If x+4/4 = y+7/7 then x/4=___

Mathematics
1 answer:
muminat3 years ago
4 0
Please, enclose those binomials x+4 and y+7 inside parentheses:

(x+4) / 4 = (y+7) / 7.  Find (x/4).

Let's solve the above equation for x:

x+4 = 4(y+7)/7.  Then x = 4(y+7) / 7   -   4

Last, divide all 3 terms by 4:            x/4 = (y+7) / 7 - 1   (answer)
                                                         
                                                      y + 7 - 7
You could also type this as x/4 = ------------- = y/7
                                                           7

Calculate the length of the diagonal of a rectangle whose sides measure : (a) 12 meters and 48 meters (b) 11 centimetres and 60
Serggg [28]
When solving this problem, you need to imagine the diagonal line through the rectangle. This makes two triangles which you can use the pythagorean theorem for. 12 squares plus 48 squared equals 2,448. Find the square root of that at it will be your answer (I don’t have the time to figure it out). 11 squared plus 60 squared is 3,712. Square root tbd... add the label and you’re finished!

Find the surface area of this cube. Be sure to include the correct unit in your answer.
NikAS [45]
Are the dimensions 8yd x 8yd x 8yd? If so this is how you do:

First calculate the area or one side. Then multiply it by 6 as all the sides of the cube have the same area.

Side area = 8yd x 8yd = 64yd^2

Surface area = 6 x 64yd^2 = 384yd^2

What is the frequency of the graph of y = 1/3 sin(2x)?
vovangra [49]

Given:

The sine function is:

y=\dfrac{1}{3}\sin (2x)

To find:

The frequency of the graph of given function.

Solution:

If a sine function is defined as:

y=A\sin(Bx+C)+D

Then, the frequency of the sine function is:

f=\dfrac{B}{2\pi}

We have,

y=\dfrac{1}{3}\sin (2x)

Here, B=2. So, the frequency of the given function is:

f=\dfrac{2}{2\pi}

f=\dfrac{1}{\pi}

Therefore, the correct option is D.

Solve the inequality. Explain all steps and identify the properties used. 3a-4<_ 5
Ierofanga [76]
Well, you want to solve for a. You first add the 4 to both sides. 
3a-4<5
3a<9
Then you want to get a by itself so you divide both sides by 3. Since the 3 is positive you don't have to worry about switching the sign. It stays this way <

After you divided both sides by 3 you get a<3

I don't know how to solve this.Please help!<br> 3^x=2
svet-max [94.6K]
So 3^X= 2 is an exponential equation. The inverse of an exponential in ln. so take ln of both sides to solve.

Another way is to change the exponential into a log equation
So that would be log with base 3 to the power of 2 equals x.
