The expression 12a+7s is the cost, in dollars, for a adults s students to enter the local marching band competition. Find the total cost for 4 adults and 30 students.Before you delete this I did try on my own and this has been confusing me

Answers

Answer 1

Answer: If 12A is equal to one adult, then this means that one adult will cost $12 to enter.
The same applies for the students, if 7s is equal to one student, then the cost of one student is $7.
As you've got four adults, then you need to find the cost of 4, and you do this by multiply 4 by 12.
4x12=$48
As you've got 30 students, you then need to multiply 30 by 7.
30x7=$210.
To find the total cost, you've then got to add $48 and $210 together.
$48+$210= $258.

Therefore, the total cost for 4 adults and 30 students is $258
Hope this helps :)

Answer 2

Answer: a=$4, s=$30

=12($4)+7($30)
=$48+$210
=$258

if 3 is added to a number and the sum is tripled, the result is 19 more than the number. find the number

Answers

Answer:

The number is 5

Step-by-step explanation:

if 3 is added to a number and the sum is tripled, the result is 19 more than the number

(n+3) *3 = n+19

Distribute the 3

3n +9 = n+19

Subtract n from each side

3n-n +9 = n-n+19

2n +9 = 19

Subtract 9 from each side

2n+9-9 = 19-9

2n =10

Divide by 2

2n/2 =10/2

n=5

The number is 5

Answer:

(x + 3)·3 = x + 19 --> x = 5
