<span>2a(-4b) + 3a(2a+6b)
= -8ab + 6a^2 + 18ab
= 10ab + 6a^2

6(6a - b) + 2a(b-3) / 2
= 36a - 6b + a(b-3)
= 36a - 6b + ab - 3a
= 33a - 6b +ab

Divide 56 in a ratio of 5.3
Varvara68 [4.7K]
In order to find what one part is in a ratio, you have to add the ratio up ( 5+ 3) and divide it by the number you're looking for (56). In this case, you get 56/8, which gives you 7. Therefore, each part is worth 7. You then have to multiply both sides of the ratio (5 and 3) by 7. 5x7= 35. 3x7= 21. Therefore, 56 divided into the ratio of 5:3 is 35:21

A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n
algol [13]
Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25
