Answer:
x =7.62
Step-by-step explanation:
Using Pythagoras Theorem:
a² + b² = c²
7² + 3² = x²
x² = 49 + 9
x = √58 .......in radical form
x =7.62 .....in 2 decimal form
x = 7.6 ......in nearest tenth place
By solving given equations, the value of c is 30.
Given two equations
x + 2y = 10 and
3x + 6y = c
These lines represents the same line for some constant c.
Value of c:
x + 2y = 10-------------(1)
3x + 6y = c-------------(2)
Dividing equation (2) by 3

After solving the above equation, we get
x + 2y = c/3-----------(3)
Remember that a line is written as ax + by = c, in our case, both lines have a =1 and b = 2. Therefore, in orther that the two lines are equal, we need that, 10 = c/3
c = 10 × 3 = 30
c = 30
Therefore,
The value of c is 30.
