The range would be [-3, infinity)
-3 (inclusive) to infinity (non-inclusive)
Answer:
Number : 42
Step-by-step explanation:
This number will be a two - digit number, and hence we can say that it is yz. The ratio of the units digit to the tens digit is given by 1 / 2, so z / y = 1 / 2.
In addition the tens digit is 2 more than the units digit, so y = z + 2. We therefore have the following system of equations,
y = z + 2,
z / y = 1 / 2
Substituting the first equation into the second we receive z / z + 2 = 1 / 2. Using this we can solve for z.
z / z + 2 = 1 / 2 ( Cross - Multiply )
z + 2 = 2z, z = 2
And knowing z we can solve for y. y = z + 2 = 2 + 2 = 4. Therefore our number is 42.
Answer:
h = 1 2/3
Step-by-step explanation:
1/2 (5-2h) = h/2
Multiply each side by 2
(5-2h) = h
Add 2h to each side
(5-2h +2h) = h+2h
5 = 3h
Divide by 3
5/3 = 3h/3
5/3 =h
1 2/3 = h
Check
1/2 (5-2*5/3) = 5/3/2
1/2 ( 5 - 10/3) = 5/6
1/2 ( 15/3 - 10/3) = 5/6
1/2 ( 5/3) = 5/6
5/6 = 5/6
Answer:
147
Step-by-step explanation:
The other two options would be more closed and since this angle is open, it is the larger one.
