If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm
(3 × 14) + 38
42 + 38 = 80 cm
So the perimeter would be 80 cm.
I hope this helps!
The answer would be (4,3)
Answer: The mean is 3.5. The range is 7. The median is 3, and finally the mode is 4.
Answer:
y = (-1/2)x
Step-by-step explanation:
As we go from (-4, 2) to (6, -3), x (the "run") increases by 10 and y (the "rise") decreases by 5. Thus, the slope of the line connecting these two points is m = rise / run = m = -5/10, or m = -1/2.
We adapt the slope-intercept form as follows: y = mx + b becomes
2 = (-1/2)(-4) + b, or
2 = 2 + b. Therefore, b must be 0. The desired eequation is y = (-1/2)x.
Answer:
Work backwards to solve this problem.
If he ends with 32 cookies, then subtract 12. That gives 20 cookies. 20*2 is 40, so now he has 40 cookies.
