Answer:
2/3
Step-by-step explanation:
1/3 is the same as 3/9 (multiply 3 to both numerator and denominator) 3/9+3/9 is 6/9. 6/9 can be simplified by dividing 3 to both sides to get 2/3.
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
Rectangular book
two 8 1/2 sides
two 9 1/4 sides
8 1/2*2=17
9 1/4*2=18 1/2
17+18 1/2= 35 1/2
The perimeter of the textbook is 35 1/2 inches or 35.5 inches.
Hope this helps :)
