Answer:
30 cm
Step-by-step explanation:
To find the perimeter of the rectangle, you first need to find the width and length of the rectangle:
54/9 = 6
L = 9
W = 6
The perimeter is 2lw:
The answer is 30 cm
y + 9 = 9
Subtract 9 to both sides to isolate the 9 on the y. Whatever you do on one side you have to do it to the other side, your answer should be
y + 9 = 9
- 9 - 9
y = 0
Answer:
5x= -15 I think
Step-by-step explanation:
You would have to solve the -6x+11=29 to find the value of x. To do so you would subtract the 11 from both sides leaving you with -6x=18. Then you divide that by -6 to find x. So x=-3. To find what 5x equals you would just plug in -3 as x and multiply 5(-3). Leaving you with -15.
Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B
