Answer:
4.7
Step-by-step explanation:
5.2²+b²=7²
27.04+b²=49
b²=49-27.04
b²=21.96
b=√21.96
b=4.68614
Subtract the two numbers and you will get the answer
Answer:
Step-by-step explanation:
If u are saying 12/5, 5 goes into 12 2 times which is 10. there is 2 left so it is 2 and 2/5
Graphing the system of equations is shown in figure attached.
Solution set is (2,-4). The lines will intersect at (2,-4)
Step-by-step explanation:
We need to graph the system of equations. 
First we will find value of x and y
Let:

Add eq(1) and eq(2)

Putting value of x in eq(1) and finding y

So, y=-4
