find the sum of first 50 terms in the sequence 10n-15.
Answer:
485 bro just do it with calculator
Step-by-step explanation:
10×n-15
10×50-15
485
Answer:
12,000.
Step-by-step explanation:
First term = 10(1) - 15 = -5
50th term = 10(50) - 15 = 485
Sum of 50 terms = (50/2)(-5 + 485)
= 25 * 480
= 12,000

First person to answer this correctly gets Branilist!
Answer:
9. -1
First combine the like terms (-5x and 3x), the move -9x to the other side. That equals 7x. Then move -16 (turn positive) and add it to -23, that equals -7. Divide both sides by 7.
10. 9
Add 1 to -24. Then move -23(turn positive) to the other side. Combine with -5 and you get 18. Then move 6r and subtract it from 8r. Divide both sides by 2.
11. 11
Subtract 7a from 9a= 2a. then add 3a and 2a and move 5a to the other side. Add -5a and 2a = -3a. Divide both sides by -3.
12. 5
Combine the like terms. Move -25 and turn it positive and then add it to 20= 45. Turn -2m positive and add it to 7m. Divide both sides by 9.
13. -5
Use the distributive property on both sides. Move 2k and subtract it from 4k= 2k. Move -8 and add it to -18= -10. Divide both sides by 2.
14. -2
Use the distributive property. Move -5n and add it to -6m= -m. Move 18 and subtract it from 20= 2. Divide both sides by -1.
15. -3
Use the distributive property and combine like terms. Move 4p to the other side and subtract from -7p= -11p. Change the sign of 16 and add to 17= 33. Divide both sides by -11.
16. -13
Use the distributive property (pay attention to signs) and combine the like terms. Move -8v, turn positive, and add to -6v= 2v. Move 14, turn negative, and combine with -12= -26. Divide both sides by 2.

please show all work!
Answer:
[tex] \displaystyle - 3 \sqrt{5n} + 4 \sqrt{15} n[/tex]
Step-by-step explanation:
we would like to simplify the following expression:
[tex] \displaystyle \sqrt{15} ( - \sqrt{3n} + 4n)[/tex]
recall distribution property thus:
[tex] \displaystyle - \sqrt{3n} \sqrt{15} + 4n \sqrt{15} [/tex]
remember that,
[tex] \displaystyle \sqrt{a} \sqrt{b} = \sqrt{ab} [/tex]so assign variables:
[tex]a \implies 3n[/tex][tex]b \implies 15[/tex]simplify Multiplication:
[tex] \displaystyle - \sqrt{45n} + 4 \sqrt{15} n[/tex]
rewrite 45 as 9×5:
[tex] \displaystyle - \sqrt{9 \times 5n} + 4 \sqrt{15} n[/tex]
utilize the formula:
[tex] \displaystyle - \sqrt{9 } \sqrt{5n} + 4 \sqrt{15} n[/tex]
simplify square:
[tex] \displaystyle \boxed{- 3 \sqrt{5n} + 4 \sqrt{15} n}[/tex]
and we're done!
[tex]\boxed{\sf a(b+c)=ab+bc}[/tex]
[tex]\boxed{\sf \sqrt{p}\sqrt{q}=\sqrt{pq}}[/tex]
Solution[tex]\\ \rm\longmapsto \sqrt{15}(-\sqrt{3n}+4n)[/tex]
[tex]\\ \rm\longmapsto -\sqrt{15}\sqrt{3n}+4\sqrt{15}n[/tex]
[tex]\\ \rm\longmapsto -\sqrt{3(15)n}+4\sqrt{15}n[/tex]

Solve for X when 7cos2x = 5
Answer: x = 22.21
Step-by-step explanation:
Given
7 · cos (2x) = 5
Divide 7 on both sides
7 · cos (2x) / 7 = 5 / 7
cos (2x) = 5/7
Divide cosine on both sides (meaning applying cos⁻¹ to the right-hand side)
2x = cos⁻¹ (5/7)
Divide 2 on both sides
2x / 2 = [cos⁻¹ (5/7)] / 2
[tex]\boxed {x=22.21}[/tex] (Rounded to the hundredth place)

If f(x) = 24 +5, then what is the remainder when f(x) is divided by 2 + 2?
Answer:
The question is incorrect as it lacks the "x" component. Function f(x) cannot be stated without the x, elseways it couldn't be called "f(x)"

If R is the midpoint of OS , RS = 2x - 4, ST = 4x – 1, and RT = 8x – 43, find QS.
Answer:
56
Step-by-step explanation:
The numerical length of QS is 128.
We have a Line Segment QT and a point R lies on the midpoint of QS.
We have to determine length of QS.
What is Mid - Point of a line?The mid - point of a line is a point that divides it into two parts of equal lengths.
According to question, we have -
RS = 2x - 4
ST = 4x – 1
RT = 8x – 43
Since, R is the midpoint of QS -
QR = RS = 2x - 4
QS = QR + RS = 2 x QR = 2(2x - 4)
Now -
ST = RT - RS
ST = 8x - 43 - 2x + 4
ST = 6x - 39
and
ST = 4x - 1 [Given]
Therefore -
6x - 39 = 4x - 1
6x - 4x = - 1 + 39
2x = 38
x = 19
Now -
QS = QR + RS = 2RS
QS = 2(2x - 4) = 2( 2 x 19 - 4) = 2(38 - 4) = 2 x 34 = 128
Therefore - QS = 128
Hence, the numerical length of QS is 128.

An interger p is two-third of another and their difference is 10.find the two interferes
Answer:
30 , 20
Step-by-step explanation:
Let the other number = x
[tex]p = \dfrac{2}{3}x\\[/tex]
x - p = 10
Plugin p = (2/3)x in this equation,
[tex]x -\dfrac{2}{3}x=10\\\\\dfrac{3}{3}x-\dfrac{2}{3}x=10\\\\\dfrac{1}{3}x=10\\[/tex]
Multiply both side by 3
x = 10*3
x = 30
[tex]p=\dfrac{2}{3}*30\\\\p= 2 * 10[/tex]
p = 20
Answer:
30 and 20
Step-by-step explanation:
We have an integer p and another [tex]\frac{2}{3}[/tex] p , their difference is 10 , so
p - [tex]\frac{2}{3}[/tex] p = 10 ( multiply through by 3 to clear the fraction )
3p - 2p = 30 , that is
p = 30
and [tex]\frac{2}{3}[/tex] × 30 = 2 × 10 = 20
The 2 integers are 30 and 20
