Answer:
The answer to your question is 2C - 9 ≤ - 22
Step-by-step explanation:
I will write the answer step by step
1.- twice a number; let C be the number
2C
2.- The difference of twice a number and 9
2x - 9
3.- At most " ≤ " Use this symbol and not "<" to indicate that number -22 is consider by the inequality.
4.- The inequality is
2C - 9 ≤ - 22
Answer:
33 
%
Step-by-step explanation:
Create a fraction where the of value is on the denominator, then multiply by 100% to change to a percentage, that is
×100%
= 33.3333... × 100% = 33.333... % = 33 % ← exact value
I think................U do 100 = 10 because 100 is the hundreds and the tenths is the 10.
a) As the constants are equal, the situation represents a proportional relationship.
b) The constant of 2/3 cupcakes per minute means that in a minute, 2/3 of a cupcake is made.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the constants for each situation are:
k = 30/45 = (30/15)/(45/15) = 2/3 = 20/30.
Since the constants are equal, the situation represents a proportional relationship.
The constant of 2/3 cupcakes per minute means that in a minute, 2/3 of a cupcake is made.
