a + b = 60 (1)
b < a with 6 ⇒ b = a - 6 (2)
(1), (2) ⇒ a + a - 6 = 60 ⇒ a + a = 60 + 6 ⇒ 2a = 66 ⇒ a + 66:2 ⇒
⇒ a = 33 (3)
(2), (3) ⇒ b = 33 - 6 ⇒ b = 27
So, the numbers are : a = 33, b = 27
That expression can’t be simplified and the answer is unknown. Finding what 3x+4y is impossible unless more information is provided.
Answer:
x = -39
Step-by-step explanation:
The only thing we need to do here is isolate x by subtracting 27 from both sides :)
x = -39
Note that
10² = 100
0.08² = 0.0064
and
101.6064 = 100 + 1.6 + 0.0064
It also happens that
1.6 = 2 • 10 • 0.08
which means
101.6064 = 100 + 1.6 + 0.0064
101.6064 = 10² + 2 • 10 • 0.08 + 0.08²
101.6064 = (10 + 0.08)²
101.6064 = 10.08²
which means
√101.6064 = 10.08
which, to one decimal place, is approximately 10.1.
I think your ok. thats enough info
