Answer:
2,784 lbs
Step-by-step explanation:
2900/100=29 (that is 1% of the 2900)
29*4=116 (that is 4% of 2900; how much weight they lost)
2900-116=2784 (current weight)
Erm..Idk, sorry I tried to help but couldn't find it.
So, if the legs are a and b and the hypothuse is c then
a²+b²=c²
the distance bewteen the points is the hyptohuse
the legs are the distances between th x and y values
so
(7,11) and (-1,5)
distances between the x values are 1 leg
that is from 7 and -1, a distance of 8 units
distances betweeen the y values are the other leg
that is from 11 to 5
that is 6 units
a²+b²=c²
8²+6²=c²
64+36=c²
100=c²
sqrt both sides
10=c
the distance between them is 10 units
Hello,
The 3th angle of the triangle is the supplement of 3x-8:
180-(3x-8)=180-3x+8=188-3x
The sum of all angles of the triangle is 180
180=2x+21+188-3x
==>180=-x+21+188
==>x=21+188-180
==>x=21+8
==>x=29
1 + 3n + 7n = 7(n + 4) + 6(3n + 3)
1 + 3n + 7n = 7n + 28 + 18n + 18
10n + 1 = 25n +46
25n - 10n = 1 - 46
15n = -45
n = -45/15
n =-3
