Y=10 because on the left X has to equal 30 in order for the angle to be 90 degrees. After that you take the X which is 30 and put it in the equation (2X+3Y) Now the line is a line which means that the angle containing (2X+3Y) must equal 90 like this (2X+3Y)=90 So plug in X [2(30)+3Y]=90 60+3Y=90 subtract the 60 and you get 3Y=30 divide 30 by 3 and you get Y=10 Hope this helped
T = Total cost
V = Amount of visits
T = 25 + 9v Plug in the amount of visits
T = 25 + 9(13) Multiply
T = 25 + 117 Add
T = 142
Lisa will owe $142 .
The expression before simplifying would look like:
(2/3m-11/6) + (5/6m-11/3)
Next you would group common terms and get:
(2/3m+5/6m)+(-11/6-11/3)
In order to combine these fractions. they need to have common denominators and the expression would become:
(2*2/3*2m+5/6m)+(-11/6-11*2/3*2)
(4/6m+5/6m)+(-11/6-22/6)
Now simplifying the expression, you would get:
9/6m+-33/6
or
9/6m-33/6
