3. Find the value of x and explain your reasoning (4x - 8) (3x + 10) (11x + 2y)º
1 answer:
The question is an illustration of angles on a straight line
The value of x is 25.4
<h3>How to determine the value of x</h3>In the figure, angles 1 and 2 are angles on a straight line
Where:
- Angle 1 = 4x - 8
- Angle 2 = 3x + 10
So, we have:
Collect like terms
Divide through by 7
Hence, the value of x is 25.4

Answer:
b. Multiplying decimals less than one is finding a part of a part.
Step-by-step explanation:
A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is .
The product of a part and another part can be expressed as;
x
=
or,
x
=
or,
x
=
=
The three examples shows: a part x a part.
Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.
