The 20 questions
-
Make x the subject of y = 3x + 4.
- x = (y - 4)/3
- x = (y + 4)/3
- x = 3y - 4
- x = y/3 - 4
-
Make r the subject of A = πr².
- r = √(A/π)
- r = πA²
- r = A/π²
- r = √(Aπ)
-
Make t the subject of v = u + at.
- t = v/(u + a)
- t = v - u + a
- t = (v - u)/a
- t = (u - v)/a
-
Make b the subject of a = 2b - 5.
- b = 2a + 5
- b = a/2 - 5
- b = (a - 5)/2
- b = (a + 5)/2
-
Make c the subject of P = a + b + c.
- c = P - a - b
- c = (P - a)/b
- c = P + a + b
- c = P/(a + b)
-
Make m the subject of F = ma.
- m = a/F
- m = F - a
- m = Fa
- m = F/a
-
Make x the subject of y = (x + 3)/2.
- x = y/2 - 3
- x = 2y - 3
- x = (y - 3)/2
- x = 2y + 3
-
Make u the subject of s = (u + v)t/2.
- u = (2s - v)/t
- u = 2s/t - v
- u = s/(2t) - v
- u = 2st - v
-
Make h the subject of V = πr²h.
- h = Vπr²
- h = V/(πr²)
- h = V/π - r²
- h = V - πr²
-
Make y the subject of 2y - 3x = 8.
- y = (8 + 3x)/2
- y = (3x - 8)/2
- y = 4 - 3x
- y = (8 - 3x)/2
-
Make e the subject of d = √(e² + f²).
- e = (d - f)²
- e = d² - f²
- e = √(d² - f²)
- e = √(d + f²)
-
A cost is C = 15 + 4h. Make h the subject.
- h = C/4 + 15
- h = 4C - 15
- h = (C - 15)/4
- h = (15 - C)/4
-
Make a the subject of T = 2(a + b).
- a = T/2 - b
- a = (T - b)/2
- a = 2T - b
- a = T/2 + b
-
Make k the subject of A = k(b + c).
- k = (A - b)/c
- k = A - b - c
- k = A/(b + c)
- k = A(b + c)
-
Make g the subject of s = ½gt².
- g = 2st²
- g = s/(2t²)
- g = √(2s/t)
- g = 2s/t²
-
Make x the subject of 4 - x = y.
- x = 4 + y
- x = 4 - y
- x = y - 4
- x = y/4
-
Make m the subject of y = mx + c.
- m = (y - c)/x
- m = (y + c)/x
- m = y - c/x
- m = (c - y)/x
-
Make x the subject of 2(x + y) = z.
- x = (z - y)/2
- x = 2z - y
- x = z/2 + y
- x = z/2 - y
-
Make d the subject of c = 3d/5.
- d = c/15
- d = 5c/3
- d = 5c + 3
- d = 3c/5
-
Make x the subject of x/a + b = c.
- x = a(c - b)
- x = a(c + b)
- x = (c - b)/a
- x = c - a - b
