Answer:
3
Step-by-step explan
1 x 4/2 + 1
4/2 + 1
4 divide by 2 is = 2
2+1 = 3
so the value of 1 x b/2 + 1 is = to 3

Answer:
The proposition is true.
Step-by-step explanation:
Now we proceed to demostrate that expression given is true by algebraic means:
1)
Given
2)

3)
Distributive property/
4)
Commutative, associative and modulative properties/Existence of additive inverse/
5)
Commutative property/Definition of division
6)

7)
Distributive property/Associative property/
8)
Modulative property/Existence of additive inverse/
9)
Distributive property
10)

11)
Commutative property/Definition of division/Result
A) x * y = 48
B) x -y = 8
A) x = 48/y then substituting this into B)
B) 48/y -y = 8
B) 48 -y^2 = 8y
B) y^2 + 8y - 48 =0
x = 4 y = 12
12*4 = 48
12 -4 = 8
Answer:
Step-by-step explanation:
We have two sides; the Adjacent and the Hypotnuse
Meaning we will use Cos
Cos = A/H
Cos X = 16/19
Use the inverse of Cos to find the angle
X = cos-1 (16/19)
X = 0.45499141546
X = 0.45
