Answer:
y = 1/6
Step-by-step explanation:
direct variation
y =kx
substitute in what we know to find k
1/2 = k*3
solve for k
divide by 3
1/2 /3 = k
1/6 = k
substitute k into the direct variation equation
y = 1/6 x
let x = 1
y = 1/6 *1
y = 1/6
Answer:
Markup= 1.81
Sale price =9.06
Step-by-step explanation:
The markup is the original prices times the markup rate
markup = 7.25 * 25%
= 7.25 * .25
=1.8125
We round this to the nearest cent
=1.81
The new sale price will be the original price + the markup
7.25+1.81
9.06

Answer:
The equation which can be used to find the value of numbers
(x) + (x + 1) + (x + 2) = - 21
Step-by-step explanation:
Let the first no. is = x
Second number = x + 1
Third number = x + 2
The sum of three consecutive numbers = x + x + 1 + x + 2
Given that Three consecutive integers have a sum of –21.
Therefore
(x) + (x + 1) + (x + 2) = - 21
This is the equation which can be used to find the value of numbers.
Multiply -1/2 by -7/3 to get the answer
