What is the least common denominator of 1/4, 3/7, 1/11

1 answer:

6 0

Alright. One way you can do this is to list multiples of each denominator:

1/4:
4, 8, 12, 16, 20, 24, 28, 32, 36...... and so on

3/7:
7, 14, 21, 28, 35, 42, 49, 57, 63......

1/11;
11, 22, 33, 44, 55, 66, 77, 88......

Keep going until you see the least common denominator!

Now an easier way to do this is by multiplying all of the numbers in the denominator then get the factors:

4*7*11 = 308

And since those are not divisible by a whole number (besides 4 but 308 won't be divisible by 2*7*11)

Therefore 308 is the least common denominator.

Setler79 [48]

Answer:

y = -2x - 1

Step-by-step explanation:

y = -2x + b

3 = -2(-2) + b

3 = 4 + b

-1 = b

y = -2x - 1

Pls pls pls pls pls help

Answer:

$y=\frac{1}{2}$

Step-by-step explanation:

$4(y+1)= \frac{3}{1-y}$

$4y+4= \frac{3}{1-y}$

$(4y+4)(1-y)= 3$

$4y(1-y)+4(1-y)=3$

$4y-4y^{2} +4-4y=3$

$-4y^{2}=3-4$

$4y^{2}=1$

$y^{2} = \frac{1}{4}$

$y=\sqrt{\frac{1}{4} }$

$y=\frac{1}{2}$

The length of a rectangle is 24 units. Can the perimeter P of the rectangle be 60 units when its width w is 11 units?

marishachu [46]

No it cannot because the perimeter is the sum of all the sides and a rectangle has 4 sides so 24x2 + 11x2 = 70. So the perimeter would be 70 not 60.

Hope this helps :)

Answer:

18 dimes, 12 quarters

Step-by-step explanation:

We are to solve the system of linear equations for D and Q, where D is the number of dimes and Q is the number of quarters.

Each dime is worth $0.10 and each quarter $0.25. Thus, D dimes are worth ($0.25/dime)D and Q quarters ($0.25/quarter)Q.

The sum of D and Q comes out to 30 coins, a mixture of dimes and quarters: D + Q = 30, so Q = 30 - D.

Now let's solve this equation: ($0.10/dime)D + ($0.25/quarter)Q = $4.80.

Substitute 30 - D for Q:

($0.10/dime)D + ($0.25/quarter)(30 - D) = $4.80

This is now entirely in D (no Q shows up). Performing the indicated multiplication, we get 0.10D + 0.25(30) - 0.25D = 4.80

Combining like terms: 0.10D - 0.25D = -0.15D, and -7.5 + 4.80 = -2.7

Thus, -0.15D = -2.70, and so D = 2.70/0.15 = 18 (There are 18 dimes.)

Since Q = 30 - D, and D - 18, Q = 30 - 18 = 12 (There are 12 quarters)
