Answer:
x=4
Step-by-step explanation: So you do 2x plus 1x which is 3x. Then you divide both sides by 3 which leaves you with x=4. Thats your answer. <3
Answer:
RP: x equals 0
JH: x equals -11
EG: x equals 9
This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300
In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2
Answer:
Step-by-step explanation:
Given
Quadrant III
Required
Determine 
We have:
We know that:
This gives:
Collect like terms
Take LCM and solve
Take the square roots of both sides
Sin is negative in quadrant III. So:
Calculate 
We have:
So:
Rationalize
So, we have:
Substitute:
Take LCM
