Use the Distributive Property to evaluate: 3(21 + 6)
Answer:
81
Step-by-step explanation:
3(21 + 6)
(3 x 21) + (3 x 6)
63 + 18
81
Answer:
3*21+3*6 = 81
Step-by-step explanation:
3(21+6) is basically 3 times 21 plus 3 times 6. You are distributing the 3 to the 21, and then also to the 6. Once you distribute the 3, you get 3*21+3*6. First, multiply 3 by 21 to get 63. Then, multiply 3 by 6 to get 18. Follow the equation and add them together to get your answer of 81.
You could also do it a different way and instead of doing 3*21+3*6, you could do the original equation, and do 3(21+6). 21+6=27 You then have 3(27). 3 times 27 is 81. You get the same answer, you could just do it a different way.

Sal made 8 ft of sausage links on Friday morning. He used 4 ft for dinner service on Friday night. On Saturday morning, he made another 8 ft of sausage links and used 12 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night?
Answer:
Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft
Step-by-step explanation:
Amount of sausage links made on Friday morning = 8 ft
Amount of sausage links used on Friday night = 4 ft
Amount of sausage links remaining = 8 - 4 = 4ft (i)
Amount of sausage links made on Saturday morning = 8 ft (ii)
So,
Total amount of sausage links = 8 + 4 = 12 ft (from (i) and (ii) )
Amount of sausage links used on Saturday night = 12 ft
Amount of sausage links remaining = 12 - 12 = 0 ft
Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft
Sharon wants to make cookies for her class bake sale. She found a recipe that calls for 2/3 cups of flour for each batch of cookies. How many batches can she make using 12 cups of flour?
Answer:
18
Step-by-step explanation:
Multiply 12 and 2 by 3 to get the "easier to work with" fraction
[tex]\frac{12}{1}[/tex] = [tex]\frac{36}{3}[/tex]
Now, multiply two until you get 36
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36
It takes 18 times to get to 36.
That means the answer is 18.

Which table represents a linear function?
pls answer quick :)
Answer:
The first table
Step-by-step explanation:
A linear function is represented when x and y are increased at a constant rate. In the first table, you can see that as x increases by 1, y increases by 1/2, thus the first table is a linar function.

For the following equation, find a solution for the variable. Show all of your work and use complete sentences to explain the solving process that you used to find a solution for the equation. Be sure to include at least two terms from the word bank.
6 = 3 x - 9
Answer:
x=5
Step-by-step explanation:
solution;
6=3x-9(carry alike terms to the same side that'd be +6-9)
+9+6=3x
15=3x(divide both sides by 3)
5=x
(thanks,sorry and welcome)
The solution to the given equation 6 = 3x - 9 would be variable x = 5.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
To determine a solution for the variable in equation 6 = 3x - 9, we can begin by isolating the variable on one side of the equation. To do this, we can add 9 to both sides, giving us:
6 + 9 = 3x
This simplifies to:
15 = 3x
The next step is to divide both sides of the equation by 3, which will give us the value of x.
15/3 = 3x/3
Simplifying we get
5 = x
Thus, the solution for the variable is x = 5.

Sam ordered some books online for $5 each. He paid a total of $4 for shipping. The total cost of the purchase was $89. How many books did he buy?
Part a is the equation and part b is the total
Answer:
17
Step-by-step explanation:
if you subtract 4 from 89, which is the shipping cost. 89 - 4 = 85. Then divided 85 by 5 because that will show how much he paid for them in total, by how much a singular book is. Telling you how many books he bought. 85/5 = 17.
Answer:
A.) 5b+4=89
B.) 17 books
Step-by-step explanation:
To find A.), we must create a linear equation. Let b be the number of books Sam ordered. We write 5b because each book is 5 dollars. Then we add 4 dollars to the equation to represent the shipping fee. Then we write "equals to 89", because it says that is the total cost. So we get the equation 5b+$4=$89
To find B.), we must solve the equation. Isolate the variable, by subtracting 4 from both sides. We then get 5b=$85. Now we divide by 5 to get only the variable and to get rid of the coefficient. We get b=17. So Sam bought 17 books.

Tickets to a 3D movie cost $12.50 for adults and $8.50 for children. The theater can seat up to 180 people. A total of $1826 was collected in ticket sales for the sold out 7:15 PM show. Determine the number of adult tickets and the number of children’s tickets that were sold.
Answer:
74 adult tickets and 106 children tickets
Step-by-step explanation:
let x be the number of adults tickets sold out
and y the number of chlidrens tickets that sold out for the 7:15 pm show
The equations that determine our problem are
x+y=180
12.50x+8.50y=1826
lets separate x from first equation x=180-y and replace at the second equation
12.50(180-y)+8.50y=1826
12.50*180-12.50y+8.50y=1826
2250-4y=1826
4y=2250-1826
y=424/4=106
so x=180-y=180-106=74
2. The hamster, x, walked 20 feet. The guinea pig walked 1/4 less than that. The guinea
pig walked
feet
You question is a little unclear but I'm going to assume you meant how much the guinea pig walked.
The hamster walked 20 feet, and the guinea pig walked 1/4 less. So you find 1/4 of 20, which is 5. Then, you subtract 20 and 5: 20-5 = 15. So the guinea pig walked 15 feet.

form to write an equation of the line.
To find the point slope of a line you must first know the slope of the two points. You would substitute the points into the slope formula y2-y1/x2-x1.
Then you would put the slope into the point slope formula:
y-y1=m(x-x1)
"m" is the slope of the formula.

If u place a 13 foot ladder against a 12 foot building,how many feet will the Ladder be from the building
Answer:
5 feet
Step-by-step explanation:
When you place the 13 foot ladder, the ladder, floor, and wall forms a right triangle and the ladder will become the hypotenuse.
We use the Pythagorean Theorem. Let x be the distance from the building.
x^2 +12^2 = 13^2
x^2 + 144 = 169
x^2 = 169 - 144
x^2 = 25
Take the square root of 25 and you get 5
x = 5
If 3x+4=-5, what does x equal to?
First subtract 4 from both sides to isolate the 3x.
That leaves us with 3x = -9.
Since x is being multiplied by 3, to get x by itself,
we need to divide both sides of the equation by 3.
So our final answer is x = -3.
Answer:
x = -3
Step-by-step explanation:
3x + 4= -5
Subtract 4 from both sides.
3x = -9
Divide both sides by 3.
x = -3

Answer:
C. l
Step-by-step explanation:
The square root of 52 is about 7.211.
Since there is a negative sign in front of the square root, then it means that the answer is about -7.211.
On the number line you have a little bit over -7.3, a little less than -7.3 and a little more than -7.2. The closest answer would be the point that is a little more than -7.2.
