6. What is the sum of the solutions?

vlada-n [284]

x * x = x^2

x * .7 = .7x

-6 * x = -6x

-6 * .7 = -4.2

x^2 + .7x - 6x -4.2

x^2 - 5.3 - 4.2

x = 6

Marat540 [252]

Answer:

y=-9x-1

Step-by-step explanation:

Answer : The amount of margarine needed is 1 kg.

Step-by-step explanation :

First we have to convert volume of syrup from mL to L.

Conversion used:

1 L = 1000 mL

or, 1 mL = 0.001 L

So, 225 mL = 0.225 L

Now we have to calculate the amount of margarine needed.

As, 0.225 L of syrup needed 150 g of margarine

So, 1.8 L of syrup needed $\frac{1.5L}{0.225L}\times 150 g=1000g$ of margarine

Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)

Therefore, the amount of margarine needed is 1 kg.
