Long division is easier than you think. Here's how to solve this problem:
1. See how many times 36 can go into 66.
Multiply until you reach a number that is closest (or exact) to 66.
36 x 1 = 36; 36 x 2 = 72.
72 is over 66, so 2 doesn't work. Therefore, we'd put "1" in the first space on the shelf (right above the 6).
2. Subtract.
Now that we have "1" on the shelf, you need to subtract 36 by 66. We do this because 36 x 1 is 36. If it were the number "2" on the shelf, we'd subtract 72, and so on.
66 - 36 = 30.
3. See how many times 36 can go into 30.
Since it can't go into 30, we bring the 3 down (hence the arrow pointing down). The number is now 303.
4. See how many times 36 can go into 303.
I won't write it all out, but after multiplying 1-7 by 36, we find that the closest solution is 36 x 8 = 288.
We put "8" on the shelf, next to "1".
5. Subtract.
Now that "8" is on the shelf, we subtract 288 by 303, which gives us 15.
Since 36 cannot go into 15, and there are no more numbers we can drag down, your remainder is 15.
Your answer is:
36 R 15
The first two boxes under 663 should be filled with 36, the next three under that should have 303, the next three should have 288, and the final two boxes should have 15.

Answers
Answer: Jarrah has to rake 25 bags.
Step-by-step explanation: Jarrah
Jarrah needs to get $159 dollars, right? Well since he already has $38, we just need to subtract 159 and 38. 159-38 is 121. (121 is how much heneeds )Each bag raked costs $5, and 5 can't go into 121, so it's best to have more than less. Multiply 5 and 25, and you will get $125. That is more than enough, you cannot do 5x24 because it would be 120, which is too low. Therefore, Jarrah needs to rake 25 bags.

The area of a rectangle a=1(w) is represented by the expression 24x6y15. If the width of the rectangle is 2x3y9, what is the length of the rectangle
Answers
Answer:
Length of rectangle is: [tex]Length=12x^3y^6[/tex]
Step-by-step explanation:
The area of rectangle = [tex]24x^6y^{15}[/tex]
Width of rectangle = [tex]2x^3y^9[/tex]
We need to find length of rectangle
The formula used is: [tex]Area=Length\times Width[/tex]
Putting values and finding length
[tex]Area=Length\times Width\\24x^6y^{15}=Length\times 2x^3y^9\\Length=\frac{24x^6y^{15}}{2x^3y^9} \\Length=12x^{6-3}y^{15-9}\\Length=12x^3y^6[/tex]
So, Length of rectangle is: [tex]Length=12x^3y^6[/tex]

Which inequality correctly compares Three-fourths, One-seventh, and Five-sixths? One-seventh < Three-fourths < Five-sixths One-seventh < Five-sixths < Three-fourths Three-fourths < Five-sixths < One-seventh Three-fourths < One-seventh < Five-sixths
Answers
Answer:
The inequality which correctly compares Three-fourths, One-seventh, and Five-sixths is : One-seventh < Three-fourths < Five-sixths.
The first option is correct.
Step-by-step explanation:
To determine which inequality correctly compares Three-fourths, One-seventh, and Five-sixths, we will arrange them in ascending order.
To do this, first, we will determine the LCM of the fractions denominators..
Three-fourths, One-seventh, and Five-sixths
[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex]
The denominators are 4, 7 and 6.
LCM of 4,7 and 6 is 84
Then, we will write the fractions in a form whereby they all have the same denominators.
[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex] can be written as
[tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex]
The resulting order of the numerators gives the order of the fractions.
Now, we will arrange [tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex] in ascending order. This becomes
[tex]\frac{12}{84}, \frac{63}{84},and \frac{70}{84}[/tex].
∴ The ascending order of the fractions is [tex]\frac{1}{7}, \frac{3}{4},and \frac{5}{6}[/tex].
That is, One-seventh, Three-fourths, and Five-sixths.
Hence, we can write that
One-seventh < Three-fourths < Five-sixths.
This is the inequality which correctly compares Three-fourths, One-seventh, and Five-sixths

Answers
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x - 17 + 3x + 8 + x + 13 = 180
8x + 4 = 180
8x = 176
x = 22
<A = 4x - 17
<A = 4*22 - 17
<A = 88 - 17
<A = 71
============
<B = 3x + 8
<B = 3*22 + 8
<B = 66 + 8
<B = 74
============
<C = x + 13
<C = 22 + 13
<C = 35
A B and C add to 180 as they should.
