Answer:
The correct answer is distributive postulate.
Step-by-step explanation:
Look at the expression we have given:
3x + 3 = 3(x + 1)
And we are asked that which postulate is illustrated for the real numbers.
We know that the distributive property of multiplication states that we can multiply a sum of numbers by multiplying each addend separately and finally add the products.
a*(b+c)= a*b+a*c
where a,b and c are real numbers.
3(x+1)= 3*x+3*1 = 3x+3
Therefore the correct option is distributive postulate....
Answer:The amount of paint that was sold altogether is 173.36 litres
Step-by-step explanation:
The total amount of paint that the paint shop stocks is 1800 litres.
24% of the paint is white. It means that the amount of white paint would be
24/100 × 1800 = 0.24 × 1800 = 432 litres.
The amount of the remaining paint other than white would be
1800 - 432 = 1368 litres
The shops sells 18% of the white paint. This means that the amount of white paint sold by the shop will be
18/100 × 432 = 0.18 × 432 = 77.6 litres.
The shops sells 7% of the rest of the paint.
This means that the amount of the rest paint sold by the shop will be
7/100 × 1368 = 0.07 × 1368 = 95.76 litres.
The amount of paint that was sold altogether would be
77.6 + 95.76 = 173.36 litres
Answer: $2
==================================
Since 3 pencils and 1 notebook that costs $6 cost $12 in total:
3p + 6 = 12
3p = 12 - 6
3p = 6
p = 6÷3
p = 2
Therefore, the cost of each pencil is $2
