Do you have a protractor? If so, use it and place the center whole, that is located at the bottom, and place it on the dot of the angle. where the arrow hits, is your angle degree. You should be able to identify the angle type.
Let me see if I can decipher that :P
3/(3x)+1/x+4=10/(7x) first we need to make all terms have a common denominator of 21x...
(21+21+84x)/(21x)=30/(21x) multiplying both sides by 21x leaves you with
21+21+84x=30 combine like terms on left side
42+84x=30 subtract 42 from both sides
84x=-12 divide both sides by 84
x=-1/7

Step-by-step explanation: there is 4 girls and $24 they split it equally so you would do 24/4 and that gives you 6. Then it says Mrs. Day gave each girl $2 so then you add 6+2 and then you get 8.
