Answer:
cost of tacos=$2
cost of soda=$1
Step-by-step explanation:
x=price of tacos
y=price of soda
3x+y=7 --> y=7-3x
4x+2y=10 --> y=5-2x
5-2x=7-3x
x=2
y=5-2(2)=1
Answer:
3/26
Step-by-step explanation:
Probability of the first box to have the secret decoder ring is 18 out of 52:
Probability of the second box to have the ring is 17 out of 51, because one box with the ring already selected and not counted:
Probability that both of them have the secret decoder ring:
<u>So the answer is</u> 3/26
Answer:
13x + 14
Step-by-step explanation:
5x + 6 + 3x = 8x + 6.
8x + 6 + x + 1 + x + 1 + 2= 10x + 10
10x + 10 + (2²)(i think) = 10x + 14
10x + 14 + 3x = 13x + 14
final answer
Answer:
To spend at most $93, they need to rent the room less than or equal 13 hours.
Step-by-step explanation:
<u><em>The complete question is</em></u>
To rent a certain meeting room, a college charges a reservation fee of $15 and an additional fee of $6 per hour. The chemistry club wants to spend at most $93 on renting a room. What are the possible numbers of hours the chemistry club could rent the meeting room? Use t for the number of hours. Write your answer as an inequality solved for t,
Let
t ----> the number of hours
we know that
I this problem the word "at most" means "less than or equal to"
The number of hours rented multiplied by the cost per hour, plus the reservation fee, must be less than or equal to $93
so
The inequality that represent this situation is

solve for t
subtract 15 both sides


Divide by 6 both sides

therefore
To spend at most $93, they need to rent the room less than or equal 13 hours.
Answer:15 times
Step-by-step explanation:
For the 3 batches it is 3 x 5/4 (5/4 is how much each batch costs)=15/4
And you must divide 15/4 by 1/4 or multiply it by 4 crossing out the denominator giving you your answer 15
