Subtract a1 from the term:

53-5 = 48

Divide 48 by the difference:

48/6 = 8

53 is the 8th term after the first one a1, so 53 would be the 9th term.

The answer is B. 9th term

Big dig diamond company pulverizes 152 tons of rock for every 2 ounces of diamonds it finds. how many tons of rock must it grind

vredina [299]

For this case what we can do is the following rule of three:
152 -----> 2
x --------> 20
We clear the value of x:
x = (20/2) * (152)
x = 1520 tons
Answer:
in order to locate 20 ounces of diamonds the company needs:
x = 1520 tons of rock

In parallelogram ABCD , diagonals AC¯¯¯¯¯ and BD¯¯¯¯¯ intersect at point E, AE = 3x - 5, and CE = x + 11.

german

Answer:

Step-by-step explanation:

For the case of a parallelogram, when the diagonals ( in our case AC & BD) are intersected, they are basically bisected ( divided into two equal halves ). Therefore when the diagonals intersect at point E, we can say that the diagonal AC is divided in two equal halves which in our case are AE and CE. since AE and CE are equal , we can say that,

$AE= CE \\or\\3x-5 = x+11 ---- (1)\\now solving (1) for x, \\3x-x=11+5\\2x=16\\x=8-----> (2)\\\\as \\ AC = AE+CE\\AC = 3x-5+x+11\\AC = 4x+6\\\\\\from (2)\\\\\\AC= 4(8)+6\\AC = 32+6\\AC = 38\\\\since AC = BD ( Diagonals are of same Length )\\therefore \\BD =38$
