Answer: You bought 7 books and you also bought 4 magazines
Explanation:
x = # of books purchased
y = # of magazines purchased
System of equations:
8x + 5y = 76
x + y = 11
Let’s use elimination in this case, but substitution can also work.
8x + 5y = 76
Multiply the (x + y = 11) by -8
We get:
8x + 5y = 76
-8x - 8y = -88
The xs cancel.
Add like terms.
-3y = -12
Divide by -3 on both sides
y = 4
Now plug in 4 into the (x + y = 11) equation to get x.
x + (4) = 11
Subtract 4 on both sides
x = 7

Given:
Rule of transformation is 
.
Point = (-5,6)
To find:
The missing values in the given steps of transformation.
Solution:
Step 1: A: (-5, 6).
Step 2: Substitute x and y into 
Step 3: Do the math:
Point A' is at (-1 ,4 ).
Therefore, the coordinates of the point (-5,6) after the transformation are (-1,4).
If there is a 22.4% chance that a soccer player will make 4 shots in a row, then the probability that he/she WON'T make 4 shots in a row is...
100 -22.4 = 77.6%
So the number of simulations that he/she will miss at least one shot in 2500 simulations would be...
2500 x 77.6% =
2500 x .776 = 1940
Answer:
Step-by-step explanation:
Multiplying both sides by 100.
