Answer:
14.x=-2
21. x=-2
23. x=5
7.x=12
2.x=49
Step-by-step explanation:
I got your back bro:
14. Subtract 7 on both sides. Then divide -16 by 8. x=-2
21. Add 1 on both sides. Divide 18 by -9. x=-2
23. Subtract 24 on both sides, then divide -25 by -5. your answer is x=5.
7. Add 2/5 on both sides. then multiply 2 2/5 by the reciprocal of -1/5. Your answer is x=12
2. Subtract 5 on both sides. Multiply 14 by the reciprocal of 2/7, or 7/2. Your answer is 49.
Good luck!
Answer:
It would cost <em>n</em> people $<em>nd</em> to play Decimal Decisions and $<em>nr</em> to play Ratio Rage. So, it would cost <em>n</em> people $<em>nd</em> + $<em>nr</em>= $2<em>n</em>(<em>d</em> + <em>r</em>).
<em>d</em>= Decimal Decisions and <em>r</em>= Ratio Rage
You didn't give a price for either game, so I just did variables in place of actual cost. Hope this helps!

7cos(x) + 1 = 6sec(x)
7cos(x) + 1 = 6/cos(x)
7cos^(x) + cos(x) = 6
7cos^(x) + cos(x) - 6 = 0
[7cos(x) - 6][cos(x) + 1] = 0
cos(x) = 6/7 , x = arccos(6/7) and
cos(x) = -1, x = 180
0.64,-3.14 I’m not really sure about the -3.14. (Sorry).
