What is -7a plus 2a plus 9 equals 24?
-7a+2a+9 is also -5a+9. -5a+9=24. -5a=15. a=-3.
What is 5a3-45a equals -2a2 plus 18?
5a3-45a=-2a2+18 5a(a2-9)=-2(a2-9) 5a=-2 a=-2/5
What is the value of a in 13a - 6 plus a equals 5a plus 3 plus 3a?
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
Does the a in both what expressions 3a - 9 equals 6 and 5a plus 2 equals 27 have the same value?
Yes.
How do you work out 5a plus 7 equals 9?
How do you work out 5a plus 7 equals 9? Put in equation form5a+7=9 subtract 7 from both sides gives you 5a=2divide 5 from both sides gives you a=2/5 or .4substitute in .4 for your a to check answer5(.4)+7=9
What is a in the equation 5a-20 plus 2a equals 6a-11?
5a-20+2a = 6a-11 5a+2a-6a = 20-11 1a = 9 a = 9
Given that a is the root of each of the equations xsquare-5x plus k equals 0 and xsquare-6x plus 3k equals 0 where k is not equal to 0 find k and a?
Since a is the root of both equations, a satisfies them:a2 - 5a + k = 0a2 - 6a + 3k = 0The right hand side of both the equations are same. Therefore,a2 - 5a + k = a2 - 6a + 3k6a - 5a = 3k - ka = 2kk = (a/2)Substituting k = a/2 in one of the equations,a2 - 5a + (a/2) = 0Solving, a=9/2k=a/2=9/4Thus 'a' = (9/2) and 'k' = (9/4).
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 9 plus 7 equals 96 9 plus 7 equals what?
96
2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 Then 9 plus 7 equals?
If I am correct, 9 plus 7 equals 112.
A plus 3a plus 5a equals 180?
Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20
How do you factor 3a2-16a plus 5?
3a2 - 16a + 5 = 3a2 - 15a - a + 5 = 3a(a -5) - 1(a -5) = (3a - 1)(a - 5)
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 and 8 plus 4 equals 96 then 9 plus 7 equals?
144 9+7 = 16 and 9*16 = 144
