Answer:
C. 4(a + b + 2)
Step-by-step explanation:
2(2a + b) 8 equals 4a + 2b + 8. 4(a + b + 2) equals 4a + 4b + 8
Answer:
0.13774 inches ( approx ).
Step-by-step explanation:
Given,
The age of earth = 4.6 billion years = 4600000000 years,
The represented age of earth = 63,360 inches,
That is, scale factor in representation of age
Now, the age of human civilization = 10000 years,
Thus, the represented age of human civilization = actual age × scale factor
Let the total amount earned at a given time be y, if x is the number of hours worked and amount earned per hour is $9, thus the equation representing this information will be:
Total amount earned=(number of hours)*(amount earned per hour)
hence:
y=9*x
y=9x
Answer y=9x
Answer:
hi if you want to solve fore x and y there must be 2 equations .
Step-by-step explanation:
so that you could solve them simultaneously
-7x + 2y = 4
here 2y - 4 = 7x
( 2y -4)/7 = x
