Mr. Diaz bought a board that was 7 feet long. He cut the entire board into pieces that were LaTeX: \frac{1}{3}1 3 foot long. How many pieces did Mr. Diaz have ?
Answer: Mr. Diaz will have 21 pieces.
Step-by-step explanation:
Given, Length of the complete piece bought by Mr. Diaz= 7 feet
Length of each piece cut = [tex]\dfrac13[/tex] foot
By division operation,
Number of pieces = ( Length of complete piece ) ÷ (Length of each piece cut)
[tex]=7\div\dfrac13=7\times3=21\ \ [\because a\div \dfrac{b}{c}=a\times\dfrac{c}{b}][/tex]
Hence, Mr. Diaz will have 21 pieces.

Solve each equation. Check your solution.
Answer:
y = 15
Step-by-step explanation:
-1/3 y -6 = -11
Add 6 to each side
-1/3 y -6+6 = -11+6
-1/3 y = -5
Multiply each side by -3
-1/3 y * -3 = -5*-3
y = 15
Check
-1/3 *15 -6 = -11
-5 -6 = -11
-11=-11
Is it possible for two numbers to have a difference of 5, and a sum of 12?
Answer:
yes, 8.5 and 3.5
Step-by-step explanation:
8.5 + 3.5 = 12
8.5 - 3.5 = 5
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The two numbers are 8.5 and 3.5.
Yes, it is possible to have two numbers that have a difference of 5 and a sum of 12.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
3x = 4 + 3 is an equation.
We have,
Let the two numbers be M and N.
Now,
Two numbers have a difference of 5.
This can be written as,
M - N = 5 _____(1)
Two numbers sum is 12.
This can be written as,
M + N = 12 _____(2)
From (1) and (2) we get,
M - N = 5
M = 5 + N _____(3)
Putting (3) in (2)
M + N = 12
5 + N + N = 12
5 + 2N = 12
2N = 12 - 5
2N = 7
N = 7/2
N = 3.5
Putting in (3) we get,
M = 5 + 3.5
M = 8.5
We can cross-check.
M - N = 5
8.5 - 3.5 = 5 (PROVED)
M + N = 12
8.5 + 3.5 = 12 (PROVED)
Thus,
The two numbers are 8.5 and 3.5.
Yes, it is possible to have two numbers that have a difference of 5 and a sum of 12.

8. (-5, 14) and (-3,11)
9. (-18, 16) and (2, -9)
10. ( 4, 6) and (1,2)
Answer:
1. Slope = -4/5
2. Slope = 2/3
3. Slope = 0
4. Slope = 3/-4
5. Slope = 7/-12
6. Slope = 1/2
7. Slope = -2/0 --> Undefined
8. Slope = 3/-2
9. Slope = 5/-4
10. Slope = 4/3
Step-by-step explanation:
Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:
10-2/1-11 = 8/-10 = -4/5

A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.

A relation is a collection of Ordered pairs where each x-value is paired with only one y-value.
What do you mean by domain and range of a function?
For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of x for which [y] exists.
Given is the graph of a equation
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x, y) is in the relation.

Answer:
-Freddy tiene 25 billetes de diez dólares.
-A Freddy le quedan 19 billetes de diez dólares.
Step-by-step explanation:
Para encontrar la cantidad de billetes de diez dólares que tiene Freddy, tienes que dividir la cantidad total que tiene entre diez:
250/10=25
Esto significa que Freddy tiene 25 billetes de diez dólares.
Para saber cuantos billetes le quedan a Freddy, tienes que restar los 6 billetes que le dio a su hermano del total de billetes que tenía:
25-6=19
De acuerdo a esto, a Freddy le quedan 19 billetes de diez dólares.

Answer:
x = 44.5
Step-by-step explanation:
The angles defined by x will be supplementary when the lines m and n are parallel.
(x +4) +(3x -2) = 180
4x +2 = 180
4x = 178
x = 44.5 . . . . will make m and n parallel
Determine the measures of angles C and D.
Answer:
c = 40 and d = 76
Step-by-step explanation:
this is going to take me a long time to explain but here we go
so you need to do 180 - 116 and get 64.
then create a equation that is like this 7y + 6 + 4y + 64 = 180
when you solve it you get y = 10
then plug in 10 in for y in 4y. and you get 40 for c
do the same for d and you will get 76

David's bowling score is 6 less than 3 times Aaron's score. The sum of their scores is 214. Find the score of each student. Use the variable a for Aaron's score.
plz help
Step-by-step explanation:
Let aron's variable be = a
Let davids variable be( 6 less tan 3 times aron) = 3×a-6
Thier sum is =214
So,
3×a-6 + a = 214
3a -6 +a = 214
(transpose)
3a + a = 214 + 6
4a = 220
a = 220/4
a= 55
Thus,aron's score is = 55
And davids score is (3×a-6) = 3×55-6 = 159
Checking,
Aron score + david score = 214
55 + 159 = 214
SO, ITS CORRECT

A librarian sorts 450 books at a constant rate. After 4 days, the librarian still has 150 books to sort. How much time does it take to sort the books from start to finish?
Answer:
6 days
Step-by-step explanation:
hope this helps
A librarian sorts 450 books at a constant rate. After 4 days, the librarian still has 150 books to sort. Then 6 days time does it take to sort the books from start to finish
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The librarian sorted at a constant rate, then they sorted the same amount of books all 4 days.
450-150=300
If they still have 150 books left to sort, then they sorted 300 books over 4 days.
300/4=75
This means that they sorted 75 books per day.
150 divided by 75 is 2
So it will take 2 more days to finish sorting all the books.
So altogether, it will take 6 days to sort all of the books.
Hence 6 days time does it take to sort the books from start to finish

x = 4[tex]\frac{1}{2}[/tex] teaspoons of baking powder
Step-by-step explanation:
I will use ratio, so for every 10 muffins we need 1[tex]\frac{1}{4}[/tex] or [tex]\frac{5}{4}[/tex] teaspoons of baking powder. How much would we need for 3 dozens or 36 muffins?
Set up the ratio in fractions
[tex]\frac{10}{\frac{5}{4}}[/tex] = [tex]\frac{36}{x}[/tex]; where x is the teaspoons of baking powder
solve for x
x =(36*[tex]\frac{5}{4}[/tex]) / 10
x = (45)/10 = 4[tex]\frac{5}{10}[/tex] = 4[tex]\frac{1}{2}[/tex] teaspoons of baking powder

Grayson biked 45 miles in 3 hours.Maya bikes 26 miles in 2 hours.If they both kept a constant speed,how much faster did Grason Bike than Maya
Write your answer as a decimal or a whole number
Answer:
2
Step-by-step explanation:
Divide 45 and 3, then divide 26 and 2. subtract those answers and u get 2. (the dude that said your mom has no life and got his mom raped)
Grason's Bike is 2 miles/hour faster than Maya's if Grayson biked 45 miles in 3 hours. Maya bikes 26 miles in 2 hours.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
Grayson biked 45 miles in 3 hours. Maya bikes 26 miles in 2 hours.
As we know,
The speed = distance/time
Plug the respective values in the above formula:
For Grayson:
speed = 45/3 = 15 miles/hour
For Maya:
speed = 26/2 = 13 miles/hour
Difference in speed = 15 - 13 = 2 miles/hour
Thus, Grason's Bike is 2 miles/hour faster than Maya's if Grayson biked 45 miles in 3 hours. Maya bikes 26 miles in 2 hours.
