Answer:
<em>He bought 6 hotdogs and 2 drinks</em>
Step-by-step explanation:
<u>System of Equations</u>
Kevin and his children went into a restaurant and bought $31.50 worth of hotdogs and drinks. Each hotdog costs $4.50 and each drink costs $2.25.
To solve the system of equations, we'll call the variables:
x = number of hotdogs
y = number of drinks
The first condition yields the equation:
4.50x + 2.25y = 31.50 [1]
It's also known he bought 3 times as many hotdogs as drinks, thus:
x = 3y [2}
Substituting [2] in [1]:
4.50(3y) + 2.25y = 31.50
Operating:
13.5y + 2.25y = 31.50
15.75y = 31.50
y = 31.50/15.75
y = 2
And
x = 3*2 = 6
He bought 6 hotdogs and 2 drinks
Answer:
99.96%
Step-by-step explanation:
Given the information:
=> the are 25 people in total
Hence, the total possible outcomes of all the members in the 4 committee:
They want us to find the probability that the committee will consist of at least one student, which means that
=(Total possible outcome - committee with no student) / Total possible outcomes
So we need to find the possible outcomes of committee with no student:
= 
=> the probability that the committee will consist of at least one student.
= (12650 - 5) / 12650
= 0.9996
= 99.96%
Hope it will find you well.
Answer:
1. 2,3; -2, 3
2. Both points share common values, but their absolute values for the x-value vary.
3. 2,3; 2, -3
4. Both points share common values, but their absolute values for the y-value vary.
Step-by-step explanation:
For 1, the answer is thus:
-On the graph, the original point is 2, 3.
-A reflection over the y-axis changes the x-value, so it would be -2,3.
Similar for the next chart:
-The initial point is 2,3.
-A reflection over the x-axis changes the y-value, so the reflected point would be 2, -3.
The explanation is:
Both points have similar values except with differences in the absolute value.
Hope this helps you.
Jax gets 4 packs per month...each pack contains 4 cards...so he gets 16 cards per month.
Sofia gets 3 packs per month..each pack contains 4 cards...so she gets 12 cards per month..
56 + 16m = 68 + 12m
16m - 12m = 68 - 56
4m = 12
m = 12/4
m = 3.....they will have the same number of cards in 3 months
Jax : 56 + 16(3) = 104 cards
Sofia : 68 + 12(3) = 104 cards
and they will both have 104 cards
