The two equations are
P: y+z =6 and
Q: 5y +9z =1
Now to eliminate y , we have to make the coefficient of y same and with opposite sign
In equation Q , the coefficient of y is 5
So in equation P the coefficient of y should be -5
So we multiply equation P by -5
So (y + z = 6) ⋅ −5
Option second is correct
The answer is 89078.88 ft
1 mile = 5280 feet
Multiply 16.871 by the length value of 5280
16.871 * 5280 = 89078.88 ft
Answer:
114
Step-by-step explanation:
Answer:
The average change in balance each day during his time $41
Step-by-step explanation:
Here, we want to write an integer to represent the average balance change in the 30 days period.
First, let’s find difference between opening and closing balance= (1800-570) = 1230
We shall now divide this by 30 = 1230/30 = $41
