Answer:
101.76
Step-by-step explanation:
(12.9−3.1)(6.2)−2+43
=(9.8)(6.2)−2+43
=60.76−2+43
=58.76+43
=101.76
Answer:
The solution to the system of linear equations is (1,9).
Step-by-step explanation:
The given system of linear equations
... (1)
.... (2)
Subtract equation (2) from equation (1) to eliminate y.
On combining like terms, we get
Add 8 on both sides.

Divide both sides by 8.

The value of x is 1.
Substitute x=1 in equation (1).



The value of y is 9.
Therefore the solution to the system of linear equations is (1,9).
Answer:
8

Answer:
Expression: p = 320 x 1.2
Your price: $384
Step-by-step explanation:
Finding 20% is the same as multiplying that number by 0.2 adding it on to the original number. This can also be represented as multiplying by 1.2.
This means the expression is p = 320 x 1.2, where p is the new price.
This gives you $384.
