arsen [322]4 years ago
5 0

Answer:

3/7x

Step-by-step explanation:

21yz

--------------

49xyz

We can break this into pieces

21   1        y          z

--- * ---- * ----- *   ----

49    x      y          z

Now we can simplify. canceling the y terms and the z terms

3*7   1         1          1

------ * ---- * ----- *   ----

7*7    x         1          1

Now we can simplify canceling the 7 terms

3         1        

------ * ----

7         x        

We are left with

3/ 7x

I need help finding the formula..
KiRa [710]
X=first week
y=second week
z=third week
t=fourth week

18 more one 2nd week than 1st
x+18=y
x=y-18

3rd week, 4 less than 2 times as second
z=2y-4

4th week, 92

ttal=382

x+y+z+t=382
sub waht we know
x=y-18
y=y
z=2y-4
t=92

y-18+y+2y-4+92=382
conbine line terms
4y+70=382
minus 70 boht sides
4y=312
divide both sides by 4
y=78

A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?​
Likurg_2 [28]

Answer:

Each side is 6 units.

Step-by-step explanation:

The problem is not how to do the question. The problem is how to get your calculator to do the question.

V = s^3

s = ?

V = 216

So what you need is the cube root of 216

s^3 = 216

cube root(s^3) = cube root(216)

s = cube root 216

Your calculator should have a y^x or x ^y key.

Put in 216

Press the y^x key or the x^y key

Put in 0.33333333333

You should get something like 5.999999 which you should round to 6.
