Answer:
24c
Step-by-step explanation:
Difference= big value - small value
When minus is put side by side, it becomes a plus.
17c-(-7c)=17c+7c=24c
Answer:
56 total
Step-by-step explanation:
Let the number of girls = x
Let the number of boys = 3x
x 1
=== = ==========
x + 28 3
Cross multiply
3x = x + 28 Subtract x from both sides
3x - x = 28 Combine
2x = 28 Divide by 2
x = 28/2
x = 14
Girls = 14
Boys = 14 + 28 = 42
Is the ratio 3 to 1?
42/14 = 3/1 Yes it does
Total number
14 + 42 = 56
Q + s = q + 1, we know because you can substitute s for 1 according to the number line.
Answer:
El perímetro del triángulo rectángulo es aproximadamente 29.627.
Step-by-step explanation:
Las coordendas de los vértices del triángulo rectángulo son 
, 
y 
. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:
![AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}](https://tex.z-dn.net/?f=AB%20%3D%20%5Csqrt%7B%28-8-1%29%5E%7B2%7D%2B%5B4-%28-2%29%5D%5E%7B2%7D%7D)
![BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}](https://tex.z-dn.net/?f=BC%20%3D%20%5Csqrt%7B%5B5-%28-8%29%5D%5E%7B2%7D%2B%282-4%29%5E%7B2%7D%7D)
![AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}](https://tex.z-dn.net/?f=AC%20%3D%5Csqrt%7B%285-1%29%5E%7B2%7D%2B%5B2-%28-2%29%5D%5E%7B2%7D%7D)
El perímetro del triángulo (
) es la suma de todos estos segmentos:
El perímetro del triángulo rectángulo es aproximadamente 29.627.
