You are given that
4a-2b = 10
(a)
Write down the value of
2a - b

The value of 2a - b in the given expression is 5

From the question,

We are to write down the value of 2a - b

The given expression is 4a - 2b = 10

To determine the value of 2a - b, we will factorize the given expression and then solve for 2a - b

From the given expression,

4a - 2b = 10

Factorizing, we get

Now, divide both sides by 2

∴

Hence, the value of 2a - b is 5

2a - b = 5

Step-by-step explanation:

4a - 2b = 10

take out the highest common factor of the left side

2(2a - b) = 10

divide both sides by two

2a - b = 10/2

2a - b = 5

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
