In this problem, we are asked to declare statements that describe the orders given as stated. In the first command, we are to define the element number of the element specified, which by, in this case, is oxygen. This is expressed: Element number = 8. Then we name the element that is element = oxygen. The third command specifies the atomic weight of the elementoxygen = 15.9994. For the last command, the expression is atomic weight = oxygen. It is important to arrange the commands in order so that the program that understands the data executes the orders well and translate them into output.
Your points are (1.5,0) and (0,3.5)
The equation for slope-intercept is y2-y1 over x2-x1
3.5-0 over 0-1.5
3.5 over -1.5
Answer:
40 60 40 60 40 60 40 60 40
1. 2. 3. 4. 5. 6. 7. 8. 9.
so the answer is 9 hours
X=number of books that cost 0.60
y=number of books that cost 0.75
x+y=16
0.6x+0.75y=10.95
solve
multiply second equation by 10 for nicity
6x+7.5y=109.5
multiply first equesiotn by -6 and add to second
-6x-6y=-96
<u>6x+7.5y=109.5 +</u>
0x+1.5y=13.5
1.5y=13.5
divide both sides by 1.5
y=9
sub back
x+y=16
x+9=16
minus 6
x=7
seven 0.60 books and nine 0.75 books
