f12. Anne is seven years older than her brother, Brandon. Anne is 23. Which equation below could you solve to determine Brandon’s age? (Let A represent Anne’s age and let B represent Brandon’s age.)
AA + B + 7 = 23
BB = 7 + 23
CA + B = 23
D23 = B + 7
EA = 23 + 7
F23 = A + 7
d13. Last Friday, the Cougars beat the Tigers in basketball by 17 points. The Tigers scored 62 points. Which equation below could you solve to find out how many points the Cougars scored? (Let C represent the Cougars' score and let T represent the Tigers' score.)
AT + 17 = 62 + C
BT + C = 62
CC – 17 = 62
DTC = 62
EC = 62 - T
FT - 17 = 62
e14. Of the 62 points scored by the Tigers, Mary scored 28 points, which is twice as many points as Lashawna scored. Which of the following equations describes the number of points scored by Lashawna? (Let M represent the points Mary scored and let L represent the points Lashawna scored.)
A2L = 62 - M
BM/2 = 62L
CM - 2L = 28
D2L = 28
EL = 62 - 2M
FM - 2 = 28
b15. Joey owns a small bakery and today Phoebe has ordered 100 cookies. If Joey boxes the cookies by the dozen, which of the following equations describes how many boxes of cookies Phoebe will have? Let b represent the number of boxes. (HINT: All of the cookie boxes are not necessarily full.)
A100 = b/12
B12b + 4 = 100
C12b = 100 – 4
D100/b = 12
E(100-4)/12=b-1
F12 + b = 100
d16. As Gary is preparing to move, he notices that several of his smaller packed boxes will fit inside a large one. If each of the smaller boxes is a cube with side length 9 inches, and the volume of the larger box is 19683 cubic inches, which equation could be used to determine n, the number of smaller boxes that will fit inside the larger one?
A19683/9 = n
B19683 = n * 81
C19683 = 729n
D19683 - 729 = n
E19683 * 9 = n
F19683 = 9n
b17. Newton’s second law states that the amount of force acting on an object is equal to the product of the mass of the object and the acceleration of the object (F = ma). Which of the following equations is the correct way to solve this equation for m?
Am = Fa
Bm = F - a
Cm = F + a
Dm = a/F
Em = 1/(Fa)
Fm = F/a
a18. The formula F = C(9/5) + 32 may be used to convert a temperature in degrees Celsius to degrees Fahrenheit. How could this equation be rearranged to convert a temperature in degrees Fahrenheit to degrees Celsius?
AC = (5/9)(F - 32)
BC = 32F - 9/5
CC = (5/9)F + 32
DC = (9/5) - 32F
EC = 32F - (9/5)
F5C = F/9 -32
d19. Malachi is an artist with unrecognized talent. As he plans to create the masterpiece that will cause him to be discovered, he realizes that he needs more paint. He will need to purchase several new colors, each of which costs $7.50. In addition, he will have to pay 6% sales tax. Which equation below could Malachi use to decide how many colors he can buy for $45.00?
A(7.50)(6)c = 45.00
B(7.50)c = 45.00(1.6)
C(7.50 + 0.06)c = 45.00
D(7.50)(1.06)c = 45.00
E(7.50)c = (45.00)(0.06)
F(7.50)c = (45.00)(1.06)
a20. At a local candy store, Malcolm purchased some 25-cent candies and some 30-cent candies. He spent a total of $4.75. Which equation below describes the number of each type of candy he bought?
A25x + 30y = 4.75
Bx + y = (4.75)/(0.25 + 0.30)
C25 + x + 30 + y = 475
D0.25/x + 0.30/y = 4.75
Ex + y = 4.75 - 0.25 - 0.30
F0.25x + 0.30y = 4.75

uhh i did give me answers. "please check my homework
(c)1. Solve 3x – 19 = 2
Ax = -17
Bx = -17/3
Cx = 7
Dx = -51
Ex = 20
Fx = 18"
do you see the c infront of the number? that's where all my answers are. i put it in parenthesis.

Welcome back, Whitney. I have to leave for work but I checked as many as I could. Hopefully someone else can check the rest or I can check the rest later. I checked up to 12. They are all right except 4, 6, 7, 12 (5 I'm not sure about).
13, 14 are wrong..I'm not going to check anymore..If you need help (step by step) on one or two problems, please re-post. It seems that you are just guessing.
Sorry, I did not notice the letter in front of the number of the problem. I will start from the bottom to finish off the responses.
20. Right.
19. Right.
18. Right.

Yall are wrong for these replies. Were not wanting the answers we really need you help. the only one I could really do is # 1. By the way I can not cheat because my teacher asks us to show our work
