Answer:
One blueberry pie = $7
One pumpkin pie = $16
Step-by-step explanation:
Since there are two variables in this problem - the cost of blueberry pie and the cost of pumpkin pie, we can set up a system of equations to solve. Since Brandy sold 6 blueberry pies and 4 pumpkin pies for $106, our first equation is: 6b + 4p = 106.
Molly sold 6 blueberry and 3 pumpkin for $90, so the second equation is: 6b + 3p = $90.
We can use elimination to add the two equations together and eliminate one variable while we solve for the other:
6b + 4p = 106
6b + 3p = 90
In order to eliminate a variable, you can multiply the first equation by -1:
-1(6b + 4p = 106) = -6b - 4p = -106
Add<u> 6b + 3p = 90</u>
-p = -16, so p = 16
Now, solve for b: 6b + 3(16) = 106 or 6b + 48 = 90
Subtract 48 from both sides: 6b + 48 - 48 = 90-48
Divide by 6: 6b/6 = 42/6
Solve for b: b = 7
Answer: option B. 2/11
Explanation:
1)
number of positive outcomes
Probability = ------------------------------------------
number of possible outcomes
2) Number of positive outcomes:
The positive outcome is choosing a T, given that there are two Ts, the number of positive outcomes is 2.
3) Number of possible outcomes
There are 11 letters, so the number of total outcomes is 11.
4) Therefore,
2
probability = ------
11
The student would have to score 100% on their next test to brung their average up to 90. Here is why;
90+84+86=260
(260+?)/4=90
(260+100)/4=90
360/4=90
This is done to get the mean (or average) of a group of numbers by adding all the numbers and dividing by the amount of numbers you added together. Here it is divided by 4 because of the three tests he has taken and the test he will take.
Answer:The fourth option
decreases by 1 minute every 2 hours trained
Step-by-step explanation:
If y is how much it decreses its negative, and if the slope is -1/2 then they decrease by one for every 2 hours since the two represents x.
