a) As Mauricio stacked triple, it means he stacked three times as many cubes as Fernando.
Counting in the image, we see 7 stacked cubes. In this way, we have:
3 x 7 = 21
Maurício stacked 21 cubes.
b) If he had stacked the quadruple, it would have been four times as much.
4 x 7 = 28
Mauritius would have stacked 28 cubes.
a) Double is multiplying by two.
2 x 2 = 4
Fabricio scored 4 points.
b) The triple is to multiply by three.
2 x 3 = 6
Jussara scored 6 points.
c) The fourfold is to multiply by four.
2 x 4 = 8
Fernanda scored eight points.
d) The quintuple is to multiply by five.
2 x 5 = 10
Patrick scored ten points.
a) To each term, we add 3 units. Since the first term is three, all others are the results of multiplying by 3.
The fourth term will be: 4 x 3 = 12. The sequence up to the tenth term is:
3, 6, 9, 12, 15, 18, 21, 24, 27, 30
b) To each term, we add 5 units. Since the first term is five, all others are the results of multiplying by 5.
The fourth term will be: 4 x 5 = 20. The sequence up to the tenth term is:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
c) To each term, we add 7 units. Since the first term is seven, all the others are the results of multiplying by 7.
The fourth term will be: 4 x 7 = 28. The sequence up to the tenth term is:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70
a) As there are eight teams formed by six players each, they will be:
6 x 8 = 48
There are forty-eight vacancies for holders.
b) For each team, 6 starters and 6 reserves are called up, that is, 12 players per team.
How are eight teams:
12 x 8 = 96
Ninety-six players will be called up.
a) There are 8 cartons of eggs.
b) There are six eggs per box.
c) 8 x 6 = 48. There are 48 eggs in total.
d) A dozen equals 12, so it takes two boxes to make a dozen.
2 boxes x 6 six eggs = 12 (one dozen)
Since there are 48 eggs, we have:
12 + 12 + 12 + 12 or 12 x 4 = 48
So there are 4 dozen eggs. As each dozen costs R$16.00, selling all four, he will raise:
16 x 4 = 64
It will raise R$64.00.
Answer: 1 620 pages.
As there are 36 comics in his collection, and each has 45 pages, he read:
36 x 45 = 1 620
Henrique read 1,620 pages in his collection.
Lentil: 3 packs
Price per package: R$11.00
3 x BRL 11.00 = BRL 33.00
Pea: 4 packs
Price per package: R$8.00
4 x R$8.00 = R$32.00
Avocados: 2 pieces
Price per unit: R$4.00
2 x BRL 4.00 = BRL 8.00
Wholemeal bread: 10 pieces
Price per unit: BRL 1.00
10 x BRL 1.00 = BRL 10.00
Soy Protein: 3 packets
Price per unit: R$6.00
3 x BRL 6.00 = BRL 18.00
Adding the amounts
33 + 32 + 8 + 10 + 18 = 101
Thus, Akeny spent one hundred and one reais in the market.
