6,5×10¹¹/1,3×10⁸= 65/13 ×10³= 5×10³=5000
Answer:
12...10...11...13
Step-by-step explanation:
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
B convenience sampling because if it looks bad then she should throw it away but if it looks good then she should keep it
The answer is 2 hours
How I did it was that I divided 60 and 30
