Find the value of n that satisfies 2(n+1)! + 6n! = 3(n+1), where $n! = n\cdot (n-1)\cdot (n-2) \cdots 2\cdot 1$.
Answers
Answer:
[tex]n = 5[/tex]
Step-by-step explanation:
Given
[tex]2(n+1)! + 6n! = 3(n+1)![/tex]
Required
Find n
Simplify (n + 1)!
[tex]2(n+1)*n! + 6n! = 3(n+1)*n![/tex]
Factorize
[tex]n![2(n+1) + 6] = 3(n+1)*n![/tex]
Divide both sides by n!
[tex]2(n+1) + 6 = 3(n+1)[/tex]
Open brackets
[tex]2n + 2 + 6 = 3n + 3[/tex]
[tex]2n + 8 = 3n + 3[/tex]
Collect like terms
[tex]2n - 3n = 3 -8[/tex]
[tex]-n =-5[/tex]
Multiply both sides by -1
[tex]n = 5[/tex]

Justin has a savings account.
• He started with $70 in his account.
• He deposits $15 into the account each week.
What is the total amount Justin will have in his account after 10 weeks?
Answers
Answer:
220
Step-by-step explanation:
Multiply 15 times 10 =150
150+70=220
Hope this helps :)
==========================================================
Explanation:
After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars
If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.
someone help me solve this please and with the steps :)?

Find the gradient of the line passing through the points (4a,-a) and (6a,5a)
Answers
Answer:
The gradient of the line passing through the points (4·a, -a) and (6·a, 5·a) is 3
Step-by-step explanation:
The gradient of a (straight) line given the 'x' and 'y' coordinates of two points on the line, (x₁, y₁), and (x₂, y₂) can be found using the following formula;
[tex]The \ gradient \ of \ a \ line, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The coordinates of two points on the given line are;
(4·a, -a), and (6·a, 5·a)
Therefore, we get;
[tex]The \ gradient \ of \ the \ line =\dfrac{5\cdot a-(-a)}{6 \cdot a-4 \cdot a} = \dfrac{6\cdot a}{2 \cdot a} = 3[/tex]
The gradient of the line = 3.

15 similar blouses and 2 similar skirts cost $505. 5 such blouses and 2 such
skirts cost $215. How much do 5 such blouses cost? need this ans asap!
Answers
Answer:
Cost of five blouses = $145
Step-by-step explanation:
Let
x = cost of blouse
y = cost of skirt
15x + 2y = 505 (1)
5x + 2y = 215 (2)
Subtract (2) from (1) to eliminate y
15x - 5x = 505 - 215
10x = 290
x = 290/10
x = 29
Substitute x = 29 into (2)
5x + 2y = 215 (2)
5(29) + 2y = 215
145 + 2y = 215
2y = 215 - 145
2y = 70
y = 70/2
y = 35
x = cost of blouse = $29
y = cost of skirt = $35
How much do 5 such blouses cost?
cost of a blouse = $29
Cost of five blouses = $29 × 5
= $145
Cost of five blouses = $145

Em um campeonato de futesal igor cobrou 20nfaltas das quais 65% foram convertidos em gol quantos gols de falta ele marcou nesse camponato
Answers
Responder:
13 gols
Explicação passo a passo:
Dado que :
Taxa de conversão = 65%
Número de fotos tiradas = 20
O número estimado de gols marcados será:
O produto da taxa de conversão e o número de fotos tiradas;
Número de fotos tiradas * taxa de conversão
20 * 65%
20 * 0,65
= 13 gols
Portanto, número estimado de gols marcados = 13 gols

given a is equal to 60 degree and 30 degree prove that sin a + b is equal to sin a cos b + cos a sin b
Answers
Answer:
A = 60 and B = 30
Now, A + B = 60 + 30 = 90
Also, A – B = 60 – 30 = 30
sin (A + B) = sin 90 = 1
sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30
