X=one type that cost 9
y=one type that cost 8
total books=type1+type2
total books=13
x+y=13
the total cost=cost of each added together
cost of each=number of books times cost per book
total cost=108
9x+8y=108
we have
x+y=13
9x+8y=108
solve for x and y
multiply first equation by -8 and add to first equation
-8x-8y=-104
<u>9x+8y=108 +</u>
x+0y=4
x=4
subsitute
x+y=13
4+y=13
minus 4
y=9
4 of the $9
9 of the $8
thats how to solve
Let no. of adult tickets be x and senior citizen tickets be y.
x + y = 556
22x + 12y = 8492
Solving by simultanous equations,
x = 182 adult tickets
y = 374 senior citizen tickets
Answer:
<h2>The answer is 2</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(82, −96) and (87, −86)
We have
We have the final answer as
<h3>2 </h3>
