is 4/20 and 3/12 proportional
Answers
Answer:
no it is not
Step-by-step explanation:
you would have to get a common denominator which would be 60 so 12 times 5 is 60 and 20 times 3 is 60
then you multiply 4 by 3 and thats 12 and 3 times 5 is 15 so no they arent perportional
Answer Explanation: Simply do cross multiplication. If the numbers are not the same number, the ratios are not proportional. 48 does not equal 60. SEE IMAGE

7v- 5 ≥ 65 or -3v - 2 ≥ -2
Answers
The result if the inequality expressions are v ≥ 10 and v < 0
Given the following inequality expression
7v- 5 ≥ 65 or -3v - 2 ≥ -2
Solve the inequality individually
7v - 5 ≥ 65
Add 5 to both sides
7v - 5 + 5 ≥ 65 +5
7v ≥ 70
v ≥ 70/7
v ≥ 10
For the inequality-3v - 2 ≥ -2
Add 2 to both sides
-3v - 2 + 2≥ -2 + 2
-3v ≥ 0
v < 0
Hence the result if the inequality expressions are v ≥ 10 and v < 0

A local hamburger shop sold a combined total of 575 hamburgers and cheeseburgers on Sunday. There were 75 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?
Answers
Answer:
250 Hamburgers
Step-by-step explanation:
575 is total
Hamburger is x
Cheesburgers is (x-75) as it is 75 less than the number of hamburgers
x + (x-75) = 575
2x -75 = 575
2x = 500
x = 250

Use the scenario and table to determine which statements are true. Check all that apply.
Armand and Jill will each travel the same distance to meet.
Armand and Jill will travel the same amount of time to meet.
The equation used to find the time, t, it will take for them to meet is 50t + 60t = 247.5.

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 25 pounds and each large box of paper weighs 70 pounds. A total of 21 boxes of paper were shipped weighing 1110 pounds altogether. Write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped. Define the variables that you use to write the system.
Answers
Answer:Number of small boxes shipped = 8
Number of large boxes shipped = 13
Step-by-step explanation:
Step-by-step explanation:
Let x be the number of small boxes and let y be the number of large boxes
According to the first statement, a total of 21 boxes were shipped
Equation 1 will be:
x+y=21
According to 2nd statement, the total weight was 1110 and we know the weight of one small box is 25 and large box is 70
Equation 2 will be:
25x+70y=1110
Use the substitution method for solving the equation
Putting the value of x in equation 2
25(21-y) +70y =1110
525-25y+70y = 1110
45y = 585
Y=13
Putting the value of y in equation 1
x+13 = 21
X = 8
Number of small boxes shipped = 8
Number of large boxes shipped = 13
