I GOT YOU.
First things first,
When multiplying fractions, it's super super super simple. Just multiply the numerator and denominator across, then simplify if needed!
________________________________
To solve your problem,
1. multiply the numerator across.
3 x 4 x 7 = 84
2. multiply the denominator across.
5 x 2 x 3 = 30
3. now you have the fraction $\frac{84}{30}$ (84/30 if you're on mobile)
4. simplify
84/30 has a common factor of 6. So it simplifies to 14/5.

Your answer is 14/5

In the equation 0.75 - 5/8s = 44, how do your combine the like terms?

Mnenie [13.5K]

Answer:

and let's then do away with the denominators, by multiplying both sides by the LCD of all fractions, in this case, the LCD will be 8, and then we'll combine the like-terms, but anyway, let's proceed.

Answer:

Recursive formula for geometric sequence

$a_{n}=a_{n-1}\times r$

is $a_{n}=a_{n-1}\times 6$

and explicit formula for geometric sequence $a_{n}=a_{1}^{r-1}$ is

$a_{n}=(\frac{1}{2})^{6-1}$

Step-by-step explanation:

Given sequence is $\frac{1}{2},3,18,108,648,...$

To find the recursive and explicit formula for this sequence:

Let $a_{1}=\frac{1}{2},a_{2}=3,a_{3}=18,a_{4}=108,a_{5}=648,...$

To find the common ratio r:

$r=\frac{a_{2}}{a_{1}}$

$=\frac{3}{\frac{1}{2}}$

$=3\times 2$

$=6$

Therefore r=6

$r=\frac{a_{3}}{a_{2}}$

$=\frac{18}{3}$

$=6$

Therefore r=6

Therefore the common ration r=6

Therefore the given sequence is geometric sequence

Recursive formula for geometric sequence is $a_{n}=a_{n-1}\times r$

$a_{n}=a_{n-1}\times 6$

and explicit formula is $a_{n}=a_{1}^{r-1}$

$a_{n}=(\frac{1}{2})^{6-1}$

$=(\frac{1}{2})^{5}$

$=\frac{1}{32}$

Therefore $a_{n}=\frac{1}{32}$

Answer: False

Step-by-step explanation:

Although it does go through y= -4

Doing Rise/Run we go up 2 and and over to the right 3 and see it does not cross through the point.

How do i write and solve for this inequality

Answer:

-7/4 < x < 8

Step-by-step explanation:

The value of y can be determined from the sum of the angles, so you know each of the angles exactly. That means you know the ratio of side lengths exactly, which lets you solve for x exactly.

Setting that aside, we observe that angle C is greater than angle A, so side AB will be longer than side BC.

3x +15 > 4x +7

8 > x . . . . . . . . . . subtract 3x+7

We also know that the lengths of these sides must be positive. Since BC is the shorter side, we require ...

4x +7 > 0

4x > -7

x > -7/4

So, the allowable values of x are ...

-7/4 < x < 8

<em>More complete solution</em>

If we read the figure correctly, the sum of angles is ...

(2y +12) +(4y +12) +(y -18) = 180

7y +6 = 180

y = (180 -6)/7 = 24 6/7°

Then (in degrees) ...

∠A = 2(24 6/7) +12 = 61 5/7, and ∠C = 4(24 6/7) +12 = 111 3/7

The Law of Sines tells us ...

AB/sin(C) = BC/sin(A)

sin(A)(3x +15) = sin(C)(4x+7)

x(4sin(C) -3sin(A)) = 15sin(A) -7sin(C)

x = (15sin(A) -7sin(C))/(4sin(C) -3sin(A))

x ≈ 6.1872652
