Answer:
$8.50 per hour
Step-by-step explanation:
Alyssa worked 3 hours on Sunday and 4.2 hours on Monday
Total Number of hours Alyssa worked= Number of hours she worked on Sunday+Number of hours she worked on Monday=(3+4.2)=7.2 Hours
Total amount she earned if she is paid in a hourly rate=(Total Number of hours she worked×Money she earns per hour)
Replacing;
Total amount she earned=$61.20, Number of hours she worked=7.2, Money she earns per hour is unknown=M
61.20=7.2×M
Solving for M
(7.2×M)/7.2=61.20/7.2
M=$8.50 per hour
The money she earns per hour=$8.50
I think it is 291,060 square kilometers, i might be wrong
The rate of change is also known as the slope. To easily find the slope of a line, put the equation into slope intercept form by isolating y on one side.
8 + y = 2x
y = 2x - 8
By definition, the rate of change is 2.
