Answer:
x = 6
Step-by-step explanation:
5 (x - 3) + 2 = 5 (2x - 8) - 3
<em>remove the parenteses</em>
5x - 15 + 2 = 10x - 40 - 3
<h3><em>calculate</em></h3>
5x - 13 = 10x - 43
<h3><em>move the terms</em></h3>
5x - 10x = -43 + 13
<h3><em>collect like terms </em></h3><h3><em>calculate</em></h3>
-5x = -30
<h3><em>divide both sides</em></h3><h3><em /></h3>
Solution
x = 6
Answer:
66.56cm = perimeter
Step-by-step explanation:
First find the easy part (the rectangle)
10+10+17+17=54
subtract the part that is not really there (dashes)
54-8=46
Add the height of the circular part
46+8=54
Find the circumference of a circle with a radius of 8
2(8)(3.14)=50.24
Divide by 4 (the circumference is only 1/4 of the the actual circle in this problem)
50.24/4=12.56
Add all of it together
12.56+54=66.56
3.6 * 10^(-3) is the scientific notation
