Answer:
12/30
Step-by-step explanation:
So we know that the denominator-numerator=18
And we also know that it's equal to 4/10 or 2/5.
Soooooooooooooo the most easiest is just to trial and error: 12/30
But I don't really know the more complex formula...

how do i solve for n in this problem -6n - (3n - 9) + 5n = -4 (2n - 8)
Answer:
-6n -(3n - 9) + 5n = -4 (2n - 8)
-6n -3n +9 +5n = -8n +32
-9n +5n +9 = -8n +32
-4n + 9 = -8n +32
8n - 4n = 32 - 9
4n = 23
n = 23/4 = 5.75

How many distinct positive integer-valued solutions exist to the equation (x2 - 7x + 11)(x2 - 13x + 42) = 1
Answer:
The given equation has TWO positive integer valued solutions, {6, 7}
Step-by-step explanation:
Here we are given two trinomial factors, each of which needs to be set equal to zero and in each case the resulting quadratic equation solved.
(x^2 - 7x + 11) has the coefficients {1, -7, 11}, and so the discriminant of this quadratic is b^2 - 4(a)(c), or 49 - 4(11), or 5.
Because this discriminant is positive, we know immediately that this quadratic has two real, unequal roots involving √5 (NO integer roots).
Next we focus on (x^2 - 13x + 42). The discriminant is b^2 - 4(a)(c), or
169 - 168, or 1. Again we see that there are two real, unequal roots:
+13 ± √1 +13 ± 1
x = --------------- or x = -------------
2 2
OR x = 14/2 = 7 (integer) or x = 12/2 = 6 (integer).
The given equation has TWO positive integer valued solutions, {6, 7}
Behind Lin’s house there is a kiddie pool that holds 180 or 680 units of water, depending on which unit you are using to measure. Which measurement is in gallons, and which is in liters?
180? 680?
Answer:
180 gallons of water; 680 liters of water
Step-by-step explanation:
theres about 3.78 liters in a gallon, and when you multiply that by 180 you get 680.4! gallons are bigger then liters, so they'd be less of them.
Marco’s bank statement says that he has an ending balance of $81. What is Marco’s starting balance?
Answer:
$255
Step-by-step explanation:
Using the information provided, in order to find Marco's starting balance we simply need to add all of his transaction costs together. Once we have this value we simply add it to his ending balance amount which will give us the total dollar value of his starting balance.
20 + 22 + 13 + 39 + 34 + 15 + 31 = 174
174 + 81 = $255
Finally, we can see that Marco's starting balance was a total of $255
Answer:
A
Step-by-step explanation:
$255

Step-by-step explanation:
3 3/4 divided by 5/7 write the quotient in lowest terms.
Answer:
5 1/4
Step-by-step explanation:
Rewrite 3 3/4 as an improper fraction
3 3/4 = 15/4
Now you have
15/5 / 5/7
When you divide fractions, change the division to multiplication and flip the second fraction over:
15/4 x 7/5
Now multiply the top numbers together and the bottom numbers together:
( 15 x 7) / (4 x 5) = 105/20
Write as a proper fraction:
105/20 = 5 1/4

Write a word problem that could be solved using the division equation
16 divided by 2 =8
Answer:
Step-by-step explanation:
A word problem that represents division equation '16 divided by 2 =8' is Dayana and his friend John bought a 12lb bag of candy at the grocery store. If they want to share it equally, how much candy will each person get?
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
We have expression:
16 divided by 2 =8
In numerator form,
16 ÷ 2 = 8
Dayana and his friend John bought a 12lb bag of candy at the grocery store.
If they want to share it equally, how much candy will each person get?
16 ÷ 2
16 / 2 = 8
16 divided by 2 =8
The quotient is 8.
It means that each person will get 8lb of candy.
Therefore, the problem is, Dayana and his friend John bought a 12lb bag of candy at the grocery store. If they want to share it equally, how much candy will each person get?

Step-by-step explanation:
The area of cylinder is the area of the base (pi r^2) and the height (5)
Answer:
C
Step-by-step explanation:
Well if you think about it the normal formula is V=πr^2h
A cylinders base is a circle and the area for a circle is πr^2
If you cancel πr^2 you are left with height
So therefore it would be V=area of the base*height

Look at the two rectangles on the centimetre square grid.
B
A
a)
Which rectangle (A or B) has the larger area? a
b) Explain how you know.
Answer:
A has the larger area.
Step-by-step explanation:
You can find a rectangle's are by multiplying its width by its height.
For triangle A the width is 5, and the height is 3. 5 × 3 = 15
For triangle B the width is 6 and the height is 2. 6 × 2 = 12
15 is greater than 12, so rectangle A has a larger area than rectangle B.
The area of rectangle [1] is greater than rectangle [2].
What is a rectangle?A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
Given are two rectangles.
Assume that the side of the square block is 1 unit.
Now, for rectangle [1], we can write -
A [1] = L x B = 5 x 3 = 15 units square
For rectangle [2], we can write -
A [2] = L x B = 6 x 2 = 12 units square
Now, A[1] > A[2]
Therefore, the area of rectangle [1] is greater than rectangle [2].
