Answer:
D, B, C, A
Step-by-step explanation:
Solve the equations by combining like terms, isolating the variable, and dividing the equation by the coefficient of the variable.
Doing this, the first equation should be 2, the second equation should be -2, the third equation should be -1, and the last equation should be -6.
Then, we can order them.

There seems to be a typo. You wrote 1313, but I'm assuming you meant to say the fraction 1/3. If this assumption is correct, then continue with the rest of the solution. If the assumption is not correct, then ignore what I wrote below and please provide clarification of what the "1313" should represent. Thank you.
----------------
B = your brother's age
S = your sister's age
Y = your age
All of these ages are current present day ages.
---------------
"your brother is 1/3 your age" so B = (1/3)Y or B = Y/3.
"Your sister is 6 years older than your brother" so S = B+6
"Your sister is 10 years old" so S = 10.
---------------
S = B+6
B+6 = S
B+6 = 10 ... plug in S = 10
B+6-6 = 10-6 ... subtract 6 from both sides
B = 4
Your brother is 4 years old.
---------------
B = Y/3
Y/3 = B
Y/3 = 4 .... plug in B = 4
3(Y/3) = 3*4 ... multiply both sides by 3
Y = 12
<h3>Answer: Your age is 12 years old.</h3>
note: This answer hinges on assumption that the "1313" should be "1/3".

Answer:
3. 2.5
4. $5 per candy bar
5. You mowed 6 lawns
6. 15.66 is the number
7. 13 weeks
8. 135 students came
9. 12
Step-by-step explanation:
3. 25+7= 32.
81/32= 2.5
4. 23-3= 20
20/4= 5
5. 155-35=120
120/20=6
6. 10-4 = 6
94/6=15.66
(not 100% sure about this one)
7. 200-161=39
39/3=13
8. 975-300=675
675/5=135
9. 36-12=24
36/3= 12
(not 100% sure about this one)
Bonus: Sorry I don't know
I hope I can help! Also next time do each question one by one so other people can answer and not answer all of them if they don't know one.
