Find the quotient of 5/31 divided by 15/23

navik [9.2K]

The answer is 23/93. We Multiply and use the second fraction's reciprocal which becomes 5/31 multiplied by 23/15. 15 and 5 are common factors and we simplify them which turns 5 into 1 and 15 to 3. 23 multiplied by 1 is 23 and 31 multiplied by 3 turns to 93. This equals our final answer 23/93

How many cubic feet are in 3 cubic yards?

dimaraw [331]

For every cubic yard, it equals to 27 cubic feet.

So, could have this fraction $\frac{27 feet^3}{1 yards^3}$
And we want to convert 3 cubic yards into cubic feet.

We can express 3 cubic yards as $\frac{3 yards^3}{1}$

Now multiply the $\frac{3 yards^3}{1}$ fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.

$\frac{3 yards^3}{1} * \frac{27 feet^3}{1 yards^2} = \frac{81 feet^3}{1}$

So, 3 cubic yards to equal to 81 cubic feet.

I need help so someone plz give me the steps and answer and graph it so i can understand how to solve these types of problems ag

Eddi Din [679]

Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5

y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)

y = 4/5x - 3.6 ( y = mx + b formula)

4/5 = 0.8

y = 0.8x - 3.6

x = 1
y = 0.8(1) - 3.6
y = - 2.8

x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2

x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2

x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4

x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4

etc.

graph using the (x,y)

connect the dots

hope this helps

X^{2} - 8x + 7 = 0<br> Solve by completing the square. Also can you include steps?

iren [92.7K]

Answer:

{1, 7}

Step-by-step explanation:

Start with x^2 - 8x + 7 = 0.

We want to modify the first two terms to resemble x^2 - ax + b - b, where a is the coefficient (here -8) of the x term and b is the square of half of a.

Here, a = -8. Half of that is -4. The square of -4 is 16, and this is the value of b.

Write out x^2 - 8x as x^2 - 8x + 16 - 16. This is the perfect square of -4, added to x^2 - 8x and then subtracted from the result

Then the original equation, x^2 - 8x + 7 = 0, can be rewritten as:

x^2 - 8x + 16 - 16 + 7 = 0, and then as (x - 4)^2 - 9, or (x - 4)^2 = 9.

We want to solve this result for x. To do this, take the square root of both sides:

x - 4 = ±√9, or x - 4 = ±3.

Adding 4 to both sides, we get:

x = 4 ± 3. Thus, the solutions are x = 4 + 3 = 7 and x = 4 - 3 = 1.
