What is the answer i'll give brainly

egoroff_w [7]

Answer:

c = -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

$4(-2)=4*\frac{-c-11}{4}$

Cancel multiplied terms that are in the denominator

$4(-2)=-c-11$

Multiply the numbers

$-8=-c-11$

Add 11 to both sides of the equation

$-8+11=-c-11+11$

Simplify

$3=-c$

Divide both sides of the equation by the same term

$\frac{3}{-1}=\frac{-c}{-1}$

Simplify

$c=-3$

I’ve saved £264. I will spend 3/12 of this. How much do I have left?

lara [203]

Hi there! The answer is £198.

If you spend 3 / 12 of a certain amount of money, you have 9 / 12 of the money left.

Simplify the fraction.
9 / 12 = 3 / 4.

To find the amount of money left, we multiply this factor by 264. We get the following
£264 × 3/4 = £264 × 0.75 = £198

Therefore the answer is £198
