-8 + b = 4 add 8 to both sides: b = 12
Evaluate -4(a+b) - 10a/b when a=8 and b=5
in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b
3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b
3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
WOuldn't it be 4b-8
Addition is commutative. That is, a + b = b + a for all a, b
A=8 B=4 C=14 Yes, I know I'm a genius. Mak - the all knowing one. MWAHAHAH!
a = 11 and b = 5.
(b + 4)(b + 4)
5b = 8 therefore b = 8/5 therefore b = 1.6
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
5b = 8 b = 8/5 or 1.6
Set it up like this: B+9=8+6B+9=14B=5
It is the commutative property of addition : A+B = B+AMultiplication has the same property, whereas in subtraction and division the order of the terms changes the result.
b = -8
b = -6
