Un = 5 x 21 What is the answer to this problem?

siniylev [52]

Answer:

N = 105/u

U = 105/n

Step-by-step explanation:

Let's solve for n.

un=(5)(21)

Step 1: Divide both sides by u.

nu/u = 105

un = 105/u

__________________________

Let's solve for u.

un=(5)(21)

Step 1: Divide both sides by n.

nu/n = 105/n

u = 105/n

Answer:

Step-by-step explanation:

x/7 - 3/8 = 27/56

Multiply through by 56 , as 7 * 8 = 56 we have:

8x - 3*7 = 27

8x = 27 + 21 = 48

x = 6.

Describe in words the region of R3 reperesented by the equations or inequalities x2+y2+z2≤3

Vaselesa [24]

Answer:

The region represented by the equation is a full sphere of radius √3 centered in the origin of coordinates.

Step-by-step explanation:

In a plane xy, the equation that represents a circle with center in the origin, of radius r is

$x^2+y^2=r^2$

in R³, or a space xyz, we can represent a sphere with its center in the origin, and of radius r, with the equation

$x^2+y^2+z^2=r^2$

So, in this problem we have that

$3=r^2$

which means that the sphere has a radius of √3.

Finally, our equation is an inequality, and the sphere is equal to, and less than, the calculated radius.

Therefore, the sphere is "full" from the surface to its center.

Five times the larger number is 11 more than three time the smaller number. Also three times the smaller is 16 less four times t

alisha [4.7K]

Let the larger number be w and the smaller number be k;
5w-11=3k
3k+16=4w
Reorganizing the equations;
5w-3k=11
4w-3k=16
Subtracting equation 2 from equation 1:
w=-5
Replacing value of w in equation 1;
5(-5)-11=3k
-25-11=3k
3k=-36
k=-12
The numbers are -5 and -12
