Answer:
Hope this helps. x=12 and y= -10
Answer:
I believe the final answer is x=3
Step-by-step explanation:
when trying to solve equations, always sort things out and prioritize things, that way it's easier to get to the final answer.
x+2x-5=4
3x-5=4 just move the -5 to the other side and make it a positive
3x=9
x+y=4
y=1
3+1=4
First, you would solve the parentheses.
72-(7+8)*4
72-(15)*4
Then, you would do multiplication.
72-60=
12
Hope this helps!
For this question you should know that 3.5 = 35/10 and 3/5 = 9/10 so you can see that 35/10 is not as same as 9/10 :)))
i hope this is helpful
have a nice day
Answer:
84
Step-by-step explanation:
To get from 4 to 12, you multiply with 3.
Everything is 3 times as big in the larger rectangle.
This includes the perimeter.
Example:
small rect 4x10, perimeter 4+4+10+10 = 28
large rect 12x30, perimeter 12+12+30+30 = 84
but also 28x3 = 84
