Answer:
(a)
system of equations are
(b)
Graph is attached
(c)
Sam earned =$200
Kevin earned =$225
Step-by-step explanation:
Let's assume
's' for the amount Sam earned
'k' for the amount Kevin earned
(a)
Together they earned a total of $425
so, we get
Kevin earned $25 more than Sam
so, we get
so, system of equations are
(b)
now, we can draw graph
(c)
intersection point will be our solution
and we got intersection point as
(200, 225)
so,
s=200
k=225
To get your answer:
9 times 5 times two= 90
9 times 7.5 times two= 135
5 times 7.5 times two= 75
then add all of them together and you will get the surface area
90+135+75=300
you should have an answer of 300 feet²
Answer:
700/383
Step-by-step explanation:
Answer:
5 degrees
Step-by-step explanation:
We are given that during a science experiment
The temperature of a solution in a beaker 15 degrees below zero
The temperature of solution in a beaker 2 was opposite of the temperature in beaker 1
We have to determine the temperature of beaker 2.
It mean temperature of beaker 1 solution=-5 degrees
According to question
Temperature of beaker 2 solution =5 degrees
Hence, the temperature of solution in a beaker 2=5 degrees
