Answer:
MAYA (6 minutes)
Amy (7 minutes)
Step-by-step explanation:
MAYA
Takes Maya 30 minutes to solve 5 Puzzle:
Let's express it as,
30 mins = 5 Puzzle
1 min = x Puzzle
Cross multiply to solve for the number of questions Maya solves in a minute.
It becomes:
30*x = 5*1
30x = 5
x = 30/5
x = 6mins.
It means it takes Maya 6 mins to solve one question.
FOR AMY
Takes Amy 28 mins to solve 4 puzzles.
Let's represent it as:
28 mins = 4 Puzzles
x min = 1 puzzle
Let's solve for x
(28 mins) * (1 puzzle) = 4 * x
28 = 4x
x = 28/4
x = 7 mins
It means, it takes Amy 7 minutes to solve 1 puzzle
Answer:
21
Step-by-step explanation:
PEMDAS
To find the zeros set the equation equal to zero:
x^2 - 5x +4 = 0
Factor:
(x-4) (x-1) = 0
Now solve each set of parenthesis so that they equal zero:
(x-4) = 0, x =4
(x-1) = 0, x = 1
The zeros are 1,4
Answer:
<em>T</em> = 5<em>g</em> + 3
Step-by-step explanation:
The information provided is summarized as follows:
- At party each guest receives five party favors
- The variable "<em>g</em>" represent the number of guests.
- Only three favors are left at the end.
Let <em>T</em> represent the total number of favors bought.
The expression representing the total number of favors given to the guests is:
5<em>g</em>.
Then the expression representing the total number of favors bought is:
<em>T</em> = 5<em>g</em> + 3
