This is quite easy if you follow steps:
lets start by subtracting the whole numbers
2-2=0
9/10-1/3
first make the denominator same,
lets keep it 30, now change numerators
27/30-10/30
=17/30
Answer:
56 chairs
Step-by-step explanation:
856+700=1556 <--- expected count
chairs set up= 1500
1556-1500= 56 more chairs
You need to note first two things.
1. The function f(x) need to be a continuous function on [-3,-1] (indeed f(x) is a polynomial function, is continuous on every real number x)
2. Take the closed interval [-3,-1]
Now, evaluate f(-3) and f(-1).
So, we have f(-3) < 0 and f(-1). So, 
, then by the Intermediate Value Theorem, there exist 
such that 
.
Answer:
$13.50
Step-by-step explanation:
The total amount spent $80.50 would be equal to the sum of the price of the ticket bought by the 6 individuals
total cost of the tickets for the 2 younger children = $12.50 x 2 = $25
let the price of each ticket for the three older children be represented by x. the total price of the 3 tickets would be 3x
$80.50 = $25 + 3x + 15
Collect like terms and solve for x
$40.50 = 3x
x = $13.50
