Answer 1

Form equation for the statement "Subtract 5 times the number x from 8 to get 12". *

2 points

8 - 5x = 12

5x - 8 = 12

5x - 12 = 8

None of these

Ans. 8 - 5x = 12

Is m = 8, the solution of equation 2m - 5 = 11 *

2 points

2m - 5 = 11

2×8-5=11

16-5=11

11=11

LHS=RHS

Yes✓

No

Set an equation for " In an isosceles triangle, the vertex angle is thrice either base angle". ( Suppose the base angle be t in degrees). *

2 points

5t = 180

3t = 180

6t = 180

None of these

5t=180

The solution of equation : 4p - 7 = 9 *

2 points

p = 0

p = -3

p = 3

p = 4✓

Ans.

4p - 7 = 9

4p = 9+7

4p=16

p=16/4

p=4

Solve : -2(y + 3) = 8 *

2 points

y = 7

y = -7✓

y = -8

None of these

Ans.

-2(y + 3) = 8

y+3=8/-2

y+3=-4

y=-4-3

y=-7

Set the equation for the statement " You get 6, when you subtract 2 from one-fifth of a number q" and solve the equation. *

2 points

q = 60

q = 30

q = 50

q = 40✓

Ans

Let the number be q

According to the question

$\frac{q}{5} - 2 = 6 \\ q - 10 = 30 \\ q = 30 + 10 \\ q = 40$

w = 3 is the solution of which equation? *

2 points

-5 + 3( w - 4) = 18

7 - 3(5 + w) = -17✓

-4 + (7 - w) = 1

None of these

Ans

7 - 3(5 + w) = -17

7 - 3(5 + 3) = -17

7-24=-17

-17=-17

7 - 3(5 + w) = -17 is correct

Solve the equation: z/5 = 2/15 [z/5 means z upon 5, 2/15 means 2 upon 15] *

2 points

2/5

2/3✓

2

None of these

Ans

$\frac{z}{5} = \frac{2}{15 } \\ 15z = 10 \\ z = \frac{10}{15 } \\ z = \frac{2}{3}$
