Step-by-step explanation:
7x+22=2(5x+2)
7x+22=10x+4 (-7x)
3x+4=22 (-4)
3X=18 (divide by 3)
X=6 pencils
check if the number is correct
asha= 7*6=42 42+22 is 64
Lucy= 5*6=30 30+2 is 3264/32 is 2
asha= 7*6=42 42+22 is 64Lucy= 5*6=30 30+2 is 3264/32 is 2there fore asha sells twice as many as Lucy
1/40 in 30 mins = 2/40 in 1 hour
2/40= 0.05 miles per hour
Answer: The approximate absentee rate that day would be 8.09%.
Step-by-step explanation:
Since we have given that
Number of students who were absent = 36
Total number of students = 445
We need to find the approximate absentee rate that day :
Rate of absentee of that day would be
Hence, the approximate absentee rate that day would be 8.09%.
It only has two number sentences because 81 divided by anything else wont work only 9 would. Also since 9 times 9 is equal to 81
12h-9h=3h move everything else to other side
3h=20-40+6
3h=-14
divide by 3
h=-14/3
