(x-1)/5 = (4x + 2)/35

lets start off by multiplying each side by 5

(x-1) = 5(4x + 2)/35

then let's multiply both sides by 35

35(x-1) = 5(4x + 2)

now let's distribute the coefficients (5 and 35) into everything in the brackets

35 times x is 35x
35 rimes 1 is 35

5 times 4x is 20x
5 times 2 is 10

(35x - 35) = (20x + 10)

we can add 35 to both sides

35x = 20x + 45

then subtract 20x on both sides

15x = 45

then divide both sides by 15

x = 3

What is the first term, common difference, and 16th term
strojnjashka [21]

Answer:

The 1st term is -67

Step-by-step explanation:

I. When Sn = \frac{n}{2}(a_{1} +  a_{n})

   If  Sn = 124, n = 8 and a_{n} = 98

                124 = 8/2(a + 98)

                124 = 4(a + 98)

                124 = 4a + 392

                124 - 392 = 4a

                -268/4 = a

                -67 = a_{1}

Hope that help :D

V=lw*h/3

So since its a square l and w are the same

11*11 = 121

h=20

20/3=  6.6666666


V=121*6.6666666

V= 806.66667
