Keep doing each step manually, and see where it slips up: −7.9+8.2−3.4+2.1=−1 −7.9+8.2+(−3.4)+2.1=−1 −7.9+(−3.4)+8.2+2.1=−1 (−7.9+(−3.4))+(8.2+2.1)=−1 −11.3+10.3=−1

Help please last question I swear
SOVA2 [1]
Jones has 3/4 total fertilizer. He wants to use 1/8 each scoop to use all of the fertilizer.
We need to make these into proportions to understand the amount of each fraction easier. 1/8 = 0.125, and 3/4 = 0.750
To do this the quick way, divide 0.750 by 0.125
0.750/0.125 = 6.
He will have to use the measuring cup 6 times.
Hope this helps!

The nth term of a sequence is 2n - 6
Serjik [45]

Answer:

Step-by-step explanation:

2n - 6

a) n = 1 ;   2n - 6 = 2*1 - 6  = 2 - 6 = -4

  n = 2 ;   2n - 6 = 2*2 - 6 = 4 - 6 = -2

  n = 3 ;   2n - 6 = 2*3 - 6 = 6 - 6 = 0

b) n=10;  2n - 6 = 2*10 - 6 = 20 - 6 = 14
