Answer:
x = 2/5
Step-by-step explanation:
Given:
7 + 5x = 3(y-2)
Rearrange this equation such that x is expressed in terms of y
7 + 5x = 3(y-2) (expand right side)
7 + 5x = y(3)-2(3)
7 + 5x = 3y-6 (subtract 7 from both sides)
5x = 3y - 6 - 7
5x = 3y - 13
we are given the y-value of the coordinate pair (? , 5)
simply substitute y=5 into the equation above
5x = 3y - 13
5x = 3(5) - 13
5x = 15 - 13
5x = 2 (divide both sides 5)
x = 2/5
Answer:
2916
Step-by-step explanation:
1.5 feet is 1 foot 6 inches, or 18 inches
volume is height * length * width, so 18 * 9 * 18 = 2916
Answer: 600
Step-by-step explanation: 6!x5!= 86400| 4!x3!= 144| 86400/144= 600
Hope it’s right!
Answer:
20%
10%
0.5
5%
Step-by-step explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Percentage change in price = (1.2/1) - 1 = 20%
Percentage change in quantity demanded = 450/500 - 1 = 10%
