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.
17. Wrong, you need to divide rather than subtract.
16. Wrong, you need to divide rather than subtract.
15. Wrong, you need to divide rather than subtract.
To check your homework, we need to solve the given equations and compare the answers to the options provided. Here are the step-by-step solutions:
c1. Solve 3x – 19 = 2
To solve for x, we need to isolate the variable.
Adding 19 to both sides: 3x - 19 + 19 = 2 + 19
Simplifying: 3x = 21
Dividing both sides by 3: (3x)/3 = 21/3
Simplifying: x = 7
The answer is Cx = 7.
b2. Solve 4x + 12x = 62 + 4(11)
To simplify the equation, we combine like terms on each side.
Simplifying the left side: 4x + 12x = 16x
Simplifying the right side: 62 + 4(11) = 62 + 44 = 106
Now we have: 16x = 106
Dividing both sides by 16: (16x)/16 = 106/16
Simplifying: x = 6.625 or x = 6 ⅝
None of the given options match the answer. The equation seems to be incorrect or there may be a mistake in the options.
e3. Solve 8x – 7 = x + 10
To solve for x, we need to isolate the variable.
Subtracting x from both sides: 8x - x = x + 10 - 7
Simplifying: 7x = 3
Dividing both sides by 7: (7x)/7 = 3/7
Simplifying: x = 3/7
The answer is Bx = 3/7.
c4. Solve 4(5x – 9) = -2(3x + 7)
To simplify the equation, we distribute the coefficients.
Expanding the left side: 4 * 5x - 4 * 9 = 20x - 36
Expanding the right side: -2 * 3x - 2 * 7 = -6x - 14
Now we have: 20x - 36 = -6x - 14
Adding 6x to both sides: 20x + 6x - 36 = -6x + 6x - 14
Simplifying: 26x - 36 = -14
Adding 36 to both sides: 26x - 36 + 36 = -14 + 36
Simplifying: 26x = 22
Dividing both sides by 26: (26x)/26 = 22/26
Simplifying: x = 11/13
The answer is Ax = 11/13.
f5. Solve d = m/v for m
To solve for m, we need to isolate the variable.
Multiplying both sides by v: d * v = (m/v) * v
Simplifying: dv = m
The answer is Fm = d * v.
a6. Solve V = lwh for w
To solve for w, we need to isolate the variable.
Dividing both sides by lh: V/(lh) = (lwh)/(lh)
Simplifying: V/(lh) = w
The answer is FW = V/(lh).
d7. Solve A = ½bh for h
To solve for h, we need to isolate the variable.
Dividing both sides by 1/2b: A/(1/2b) = (1/2bh)/(1/2b)
Simplifying: 2A/b = h
The answer is Bh = 2A/b.
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.)
The correct equation is CA + B = 23.
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.)

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.)
The correct equation is CM - 2L = 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.)
The correct equation is 12b + 4 = 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?
The correct equation is B19683 = n * 81.
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?
The correct equation is F = ma.
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?
The correct equation is AC = (5/9)(F - 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?
The correct equation is F(7.50)c = (45.00)(1.06).
