If Sally has x books that are 2 pounds then her x books weights a total of 2x lbs.
8 books of 3 lbs weights 8*3=24lbs
All them add up to 62, therefore we can conclude to the equation :
2x+24=62
or we can simplify to
2x=38
or even
x=19
Answer:
4.543 billion years
Step-by-step explanation:
Area of trapezoid = 1/2(b1+b2)h
b1 and b2 are top and bottom bases
so b1 = 15.8 and b2 = 21.8
h is height so h = 11.7
so
A = 1/2(15.8 + 21.8)(11.7)
A = 1/2(37.6)(11.7)
A = 219.96
answer
D. 219.96 yd^2
