Answer:
I'm not sure if it's right but I got -2455.15
Step-by-step explanation:
You would use PEMDAS,
( 129 + 19 ) = 148
-18 ( 148 ) = -2664
3/2.25 = 1.333333333
1.333333333 - 2664 = -2662.666667
0.9 ( -2662.666667 ) = -2396.4
-47/8 = -58.75
-2396.4 - 58.75 = <u>-2455.15</u>
7(x + 3 ) = 6 - (-7x - 15)
Apply the distributive rule to remove parentheses.
7x + 21 = 6 + 7x + 15
Right away, you should be able to see that 7x will be cancelled rendering this equation to have no solution.
Answer: NO SOLUTION
To find the greatest common factor, first find the largest evenly divisible number that you can take out in both numbers, in this case 15 and 25. Then find the greatest or highest number of each variable that you can evenly take out or divide in both terms, this is for a, b and c.
So GCF of 15 and 25 would be 5
GCF of a = a^1 or a
GCF of b = b^1 or b
GCF of c = c^1 or c
Put everything together to find the GCF.
GCF = 5abc.
