After 14 years, I shall be three times as old as I was 4 years ago. What is my present age?
Answer:
Present age = 13 years
Step-by-step explanation:
Let the present age be x years.
14 years after age = (x + 14) years
4 years ago age = (x - 4)
According to the given information:
14 years after age = 3 times 4 years ago age
x + 14 = 3(x - 4)
x + 14 = 3x - 12
14 + 12 = 3x - x
26 = 2x
x = 26/2
x = 13 years
Thus, the present age is 13 years

Bryans gocket team is purchasing jersys. The company charges $250 for the onetime set-up fee and $23 for each printed jersey which expression repressents the total cost of x number for the team
Given:
The company charges $250 for the onetime set-up fee and $23 for each printed jersey.
To find:
The expression that represents the total cost of x number for the team.
Solution:
We have,
Fixed charges = $250
Additional charges = $23 per printed jersey
Let x be the number of printed jersey. Then,
Additional charges = $23x
Total chargers = Fixed charges + Additional charges
= $(250 + 23x)
Therefore, the expression for the total charges is $(250 + 23x).

i need to find the 9th term of this sequence
9514 1404 393
Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.
During a theater matinee show, the power went out. The theater manager refunded the
ticket price to everyone attending. Let n represent the number of people attending the
show. Let r represent the total amount of money refunded. Wite an equation to represent
the amount of money refunded.
Ticket Price Board
Adults
$13.00
Children & Seniors
$11.00
Matinees: All Ages
$9.00
Answer:
r = 9n
Step-by-step explanation:
Ticket price of each tickets for the matinee show = $9 for all ages
If the number of persons who attended the matinee show = n
And the total amount refunded = r
Then the expression representing total amount refunded 'n' in terms of 'r' will be,
Total amount refunded = Price of ticket × Number of tickets
r = 9n

Step-by-step explanation:
Kathy distributes jelly beans among her friends.
Number of jelly beans received by Kelly after distribution of Jellies by Kathy = 33
Also, Alia gets 42 fewer jelly beans than Kelly
Now, we need to find the number of jelly beans received by Alia
So, Number of jelly beans received by Alia = No. of jelly beans received by Kelly - 33
⇒ Number of jelly beans received by Alia = 42 - 33
Therefore, The correct answer is D. 33 - 42

A TV has a listed price of $ 796-99 before tax. If the sales tax rate is 6.75% find the total cost of the TV with sales tax included
Round your answer to the nearest cent, as necessary
Answer:
$850.79
Step-by-step explanation:
Assuming "$ 796-99" meant $796.99
796.99 increase 6.75% =
796.99 × (1 + 6.75%) = 796.99 × (1 + 0.0675) = 850.786825
Please Help 1 24 + r ; r = 9 2 2a + 3 ; a = 10 3 Bc + 12.3 ; b = 9, c = 4 4 p ÷ q ; p = 24, q = 8 5 4c - 7.8 ; c = 4 6 c - a ; a = 3, c = 17 7 a ÷ 2c ; a = 20, c = 2 8 3x - 14 ; x = 5 9 1.5 + y² ; y = 6 10 t/5 + 6 ; t = 45
Answer:
See solution below
Step-by-step explanation:
Given the following expression
1) 24+r
If r = 9
24 + r = 24+9
= 33
2) 2a+3
If a = 10
Substitute
2(10)+3
= 20+3
= 23
3) BC+12.3
b = 9
c = 4
Substitute
= 9(4)+12.3
= 36+12.3
= 48.3
4) p÷q
Given p = 24 and q = 8
p÷q = 24÷8
p÷q = 3
5) 4c-7.8
If c = 4
Substitute
= 4(4)-7.8
= 16-7.8
= 8.2
6) c-a
a = 3
c = 17
Substitute
= 17-3
= 14
Hence c-a = 14
7) a ÷ 2c ; a = 20, c = 2
Substitute
a÷2c
= a/2c
= 20/2(2)
= 20/4
= 5
8) 3x-14
If x = 5
Substitute
= 3(5)-14
= 15-14
= 1
9) 1.5 + y² ; y = 6
Substitute
= 1.5+6²
= 1.5+36
= 37.5
10) t/5 + 6 ; t = 45
substitute the value of t given into the expression
= 45/5 + 6
= 9 + 6
= 15

A cookie delivery company charges $0.90 per cookie plus a $3 delivery fee. If an
order costs $11.10, how many cookies were ordered?
Answer:
9 cookies
Step-by-step explanation:
The equation is 11.1 = 0.9x + 3. First, we need to isolate the variable so we subtract 3 from both sides. 8.1 = 0.9x. Next we divide both sides by 0.9 which gives us 9 = x or x = 9.

i need help with geometry!
Step-by-step explanation:
If m is parallel to n and one of its angle is 25
Therefore, the vertically opposite angle to angle of 25 is also equal to 25
Now, we have to find x
Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)
Therefore, x =155
Solve for x 8.2/x =12/6.4
