1) +n(2n+1) = n(2n+1)(n+1)+n(2n+1).1
= n(2n+1)(n+1 +1) = n(2n+1)(n+2)
P/s: sorry i don't know how to explain but i can give you some example so you can understand the question easily

Step-by-step explanation:
A study investigated the job satisfaction of teachers allowed to choose supplementary curriculum for their classes versus teachers who were assigned all curricular resources for use in their classes. On average, when surveyed regarding job satisfaction, teachers give a score of 3. 3 out of 5 with a standard deviation of 0. 6. When the authors of the study interviewed 40 teachers who supplemented with their own materials, they found 3. 5 to be the mean. The authors wanted to know if the group of teachers that could choose supplementary curriculum had a higher level of job satisfaction. They used a significance level of 1%. Which of the following statements is valid based on the results of the test? The data shows that teachers allowed to choose supplementary curriculum for classes are more satisfied with their jobs. The data shows that teachers who were assigned all curricular resources for classes are more satisfied with their jobs. The data shows that there is no difference in job satisfaction between the two groups of teachers. The data shows that the authors cannot make a determination either way with this data.

1. double a number increased by one is seventeen
2. Three less than a number is twelve
3. Triple a number is the same as double the number increased by five
4. Double a number increased by two is the same as the sum of the number and eight
Answer:
1) 2n + 1 = 17
2) n - 3 = 12
3) 3n = 2n + 5
4) 2n + 2 = n + 8
Step-by-step explanation:
Use "n" to represent the unknown number.
For question one:
we double the number → 2n
then we increase (add) by one → + 1
is (equal) to seventeen → = 17
For question two:
three less (minus) than a number is (equals) twelve → n - 3 = 12
Question three:
triple (times 3) a number is the same (equal) as double (times 2) the number increased (add) by five → 3n = 2n + 5
Question four:
double (times two) a number increased (add) by two is (equals) the same as the sum (add) of the number and eight → 2n + 2 = n + 8

Find values of x and y
Answer:
x=15
y= 21
Step-by-step explanation:
6x-11+x+5+81=180
6x+x+86-11=180
7x+75=180
-75. -75
7x=105
--- ----
7. 7
x=15
substitute the x value we just got into the following equation to find y
4y-18+y+14+6x-11=180
4y-18+y+14+6(15)-11=180
4y+y+14+79-18=180
5y+75=180

Is not a Function – { ( 3, 4 ),( 5, 2 ),( 5, 6 ),( 7, 3 ) }
Answer:
1. Yes, is a function {(2, 2),(4, 4),(6, 6),(8, 8)}
2. Yes, is a function {(0, 3),(3, 5),(5, 6),(8, 4)}
3. Yes, is a function {(1, 2),(3, 3),(4, 8),(6, 3)}
4. No, not a function {(3, 4),(5, 2),(5, 6),(7, 3)}
Step-by-step explanation:
1. Since there is one value of y for every value of x in {(2, 2),(4, 4),(6, 6),(8, 8)} , this relation is a function.
2. Since there is one value of y for every value of x in {(0, 3),(3, 5),(5, 6),(8, 4)}, this relation is a function.
3. Since there is one value of y for every value of x in {(1, 2),(3, 3),(4, 8),(6, 3)}, this relation is a function.
4. Since x=5 produces y=2 and y=6, the relation {(3, 4),(5, 2),(5, 6),(7, 3)}, is not a function.

The width of a rectangle is 5 cm more than twice the length the perimeter is 56 cm find the dimensions of the rectangle
Answer: W = 20 1/3, L = 7 2/3 cm
Step-by-step explanation:
Width, W, is 5 cm more than twice the length of the perimeter.
Perimeter = 2W + 2L
W = 2L+5
Perimeter is 56cm:
56 cm = 2W + 2L
Substitute W = 2L + 5 for W:
56 cm = 2W + 2L
56 cm = 2(2L+5) + 2L
56 cm = 4L + 10 + 2L
6L = 46 cm
L = 7 2/3 cm
Since W = 2L + 5
W = 2(7 2/3) + 5
W = 2 (23/3) + 5
W = 46/3 + 5
W = 15 1/3 + 5
W = 20 1/3
2W + 2L = P?
2(20 1/3) + 2(7 2/3) =56 ?
40 2/3 + 15 1/3 = 56?
56 = 56 YES
Which is the reciprocal of 1 6/7
Answer:
7/13
Step-by-step explanation:
You would first have to turn the fraction into an improper fraction to find the reciprocal of the fraction!
1 6/7 = 13/7
Reciprocal means reverse, so reverse the improper fraction of 13/7 to get 7/13!
