Help Please I Dont Know What To Do

Answers

Answer 1

okay so for the first one it's 3b-16

but when you see b=8 you would rewrite it as 3×8- 16 and once you do that you should have the answers you do the same thing for the rest of them :)

Answer 2
All you do is replace the a’s and b’s in the expressions with the values they give you.

For example, for 3b - 16, you put 3(8) - 16 because they state that b = 8.

Find two consecutive odd integers such that
4 times the smaller integer is 19 less than 5
times the larger integer.

Answers

Answer:

9 and 11

Step-by-step explanation:

let the consecutive odd integers be n and n + 2 , then

4n = 5(n + 2) - 19 , that is

4n = 5n + 10 - 19 ( subtract 5n from both sides )

- n = - 9 ( multiply both sides by - 1 )

n = 9 and n + 2 = 9 + 2 = 11

The 2 integers are 9 and 11

Find the value of x.

Answers

Answer:

x = 13

Step-by-step explanation:

Sum or interior angles of a triangle is 180,

6x + 19 + 5x - 15 + 3x - 6 = 180

6x + 5x + 3x + 19 - 15 - 6 = 180

14x + 19 - 21 = 180

14x - 2 = 180

14x = 180 + 2

14x = 182

x = 182 / 14

x = 13

What is the result when the number 40 is decreased by 50%

Answers

Answer:

20

Step-by-step explanation:

40 x 50% = 20

So 50% of 40 equals to 20. Now, since it says decreased by 50%, we have to subtract 20 from 40 because we already know that 20 is the 50%. So 40 - 20 gives you 20.

Rosemarie has 16 grandchildren and they will each get 0.50 cents

Answer:

a. Rosemarie has 16 grandchildren.

b. Each grandchild would receive $0.50 or 50 cents.

Step-by-step explanation:

a. There are 4 sons, and each son has 4 children.

Son 1: 4 children

Son 2: 4 children

Son 3: 4 children

Son 4: 4 children

So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16

Rosemarie has 16 grandchildren.

b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).

And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50

Each grandchild would receive $0.50 or 50 cents.
