Answer:
B=9
Step-by-step explanation:
Solve for b by simplifying both sides of the equation, then isolating the variable.
Hope this helps
Answer:
X=-2
Y=-6
Step-by-step explanation:
Since both equations are already expressed in the simplest form of y, then we equate them to be equal hence
x-4=4x+2
Bringing like terms together
-4-2=4x-x
Solving both sides
-6=3x
Making x the subject then
X=-6/3=-2
Subsrituting the value of x into any of the initial equations
Y=x-4 then y=-2-4=-6
Therefore, the solution is
X=-2
Y=-6
4000. You need to round it to the nearest thousand, which would be the 4 at the start if you break it down into its units. Where from right to left, you have, 1s, 10s, 100s and 1000s. Meaning you need to keep the first digit (unless the hundreds are 500+) and everything after should just be the thousands.
Try using fraction, i think the ans is 28/205 ;)
