Answer:
Step-by-step explanation:
2x+y=8x-y=4
First solve take all x variable to one side and all the y on one
y+y=8x-2x=4
2y=6x=4
Solve for x solve for y
6x=4 2y=4
x=4÷6 y=2
x=4/6
Answer:
x = 1/4
Step-by-step explanation:
Solve for x:
1 - 2 (1 - 2 x) = 0
Hint: | Distribute -2 over 1 - 2 x.
-2 (1 - 2 x) = 4 x - 2:
4 x - 2 + 1 = 0
Hint: | Group like terms in 4 x - 2 + 1.
Grouping like terms, 4 x - 2 + 1 = 4 x + (1 - 2):
4 x + (1 - 2) = 0
Hint: | Evaluate 1 - 2.
1 - 2 = -1:
4 x + -1 = 0
Hint: | Isolate terms with x to the left hand side.
Add 1 to both sides:
4 x + (1 - 1) = 1
Hint: | Look for the difference of two identical terms.
1 - 1 = 0:
4 x = 1
Hint: | Solve for x.
Divide both sides by 4:
Answer: x = 1/4
Answer:
X=1
POQ= 1/3x+1/3= 1/3(1)+1/3=2/3
QOR= 2x +4/3= 2(1)+4/3= 10/3
POR= 5x-1= 5(1)-1= 4
Step-by-step explanation:
The answer is A when you multiply a negative number you change the sign.

Answer:
(b) 2√14
Step-by-step explanation:
The geometric mean theorems applicable to this geometry are ...
q = √(4·(4+10))
q = 2√14
__
<em>Other unknowns</em>
r = √(10·(10+4)) = 2√35
s = √(10·4) = 2√10
