10 pounds=? solution 10.43×10÷7=14.9 the equals sign means cross multiply.
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = 
x + 4 → (1)
- x + y = - 5 → (2)
Substitute y = x + 4 into (2)
- x + x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
This is the symmetric property of equality, and in a more general form it can be written as: if a=b then b=a.
This is not to be confused with communicative property, which says that the order doesn't matter in some operations, such as addition, and can be written as a+b=b+a
Area is equal to length times width, so 1.3x would represent the area. B is the answer.
