2x+4x+10+6x-10=180 because all the angles of a triangle equal to 180 so u add up all the angles and set to 180. and x equals 15.
Answer:
3.5 ft
Step-by-step explanation:
I did this by making 7/10 in a percent, 70% because I work better with percents. 70% of 5 is 3.5
Answer: No solutions
Step-by-step explanation:
There are no solutions to 0 = x² - x + 1.
[Method One]
We can solve this by rewriting the equation, but it is quicker to graph it when there are no solutions. See attached.
[Method Two]
I said we can solve this by solving an equation, here it is. We will use the quadratic formula since the equation given is already in the proper form.



-> Negative numbers don't have real square roots, so there is no solution
Okay. Mainly for these questions, we have to write out equations.
1. For the vacation days given in the U.S., that equation would be 25-n, because the U.S. gets fewer days than the Japanese worker does.
Equation: 25-n
2. The equation for this one would be 26s, because there are 26 grams of protein for each cup of cottage cheese. To find out the total amount of protein for all of the cups together, that equation works work out.
Equation: 26s
I'm guessing, you substitute j with 12 and then you would have 12/4 and that would be 3
