-5b = 55 To get b by itself, divide both sides by -5. (-5b)/(-5) = (55)/(-5) -5 / -5 = 1, 55 / -5 = -11 1(b) = -11 b = -11
a + c - b = 3 + 2 - 5 = 5 - 5 = 0
a = 11 and b = 5.
Evaluate -4(a+b) - 10a/b when a=8 and b=5
(11, 5)
-5b = 55 To get b by itself, divide both sides by -5. (-5b)/(-5) = (55)/(-5) -5 / -5 = 1, 55 / -5 = -11 1(b) = -11 b = -11
P = 5 A = 6 B = 11 Or.... P = 1 A = 30 B = 55
the answer is a
a + c - b = 3 + 2 - 5 = 5 - 5 = 0
a = 11 and b = 5.
a+b+2+3=5+a+b
Evaluate -4(a+b) - 10a/b when a=8 and b=5
(11, 5)
37
4+5=9
b2 + b = 30b = 5
3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b
