Answer:3
Step-by-step explanation:if it is 3 cubes tall that means it will be 3 cubes
16+16=32 then just add four its easy to me
Answer: x= -4 , y= 1
Step-by-step explanation:
X= weight of TV
y= weight of CD
3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:
3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.
Now plug y= 3.5 back into any equation to get x:
3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5
It is opposite of what the equation is saying. Like if you had to add you would subtract or if you multiply you would divide.
