There are 24 female performers in a dance recital. The ratio of men to women is 3:8. How many men are in the dance recital? There are men in the dance recital.

Answers

Answer:

Step-by-step explanation:

There are 24 women

24/8 = 3

Multiply each term by 3

3*3      8*3         11*3

9           24         33

There are 9 men at the recital

8x = 24(3)
8x = 72
x = 9
there are 9 men

Please help it’s multiple choice! No links

Answers

Answer:

Option A, B, and D are true.

Explanation:

A coefficient is the number that is being multiplied by a variable. For example, in 7b, 7 would be the coefficient.

Terms are the numbers used in the equation. For example, in 3 + 2, 3 and 2 would be the terms.

3n and 5m are not coefficients as there are variables included. 3n and 5m are examples of a variable.

A constant is a number that is not multiplied by a variable. For example, in 8x + 3 + 2b, 3 would be the constant.

Answers

Answer:

No Solution

Step-by-step explanation:

We are given the equation:

[tex]\displaystyle \large{|x|-5=-20}[/tex]

First, Add both sides by 5 which leaves us [tex]\displaystyle \large{|x|=-15}[/tex]

By definition, an absolute value cannot be negative. There are no x-values that can equal to -15 because no matter what real numbers you put in or substitute, it will never become negative.

Hence, no solution.

Answers

5y-8(5y+2)=-(25y+46)
Multiply so there are no parentheses
5y-40y+16=-25y-46
Add 40y to both sides
5y+16=15y-46
Add 46 to both sides
5y+62=15y
Subtract 5y from both sides
62=10y
Divide both sides by 10
