Answer:
1 439 800
Step-by-step explanation:
200 x 80 x 90 - 200
= 16 000 x 90 - 200
= 1 440 000 - 200
= 1 439 800
1. 5x= -80. x= -16
2. x - 73 = 129. x = 202
3. x/-8 = 22. x = -176
4. 2x + 8 = 8. 2x = 0. x = 0
5. 3x - 7 = 40. 3x = 47. x = 47/3
The two equations are: 3x + 2y = 36.50 (I)2x + 5y = 50 (II)Eliminating x from the two equations by subtraction:first we multiply equation I by 2 and equation II by 36x + 4y = 736x + 15y = 150Subtracting the two,-11y = -77y = 7He earns $7 at the coffee cartSubstituting y into equation I,3x + 14 = 36.5x = $7.50Therefore, he earns a greater wage of $7.50 at the library, the answer is C
P = The kitchen is clean → TRUE
Q = The bedroom is clean → FALSE
1) If P is true, then Q is true. → False statement
2) Statement Q is true if and only if P is true. → False statement
3) Both p and q are true. → False statement
4) Statement P or Q is true. → True statement ⇒ Statement P is true.
The answer is: The statement "Statement P or Q is true" is true.
There you go! I really hope this helped, if there's anything just let me know! :)
