Here are 3 equivalent expressions that would represent the total number of pencils and pens in Karen's backpack.
1. 4p + 6
2. p+ p + p + p + 6
3. 6 + 4(p)
Each of these has four groups of p +6 represented.
ADDING THE 2 EQUATIONS TO ELIMINATE Y WE HAVE
-2.98x = -8.94
x = 3
Plug x=3 into first equation:-
-0.18(3) + y = -6.54
y = -6.54 +0.54 = -6
answer x= 3 and y= -6.
Answer:
The correct answer should be 48.
Step-by-step explanation:
To figure this out, simply divide 408 by 17 first to get 24. Since we are doing half of b, we need to do the inverse and multiply 24 by 2 to get b. 24 x 2 is 48. The equation in its form would now be 408=1/2(48)(17).
1/2 x 48 = 24
24 x 17 = 408.
So therefore, 48 is the correct answer.
