Answer:
21
Step-by-step explanation:
Equivalent Fractions with the LCD
8/21 = 8/21
2/7 = 6/21
Solution:
Rewriting input as fractions if necessary:
8/21, 2/7
For the denominators (21, 7) the least common multiple (LCM) is 21.
LCM(21, 7)
Therefore, the least common denominator (LCD) is 21.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
8/21 = 8/21 × 1/1 = 8/21
2/7 = 2/7 × 3/3 = 6/21

Answer:
y=8/7
Step-by-step explanation:
Or 1 1/7
Or 1.14
Hope this helps!
Answer:
[tex]y=\frac{8}{7}[/tex]
OR
[tex]y=1\frac{1}{7}[/tex]
Step-by-step explanation:
Luckily for you, I'm pretty decent in math
Here's how I did it: [tex]\frac{14y}{14} = \frac{16}{14}[/tex] (Divide 14 on both sides)
Give you y = 8/7
The length of a side of an equilateral triangle is x−4.5.
First, express its perimeter as a sum.
Next, express its perimeter as a product.
Answer:
The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5).
Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)
1. Perimeter(as sum) = a+b+c
= (x-4.5)+(x-4.5)+(x-4.5)
= x+x+x-4.5-4.5-4.5
= 3x - 13.5
2. Perimeter (as product) = 3×a
= 3×(x-4.5)
= 3×x - 3×4.5
= 3x - 13.5
(you can write 3×b or 3×c also as a=b=c.)
Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.

Jim's lawn is a rectangle that is 15 5/6 yards long and 10 2/5 yards wide. Jim buys sod in pieces that are 1 1/3 yards long and 1 1/3 yards wide. How many pieces of sod will Jim need to buy and cover his lawn?
Answer:
Its 93
length of Jim's backyard , L = 15 5/6 = 95/6 yards
width of Jim's backyard , B = 10 2/5 = 52/5 yards
so, area of rectangular backyard = L × B
= 95/6 × 52/5
= (95 × 52)/30
= 494/3 yard²
Jim buys sod of length 1 1/3 = 4/3 yards and width = 1 1/3 yards = 4/3 yards .
so, area of rectangular sod = length × width
= 4/3 × 4/3 = 16/9 yard²
number of sod = area of backyard or area of sod
= (494/3)/(16/9)
= 494 × 3/16
= 92.625 ≈ 93
therefor, 93 pieces of sod will Jim need to buy to cover his backyard.

rewrite 1/4 book 1/3 hour as a unit rate
a. 12 books/hour
b. 1 1/3 books/hour
c. 1/12 books/hour
d. 3/4 book/hour
Answer:
The Answer would be D. 3/4 Book/Hour
Step-by-step explanation:
You would flip 1/3 to 3/1 which makes it a whole number. Then multiply 1/4 and 3.
1/4 x 3 which gives you 3/4.
Hence, your answer is 3/4
a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.
Answer:
2x - 30
Step-by-step explanation:
You have to subtract 3x + 18 from 5x - 12:
=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30
The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined
Answer = 2x - 30
Brittany and Will each made a triangular sign with an area of 8 square feet. The base of Brittany's triangle is half as long as the base of Will's. How do the heights of the triangles compare?
Answer:
the length of Brittany's triangular sign is 1/2 the length of Will's
Step-by-step explanation:
The height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).
How do the heights of the triangles compare?Let's assume the height of Brittany's triangle is h₁ and the height of Will's triangle is h₂.
For Brittany's triangle:
A = ¹/₂b₁h₁ = 8
For Will's triangle:
A = /₂b₂h₂ = 8
We are also given that the base of Brittany's triangle is half as long as the base of Will's triangle
b₁ = ¹/₂b₂
Now, let's find the relationship between the heights of the triangles:
From the equations above, we can see that:
h₁ = 16 / b₁
h₂ = 16 / b₂
Recall; b₁ = ¹/₂b₂
h₁ = (2 x 16) / b₂
h₂ = 16 / b₂
So, the height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

Which product is negative? −6⋅(−7)⋅(−8)⋅0 −3⋅(−2)⋅(−4)⋅(−7) −2⋅(−7)⋅12⋅(4) 4⋅(−9)⋅(−3)⋅(−1)
Answer:
Last choice
Step-by-step explanation:
To say it simply if products are in negative or not, we can tell by:-
Looking at negative symbolsThen count how many negative signs are there.If there are even-number signs (2 negative signs, 4 negative signs, etc.) then the product is positive.If there are odd-number negative signs (a negative sign, 3 negative signs, 5 negative signs, etc.) then the product is negative.The only choice that has odd-number negative signs is last choice — othere have 2 or 4 negative signs.
Additionally, keep in mind that:-
positive • positive = positivepositive • negative = negativenegative • negative = positivesame signs multiply each others = same signopposite signs multiply each others = negative (For plus and minus)Above are important fundamental to Algebra and many mathematic courses so you better remember it!

Answer:
-9
Step-by-step explanation:
27 divided by 9 equals 3 and the ^2 is 3x3 Which equals 9 and then the negative comes
Answer:
-9
Step-by-step explanation:
In this, you should use PEMDAS, parentheses, exponents, multiplication, division, addition, subtraction. It is the order of solving any equation. The first thing you should start with is the parentheses. -27/9 is -3. Since exponents come next, you would do -3 x -3, which equals 9. After that, all that is left is a negative sign being multiplied to 9 (which is in the parentheses still. The negative sign times 9 equals -9. Therefore, your answer is -9. You could check through just in case, but I hope its correct. Also, if you don't mind, could you mark brainliest? I would really appreciate it :D
Which number sentence represents the Associative Property of Addition?
22 + 3 = 25
22 + 3 = 25
0 + 90 = 90
0 + 90 = 90
18 + 7 = 7 + 18
18 + 7 = 7 + 18
4 + (1 + 11) = (4 + 1) + 11
According to the Associative property of Addition, when 3 or more numbers are added, the result (sum) remains the same even if the numbers are grouped in a different way. Here, grouping is done with the help of brackets.
This can be expressed as, a + (b + c) = (a + b) + c.
So, according to this the answer is 4 + (1 + 11) = (4 + 1) + 11.
