9x-5y=11
<span>Move all terms containing x to the left, all other terms to the right.
now add 5y to each side and now it should look like this:
</span><span>9x + -5y + 5y = 11 + 5y
Now divide each side by 9 and the answer is....
</span><span>Simplifying
x = 1.222222222 + 0.5555555556y</span>
Answer:
1400 is the final altitude
Step-by-step explanation:
Since Lucy descended for four minutes at a rate of 200 feet per minute, we can find how much altitude she lost in four minutes by multiplying 200 by 4. So Lucy descended 800 feet.
To find the final altitude, we take how much she descended and take it away from her starting altitude. So 2200-800 = 1400 feet.
Answer: x=12
Step-by-step explanation:
You start with:
The segment PQ is half of PR, so to make both sides equal the PQ side must be doubled.
Then all x-values should be put on one side of the equation.
Combine like terms.
Then simplify.
Answer:
-26= -9x + 10
-26 - 10= -9x
-36=-9x
-36:(-9)=x
4=x
Step-by-step explanation:
1. you pass +10 to the left in minus
2. you resolve what you've got on the left
then you pass the multiplying -9 to the left dividing
