Given that √((x + y)⁄(x - y)) = z, value of x when y = 4 and z = 3 is

112⁄26

150/35

26⁄112

124/56

Correct! Wrong!

A number is added to 4, result is equal to subtracting 10 from 3 times of that number number is

11

7

5

9

Correct! Wrong!

Single denominator expression for (1⁄4)c⁄(c + 1⁄3)

3c⁄(4(3c + 1))

3c⁄4

4c + 1⁄3c

4⁄3c

Correct! Wrong!

If c + 7 = x²⁄3, making x subject of formula we get

x = √(3c + 21)

x = 21c + 3

x = 3c + 21

x = 12 - 3c

Correct! Wrong!

If we make a subject of √(3a - 2) = √(a⁄b)

a = 2b

a = 5b - 1

a = 3b + 1

a = 2b⁄(3b - 1)

Correct! Wrong!

Making p, subject of formula 3b = 2p - 7, we get

p = 2⁄3b

p = 2b + 7⁄3

p = (3b + 7)⁄2

none of above

Correct! Wrong!

Solving e + e⁄2 + e⁄3 = 11 gives result

e = 10

e = 12

e=13

e = 11

Correct! Wrong!

A number when added to 5 gives same result as when 2⁄3 of it is subtracted from 6, number is

5⁄3

3⁄5

2⁄5

4⁄5

Correct! Wrong!

Simplifying given expression 7⁄(2x - 5) + 4⁄(x - 3) gives us

23x - 31

(15x - 41)⁄(2x - 5)(x - 3)

(x - 3)(2x - 5)⁄23x

none of above

Correct! Wrong!

Given that A = (1⁄3)πr² h + (4⁄3)πr³ find A when r = 7, h = 15 and π= 3.142
