Answer:
Constant of proportionality(X:Y) = 1:6
Step-by-step explanation:
Given:
X- 5, 6, 7, 8, 9
Y- 30, 36, 42, 48, 54
Find:
Constant of proportionality
Computation:
X/Y = 5/30 = 6/36 = 7/42 = 8/48 = 9/54
X/Y = 1/6 = 1/6 = 1/6 = 1/6 = 1/6
So;
Constant of proportionality(X:Y) = 1:6
Hi there!
To find the total fraction of the class that selected both marigolds and tulips, we need to add the two fractions together.
1/3 + 1/2 = 2/6 + 3/6
2/6 + 3/6 = 5/6
Hope this helps!

Explanation:</h2>
Here we have to solve a system of linear equations in three variables. Let:
x: Cost of pens
y: Cost of pencils
We know that:
- Bailey buys 2 pens and 6 pencils and spends a total of $7.00. So:
- Jeremiah buys 3 pens and 5 pencils and spends a total of $7.50. So:
Multiplying eq1 by 3 and eq 2 by -2:
Then adding these two resultant equations:
How much will Maggie spend to purchase 4 pens?
Each pen costs $1.24, so 4 pens will cost:
You have to use the y=mx+b formula to find the equation
