Answer:
3.6
Step-by-step explanation:
We must first clarify how a number is rounded.
To round a number to unity we have to look at the first number after the comma.
If this number is less than 5 (1, 2, 3, 4) we should not do anything, but if that number is 5 or greater (5, 6, 7, 8, 9) we must add a unit to the number.
That is to say:
<5 do nothing
=> 5 round to the next number (+1)
So in the case of 3.55 it would be.
3.55 = 3.6
Answer:
x – 2(x2 + 4x – 12)
Step-by-step explanation:
x – 2(x2 + 4x – 12)x – 2(x2 + 4x – 12)
Answer:
B. 10 E. 20 C. 60
Step-by-step explanation:
s = 2f
t = 2(f + s)
(15 + 15 + 30 + f + s + t)/6 = 25 This equation and the equations above show how the variables relate to each other
f = 10 The first number is 10
s = 2(10)=20 The second number is 20
t = 2(10 + 20) = 60 The third number is 60

1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
Answer:
X = - 5
Step-by-step explanation:
The above word problem is mathematically interpreted thus:
-1X - 4X = -4 - 4X + 4 + 5
-5X = - 4 - 4X + 4 + 5
-5X = - 4 - 4X + 9
Collect like terms
-5X + 4X = - 4+ 9
-X = 5
X = - 5
