Answer:
x= no solution
Step-by-step explanation:
4x-2+x=-2+2x
We first add 4x+x on the left side.
5x-2=2+2x
We then add 2 to both sides.
5x=2x
The answer is no solution because we got no answer out of the equation.

Answer:
{Segments, Geometric mean}
{PS and QS, RS}
{PS and PQ, PR}
{PQ and QS, QR}
Step-by-step explanation:
The three geometric mean relationships are derived from the similarity of the triangles the similarity proportions can be written 3 ways, each giving rise to one of the geometric mean relations.
short leg : long leg = SP/RS = RS/SQ ⇒ RS² = SP·SQ
short leg : hypotenuse = RP/PQ = PS/RP ⇒ RP² = PS·PQ
long leg : hypotenuse = RQ/QP = QS/RQ ⇒ RQ² = QS·QP
I find it easier to remember when I think of it as <em>the segment from R is equal to the geometric mean of the two segments the other end is connected to</em>.
__
segments PS and QS, gm RS
segments PS and PQ, gm PR
segments PQ and QS, gm QR
Answer:
z = 20
Step-by-step explanation:
subtract 19z from 20z, and add 8 to 12. you will be left with 20 = 1z. Divide 1 by 20 and you will have Xz =20.
I hope this helps!
Answer:
Step-by-step explanation:
Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.
For UK, Number of Samples
For France, Number of Samples
For Spain, Number of Samples
For Italy, Number of Samples
The completed table therefore is:
You just substitute in what x equals. ex. x=16, x-7 : 16-7=9.
x-7
1. x= -8; -8-7= -15
2. x= -11; -11-7= -18
3. x=16; 16-7= 9
