The solution of system of equations is: x = 1.6 and y = 1.2
Step-by-step explanation:
Given equations are:
Putting 
in equation 2
Putting x = 1.6 in equation 2
Dividing both sides by -3
Hence,
The solution of system of equations is: x = 1.6 and y = 1.2

4 + y = 9.5
subtract 4 from both sides :
4 + y - 4 = 9.5 - 4
y = 5.5
Answer:
Jack is evil.
Step-by-step explanation:
Jack wasn't very smart, one-day jack made a science experiment to increase the temperature of frogs 2 fold every week starting from 2 degrees Celcius, the graph shows how much he cooked the poor frog in the weeks that sadly, followed.
(in case you don't know fold just means multiplied by that much so 20k$ going 10 fold is 200k$)
Answer:
9.47
Step-by-step explanation:
This problem calls for calculating the unit cost in each case and then comparing the unit costs.
$1.79
---------- = $0.09/oz
20 oz
Noting that 1 lb = 16 oz,
$2.59
---------- = $0.14
18 oz
$1.79 for 20 oz is definitely the better buy (less expensive) when compared to $2.59 for 18 oz.
