Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55
Answer:
x = -6
Step-by-step explanation:
You can insert the second equation in for the y-variable in the first equation
x + 4(2x+14) = 2
The next step is to distribute the 4
x + 8x + 56 = 2
Then we combine like terms
9x + 56 = 2
Subtract 56 from both sides
9x = -54
Divide by 9 on both sides
x = -6
Answer is 5 hours
Explained
I divided 17,700 by 60 seconds to get minutes
Then I divided by 60 minutes to get hours
4.916 hours rounded to 5 hours
Hello.
In order to solve this equation, we need to isolate the variable (in this case, the variable is x)
The first step is to use the Distributive Property and distribute 3:


Now, add 3 to both sides:



Now, subtract 2x from both sides:


Therefore, the answer is

I hope it helps.
Have a nice day.

Answer:
75 degrees since it has 2 equal sides.
