Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question.
5 x 6 = 30, 30 + 8 =...
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
2a+5a+9a = 16a
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
To evaluate (5a + 5b) where (a = -6) and (b = -5), substitute the values into the expression: [ 5(-6) + 5(-5) = -30 - 25 = -55. ] Therefore, (5a + 5b = -55).
The statement is false. 5a +6 = 5a + 30 Subtract 5a from both sides: 6 = 30 and that is plain and simple rubbish!
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
5 x 6 = 30, 30 + 8 =...
30-5a = 25
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
5a
2a + 5a + 3a = 10a
2a+5a+9a = 16a
5a + 20 = ? Your question is incomplete.
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
a + 3a + 5a = 180 9a =180 a = 20
