You are decorating your bedroom. To get the paint colour you want, you mix 2 parts red with 3 parts cream and 1 part blue.How much cream and blue paint will you need to mix with 4 litres of red?

Answers

Answer 1
Answer:

Answer:

6 liters of cream.

2 liters of blue.

Step-by-step explanation:

We are given that  To get the paint colour you want, you mix 2 parts red with 3 parts cream and 1 part blue.

Ratio is  2:3:1

Now we are given that we need to calculate how  much cream and blue paint will you need to mix with 4 litres of red

Since we are mixing 2 parts of red and we have 4 litres

⇒2 times 2 = 4 litres

So, since they mix 3 parts of cream

Thus 3*2= 6 lites

So they use 6 liters of cream.

Since they mix 1 parts of blue

Thus 1*2= 2 liters

So, they use 2 liters of blue.
Answer 2
Answer: The cream paint is 3/2 of the red, since there are three parts cream for every two parts red.  Similarly, the blue paint is 1/2 of the red.  Thus, there are 3/2*4=6 liters cream paint and 1/2*4=2 liters blue paint.

Solve each of the following linear systems by eliminating

Answers

3x + y = 12 (multiply whole equation by 3)
x - 3y = 24

9x + 3y = 36
x - 3y = 24
10x = 60
x = 60 / 10
x = 6
puting the x value in 1st equation
3 (6) + y = 12
18 + y = 12
y = 12 - 18
y = -6

Answer x = 6
              y = -6

What do 20-(12+6) equal

Answers

Answer:

2

Step-by-step explanation:

Since the 12 + 6 are parenthesis, we do these first

12 + 6 = 18

Then will solve the rest, 20 - 18

20 - 18 = 2, therefore leaving us with the answer of 2

0 ≤ x ≤ 20
−10 ≤ x ≤ 30
x ≥ 0
All real numbers

Answers

Answer: The first interval:0 ≤ x ≤ 20

Procedure

You have to solve this inequality

-2x^2 +40x +600 ≥ 600

-2x^2 +40x  ≥ 0

-x^2+20x ≥ 0

x^2 - 20 x ≤ 0

x(x-20) ≤ 0

That is only possible if the two factors have different signs.

Let's examine the possibilities

       x ≥ 0 and x -20 ≤ 0⇔x≤20, that is 0≤x≤20

The other possibility is

       x ≤ 0 and x - 20 ≥ 0 ⇔x≥20. This conditions is not possible.

So the solution is 0≤x≤20

meters for the dining room, and the rest for the kitchen. How many meters did she use for the
curtain in the kitchen?

Answers

Given parameters:

Total length of curtains bought = 20m

She used 8m for the living room

She used 7m for the dining room

unknown:

Quantity used for the kitchen = ?

Solution:

Quantity used for the kitchen = Total length - (living room + dining room)

Input the parameters given solve;

   Quantity used for the kitchen = 20 - (8 + 7) = 5m

The length of curtain used for the kitchen is 5m
