Answer:
$151.87
Step-by-step explanation:
The new balance includes the previous balance, plus finance/interests charges, plus the new purchases, minus the payment(s).
So,
Previous balance: $142.55
+ Finance charge: $2.82
+ New purchases: $86.50
= Sub-total: $231.87
- Payment: $80.00
= New Balance: $151.87
It's commutative property because of the order
Answer:
The solution is (5, 3)
Step-by-step explanation:
To solve this system of linear equations, let's use elimination by addition and subtraction. This approach is particularly easy because one equation already has +y and the other -y, summing up to zero:
4x+y=23
3x-y=12
---------------
7x = 35
Then x must be 5.
Substituting 5 for x in the first equation, we get
4(5) + y = 23. Then 20 + y = 23, or y = 3.
The solution is (5, 3)
Answer: The line that can be drawn through points D and E is contained in plane Y.
Step-by-step explanation:
Hello!
You start with 13 1/4 inches of steel
You cut 2 3/4
So yo subtract these two
13 1/4 - 2 3/4 = 10 2/4
Then you cut 3 1/4 inches off
You subtract these as well
10 2/4 - 3 1/4 = 7 1/4
The answer is 7 1/4
Hope this helps!
