How to solve 3/8=24/c+10

1 answer:

5 0

3/8=2/4c+10

Multiply all terms by c and cancel:

3c/8=24+10c

(Simplify both sides of the equation)

3/8c=10c+24

(Subtract 10c from both sides)

3/8c−10c=10c+24−10c

−77/8c=24

(Multiply both sides by 8/(-77))

(8/−77)*(−77/8c)=(8/−77)*(24)

c=−192/77

Write the explicit formula

mixas84 [53]

Answer:

The required explicit formula is A(n)= 4-4n

10th term of arithmetic sequence is (-36)

Step-by-step explanation:

Given arithmetic sequence is 8,4,0,-4,-8......

The arithmetic sequence is given by a,a+d,a+2d.......a+(n-1)d

Comparing both the sequence we get,

a=8 and a+d=4

For value of d:

d+a=4

d=4-8=(-4)

The explicit formula is given by : A(n)= a+(n-1)d

A(n)= a+(n-1)d

A(n)= 8+(n-1)(-4)

A(n)= 8-4n+4

A(n)= 4-4n

Therefore, The required explicit formula is A(n)= 4-4n

To find value of 10 th term:

Take n=10 in explicit formula

A(10)= 4-4(10)

A(10)= -36

Therefore, 10th term is (-36)

(a) Solve 7( k - 3 ) = 3k - 5

babymother [125]

A) $7(k-3)=3k-5\\ 7k-21=3k-5\\ 7k-3k=-5+21\\ 4k=16\\ k=\frac { 16 }{ 4 } \\ k=4$

b) $(2x+3)(x-8)\\ 2{ x }^{ 2 }-16x+3x-24\\ 2{ x }^{ 2 }-13x-24$

c) $\frac { 7-3f }{ 4 } =2\\ 7-3f=4\cdot 2\\ 7-3f=8\\ -3f=8-7\\ -3f=1\\ f=-\frac { 1 }{ 3 }$

Help me find the area of this please

Vlada [557]

Answer:

${215cm}^{2}$

Step by Step

first, I'll divide the big shape into 3 smaller ones. it will be the rectangle on the top (10x8), the square below that (10x10), and the triangle on the right (7x10/2)

if I calculate all, I get 80cm squared, 100cm squared, and 35cm squared.

if I add them all up, I get

80+100+35=215cm squared

If this helped, please consider picking me as Brainliest thank you!
