Answer:
x=18
Step-by-step explanation:
Hey There!
So if you did not know all of the angles in a triangle will add up to equal 180
So we use the equation
180=2x+3x+5x
and solve for x
step 1 combine like terms
2x+3x=5x
5x+5x=10x
so now we have
180=10x
step 2 divide each side by 10
180/10=18
therefore x = 18
hope this helps and if you have any more questions feel free to ask :)
1. Multiply each equation so they end up with the same coefficient
2. Subtract your second equation from the first
3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)
4. Substitute the variable you found in the least step into one of the other equations and find a second variable.
5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))
I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)
Answer:
Percent increase = 60%
Percent increase with baggage = 83%
Step-by-step explanation:
Given that:
Old price of the ticket = $210
New price of the ticket = $335
Increase amount =335-210 = $125
Percent increase = 
Percent increase = 
Percent increase = 59.52% = 60%
Additional charges = $125+$50 = $175
Percent increase = 
Percent increase = 83%
Hence,
Percent increase = 60%
Percent increase with baggage = 83%
Answer: 0.25 feet
Step-by-step explanation:
Given: Jonathon has paper strips that are all equal in length.
Let x be the length of each paper strip.
Since John lines them up end to end, the length of the line of paper strips= 3 feet
Also total strips used= 12
Therefore, length of line of strips=

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.
