Answer:
C. j +2j + 3(2j) = 175
Step-by-step explanation:
Let j represent the amount of money Jim has.
Carroll has twice that amount, so has 2j.
Mike has 3 times the amount Carroll has, so has 3(2j).
The sum of these quantities is 175, so the equation can be written ...
j + 2j + 3(2j) = 175 . . . . . matches choice C
n/4 because all it wants is a number which is expressed by n divided by 4
Is there more to the problem? There isn’t enough information here.
If you add 5x to 2x+2 you will get 7x+2. You would set this equation equal to 80, so it would be 7x+2=80. When you solve this you will get 11.1428571429, which can be rounded to 11, 11.1, or 11.14, whichever you prefer.
Answer:
0.153
Step-by-step explanation:
It has been a long time since I've done this, so I hope it is correct:
cos = adjacent side / hypotenuse
cos x = 13 / 85 = 0.153
