Seems like the price goes up each year, so I'd say 7 years
Answer:
Step-by-step explanation:
Let x represent the number of rides Beth rides and y represent the number of exhibits she views.
Each ride costs $7 to ride and each exhibit costs $3 to view.
This means that x rides will cist x × 7 = $7x
Also, if she views y exhibits, the cost will be y × 3 = $3y.
Total cost of x rides and y views will be 7x + 3y
if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98
The required expression will be
7x + 3y </=8
Answer:
D
Step-by-step explanation:
Given
x = 6 - x² ( subtract 6 - x² from both sides )
x² + x - 6 = 0 ← in standard form
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)
The factors are + 3 and - 2, since
- 3 × 2 = - 6 and 3 - 2 = + 1, thus
(x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Sum of solutions = - 3 + 2 = - 1 → D
Equation :
[x(x+4)]/2=6 (as (b*h)/2=A)
x*x + 4*x -12 = 0
so, x = 2 units(as -6 is negative)
Answer:
Step-by-step explanation:
Given: A bag contains 4 sour-apple candies and 3 watermelon candies.
Total candies = 4+3 = 7
If replacement of candy is done, then the probability of getting sour apple will be the same and independent each time .
Probability of selecting sour apple candy=
Now , the probability that both pieces of candy chosen will be sour -apple =
hence, required probability =
