The solutions of the equations for x are given as follows:
a. x = 36.
b. x = 15.
<h3>What is the solution for item a?</h3>
The equation for item a is given by:
x/3 - 5 = 7
Isolating x, we have that:
x/3 = 12
x = 3 x 12
x = 36.
<h3>What is the solution for item b?</h3>
The equation for item b is given by:
x/2 - 5 = 2.5
Isolating x, we have that:
x/2 = 7.5
x = 7.5 x 2
x = 15.
Hence the solutions are:
a. x = 36.
b. x = 15.

Step-by-step explanation: it's absorbed and emitted back toward Earth's surface.
Answer: 4x^2−4x+1
Step-by-step explanation:
(2x-1)^2
Square of Difference: (a−b)^2=a^2−2ab+b^2.
(2x)^2−2*2x+1
Multiplication Distributive Property: (xy)^a=
2^2x^2−2*2x+1
4x^2−2*2x+1
4x^2−4x+1

Answer: 
Step-by-step explanation: Given expression
.
In order to find the product of given expression, we need to convert 5,600,000 into scientific notation, because other number is also in scientific notation.
5,600,000 = 5.6 × 10^6.
Therefore,
.
Now, multiplying 5.63 × 5.6 first, we get 31.528.
And 10^5 × 10^6 = 10^11.
Therefore,
.
<h3>Or 3.1528 × 10^12.</h3>

In the given figure, the angles 5 and 6 form Vertical opposite angle pair.
so, correct choice is Vertical
