7b + 3 – 4b = 3 – 3(b + 4)

svlad2 [7]

Hello from MrBillDoesMath!

Answer: b

Discussion:

7b + 3 - 4b = 3 - 3(b+4) =>

7b + 3 - 4b = 3 - 3b -12 =>

(7b - 4b) + 3 = -3b - 9 =>

3b + 3 = -3b -9 => Add 9 to both sides

3b + 12 = -3b -9 + 9 =>

3b + 12 = -3b => ( add 3b to both sides)

6b + 12 = 0 => (subtract 12 from both sides)

6b = -12 =>

b = -12/6 = -2

Thank you,

The coach of a baseball team separates the players into groups for drills.Each group has the same number of players. Is the tota

scZoUnD [109]

Answer:it is composite

Step-by-step explanation:

it is composite because if there is say 60 people on the team and he divided the groups amongst three people in each group then it would be 20 groups now that isn't prime see so it would be the same thing if the basketball coach separates the team into 10 groups and there's 60 people on that team that's not a prime number that would be a composite number so the answer is composite A prime number would be there's eight people in each group and he separates them into a group so that means that They would be 64 people on that team Now the book that I'm looking at right now doesn't tell you the people on that team and how much people there are on that team but it says there is a different amount from The number of teams to the number of people in the team see there's like eight people in the team and there is for groups so that means two people in each group so That means that the answer would have to be composite and not prime hope this helped somebody.

Three brothers Charlie Robert and Nicholas have 21 video games Charlie has twice as many games as Robert. Robert has 5 fewer gam

AVprozaik [17]

Answer:

The equation would be $4x-15=21$ .

Step-by-step explanation:

Given;

Total Number of Video games = 21

Let the number of video game Nicholas has be 'x'.

Now Given:

Robert has 5 fewer games than Nicholas.

so we can say that;

number of video game Robert has = $x-5$

Also Given:

Charlie has twice as many games as Robert.

so we can say that;

number of video game Charlie has = $2(x-5)=2x-10$

we need to write the equation.

Solution:

Now we can say that;

Total Number of Video games is equal to sum of number of video game Nicholas has, number of video game Robert has and number of video game Charlie has.

framing the equation we get;

$x+x-5+2x-10=21\\\\4x-15=21$
