The number of the blue cubes is 35 and the number of the red cubes is 20.
<h3>What is the ratio?</h3>
The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.
Given that:-
- In a bag, there are red and blue cubes in the ratio of 4: 7
- I add 10 more red cubes to the bag. Now there are red and blue cubes in the ratio of 6: 7
The number of the blue cubes are calculated as:-
The two equations will be formed by the given data in the question.
7r = 4b
7r + 70 = 6b
Solving the above equation we will get the value of b.
4b + 70 = 6b
6b - 4b = 70
2b = 70
b = 35
7r = 4b
7r = 4 x 35
r = 20
Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.

Divide both sides of the given equation by -3. This will give you |x-3| = 2.
Then either x-3=2, resulting in x= 5, or
-(x-3) = 2, or x-3 = -2, resulting in x=1
The solutions are {1,5}.
Answer:
The probability of him pulling a red marble is 12 to 30. The probability of him pulling a blue or purple marble is also 12 to 30.
Step-by-step explanation:
7+5+12+6=30 (all colors)
12 to 30 red ones
7+5+12+6=30 (all colors) and
7+5=12 (blue + purple)
12 to 30 blue or purple
71.5%
To solve, the easiest method I've found is to set up 2 fractions and cross multiply. so, x/100 = 105.1/147
Answer:
a) 1000 grams
b) 1250 grams
Step-by-step explanation:
Find out how much grams of sausage and dry pasta she needs for each person.
4 people = 400 g
1 person = 400 ÷ 4 = 100 g (sausage)
4 people = 500 g
1 person = 500 ÷ 4 = 125 g (dry pasta)
Find out how much grams of sausage and dry pasta is needed for 10 people.
10 person = 100 x 10 = 1000g (sausage)
10 person = 125 x 10 = 1250g (dry pasta)
