Answer:
A. The constant ratio of y/x is 12/5
Step-by-step explanation:
The ratio of y to x is constant which is 12/5. Hence option A is the correct option.
What is a constant?
The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings: a constant, clearly defined number or another immutable mathematical object.
Given table is
x y
5/6 2
25/6 10
125/6 50
625/6 250
When x = 5/6 and y = 2:
x/y = (5/6)/2 = 5/12
∴y/x = 5/12
When x = 25/6 and y = 10:
x/y = (25/6)/10 = 25/60 = 5/12
∴y/x = 5/12
When x = 125/6 and y = 50:
x/y = (125/6)/50 = 125/300 = 5/12
∴y/x = 5/12
When x = 625/6 and y = 250:
x/y = (625/6)/250 = 625/1800 = 5/12
∴y/x = 5/12

Refer to the table shown. If the pattern continues what algebraic expression can be used to find the plants height for any month? What will be the plants height at 12 months?
Answers
Answer:Answer is 36 inches high.
Step-by-step explanation:
Each term is 3 times the number of months. So, the
expression is 3n.
3 3(12) n
Replace n with 12.
36
At the end of 12 months, the plant will be 36 inches high.
If you multiply one month by 12, you get 12 months.
Now if the plant grows 3 inches each month, and you are trying to find it’s height at 12 months multiply 3 and 12.
3 x 12 = 36 inches, which is your answer.
The average daily temperature in a city is 55° in May. The average daily temperature in that same city is −3° in December. Which of the following represents the difference in degrees of these average temperatures? |55| − |−3| = 52° |55| + |−3| = 58° 55|−3| = 52° |−55| − |−3| = 58°

A theater sold 85% of the tickets for a
play. If 170 tickets were sold, how many
tickets were originally put up for sale?
Answers
Answer:
200 tickets.
Step-by-step explanation:
85% = 85/100 = 0.85
170/0.85 = 200
= 200
Check:
200*0.85 = 170
Answer: hope this helps ♡
200 tickets were originally put up for sale.
Step-by-step explanation:
85% = 170
(we divide 85 and 170 by 85)
1% = 2
(now multiply 1 and 2 by 100)
100% = 200
(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)
how can you use a mental math and the inverse property of addition to find the sum [5.5 + (-2.3)] + (-5.5 + 2.3)?
Answers
Answer: it is 0
Step-by-step explanation:
[5.5+(-2.3)] + (-5.5+2.3)
We can multiple (-5.5+2.3) by -1 so that it equals the first expression
[5.5+(-2.3)] + (-1)[5.5+(-2.3)]
Then, we change the + to -
[5.5+(-2.3)] - [5.5+(-2.3)]
since we are subtracting the same value, the answer is 0.

Every New Year's Day, Jennifer brings 13 candies for each of her grandchildren and 20 more candies for the adults to share.
Let g represent the number of Jennifer's grandchildren and c represent the total number of candies she brings.
Find the value of c when g=9.
Answers
Answer:
We can use the given information to set up a system of two equations:
c = 13g + 20
c - 13g = 20
The second equation is obtained from the first equation by subtracting 13g from both sides.
To solve this system, we can use substitution.
First, we solve the second equation for c.
c = 20 + 13g
Then, we substitute this expression for c into the first equation.
20 + 13g = 13g + 20
Then, we simplify.
20 = 20
So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

someone help me pls:(
Answers
Answer: Ratios form a proportion if they are equal when cross-multiplied.
1/4 and 3/12
Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.
So they are equal and form a proportion.
54/10; 81/15
Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.
So they are equal and form a proportion.
18/24; 15/20
Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.
So they are equal and form a proportion.
Hence, all the ratios mentioned above form a proportion.
