Answer:
Step-by-step explanation:
We can solve this system just by summing each side of the equation:
So, both left sides will be sum, and both right sides too.
The resulting expression will be:
Ordering and solving both sides:
Hence, the value to the system is
It's important to combine both equation, because the exercise is asking for the solution of the system.
To get a fraction as a decimal, you have to divide the numerator by the denominator (commonly on a calculator, which is the easiest).
In this case, divide 20 by 100 to get the answer of 0.2.
So, 20/100 as a decimal is 0.2.
This question basically asks for the LCM of 3 and 5, which is 3 x 5 =15
This is the answer: 15
Check : The first rectangle had 1/3 shaded; ( one in every three parts)
So for 15 parts altogether, 5 would be shaded ( 1/3 = 5/15)
The second rectangle had 2/5 shaded ( two for every five parts)
So for 15 parts altogether, 6 would be shaded (2/5 = 6/15)
