Answer:
and 
Step-by-step explanation:
First, we are told "sum of 5 times one number, x, and 4 times a second number, y, is 75":
(1)
Then, we are told "he sum of the two numbers is 18":
(2)
At this point we have our system of equations and now we are able to find the values of
and
.
So, let's begin by isolating
from (2):
(3)
Substituting (3) in (1):
(4)
Finding
:
(5) This is the value of 
Substituting (5) in (1):
(6)
Finding
:
(7)
(8) This is the value of 
Answer:
w = 60
Step-by-step explanation:
the midsegment SU is half the measure of side RV , then
SU =
RV , so
w - 30 =
w ( multiply through by 2 to clear the fraction )
2w - 60 = w ( subtract w from both sides )
w - 60 = 0 ( add 60 to both sides )
w = 60
That is a tenth degree equation.
The degree of an equation is the highest power it contains.
