The commission of selling each iPhone is $30 and the commission of selling each iPad is $20. If you one day sold 4 more iPhones
sineoko [7]
<span>lets assume number of iphones sold = a number of ipads sold = b i sold 4 iphones more than ipad that becomes a = b+4 then the equation of total commission becomes 30a+20b = 520 substituting a =b+4 in the above equation 30(b+4)+20b = 520 30b+120+20b = 520 50b =520-120 50b = 400 b = 400/50 b=8 number of iphones i sold = a = b+4 = 8+4 = 12 number of ipads i sold = 8 so i sold 12 iphones and 8 ipads to earn the commission of $520</span>

Is (5,1) a solution to the equation 2x-y=11? Explain
grigory [225]
This is simple. Coordinate form is (x,y) so you would just plug in your values. 

2(5)-(1)=11

10-1 does not equal 11, so no it is not a solution.

42. The diagram represents a ramp in the shape of a right triangle and the lengths
oee [108]

The length of the ramp is  61 feet.

<h3>What is the length of the ramp?</h3>

In order to determine the  length of the ramp, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where a = length

b = base

c = hypotenuse

√11² + 60²

√121 + 3600

√3721

= 61 feet

Please find attached the image of the ramp. To learn more about Pythagoras theorem, please check: brainly.com/question/14580675
