Divide £1200 into 5:7

Step-by-step explanation:

Let x be the pound.

The ratio is 5:7

Then,

The 1st pound be 5x

and

2nd pound be 7x

Then,

5x + 7x = £1200

12x = £1200

x = £1200/12

x = £100

Then,

The 1st pound be

5x = 5×£100 = £500

And

2nd pound be

7x = 7×£100 = £700

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

the answer would be c:   ax + b = ax + c
