What is the value of B after the equation A=3/7(B-25)

1 answer:

7 0

If your equation is A = 3(B-25)/7, then we can solve for B by isolating B on one side. We can do this by the following...

First, multiply both sides by 7
7A = 3(B-25)

Next, divide both sides by 3.
7A/3 = B - 25

Finally, add 25 to both sides.
7A/3 + 25 = B

Therefore, B = 25 + 7A/3

Answer:

see explanation

Step-by-step explanation:

To determine which ordered pairs are solutions to the equation

Substitute the x and y values into the left side of the equation and if equal to the right side then they are a solution.

(- 1, - 6)

3(- 1) - 4(- 6) = - 3 + 24 = 21 = right side ← thus a solution

(- 3, 3)

3(- 3) - 4(3) = - 9 - 12 = - 21 ≠ 21 ← not a solution

(11, 3)

3(11) - 4(3) = 33 - 12 = 21 = right side ← thus a solution

(7, 0)

3(7) - 4(0) = 21 - 0 = 21 = right side ← thus a solution

The ordered pairs (- 1, - 6), (11, 3), (7, 0) are solutions to the equation

Find the midpoint of A and B where A has coordinates (2, 4)<br> and B has coordinates (-3, -9).

tatuchka [14]

Answer:

(-0.5,-2.5)

Step-by-step explanation:

(x1 + x2) / 2 = x midpoint
(y1 + y2) / 2 = y midpoint

⇒ 2 + -3 = 5

⇒ 5 / 2 = -0.5

⇒ 4 + -9 = -5

⇒ -5 / 2 = -2.5

→ = (-0.5, -2.5)
