No of People who can speak French is 
No of People who can speak Spanish is 
No of People who can speak both English and French 
No of People who can speak both English and Spanish 
No of People who can speak both French and Spanish 
No of people who can speak all languages is 
no of People who can Speak at least one Language is


Probability that Randomly selected can speak at least 1 of these languages
All four sides of the original square have length s.
Adding 3 to s results in s+3, the length of the resulting rectangle.
Subtracting 3 from s results in s-3, the width of the rectangle.
The area of the rectangle is (s+3)(s-3) = s^2 - 9 = 27,
and therefore s^2 = 36, and s = 6 square units.
The 2 equations are
-2x + y = -17 ---1)
3x + y = 23 ---2)
we need to have the same coefficient for one of the variables.
Already y variable has the coefficient of 1 for both equations so we can use the equations as it is.
2) - 1) subtract 1) from 2)
3x-(-2x) + y -y = 23-(-17)
5x = 40
x = 8
substituting x = 8 in the 2nd equation
3*8 + y = 23
24 + y = 23
y = -1
solution - (8,-1)
Answer:
B
Step-by-step explanation:
If you look at A and you subtract 3x by 4x you get x and you subtract 3 from -7 and you get -10. But if you look at B you do the stuff in the parentheses first and you get 4x+12x+28=16x+28 and they're the same so it's B.
Given that S<span>hanley would like to give $5 gift cards and $4 teddy bears as party favors and that Shanley has $128 to spend on party favors.
The inequality to find the number of </span><span>gift cards x and teddy bears y Shanley could purchase</span> is given by

One solution to the inequality is that Shanley can buy 12 gift cards and 15 teddy bears.
