Answer:
Infinitely many solutions
Step-by-step explanation:
Note that 2(2x+3y=12) is 4x+6y=24, which is the first equation. Therefore, by canceling the equations out, you have 0=0, which means whatever one side equals, the other side ALWAYS equals that.
Answer:

Step-by-step explanation:
Hello There!
If you didn't know vertical angles are congruent
That being said we can use this equation to solve for x
40 = 5x
Objective: Isolate the variable using inverse operations
To get rid of the 5 we divide each side by 5
40 / 5= 8
5x/5=x
we're left with x=8
To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct
5(8) = 40
So the answer would be 8
Firstly we need to count what is the difference between both altitudes:
44,000 - 9,000 = 35,000
If a plane descends at a rate of 2,500 feet per minute, then we have to count how many 2,500s fit in 35,000:
35,000 / 2,500 = 14
It means that the jet will reach its cruising altitude in 14 minutes.
Answer:
The answer is 100% for the first one and 50% for the second one.
