Answer:
x/2+1000
Step-by-step explanation:
the mother received $4000 and the son received $3000, $4000/2 equals $2000, $2000 plus $1000 equals $3000
Answer: 5.1 x 10to the fourth exponent.
If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)
Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .
[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []
27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m
<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>
-4 , -8 because -4 is on the x axis and -8 is on the y axis
Answer:
10
Step-by-step explanation:
height = 2(Base) + 4
h = 2b + 4
Area of Triangle
A= bh/2
15 = b (2b) +4) / 2 multiply both sides by 2 and distribute the b
30 = 2
+ 4b Divide everything by 2
15 = + 2b Subtract 15 from both sides
+ 2b -15 = 0 Look a quadratic. Factor or use quadratic formula
b = 3 or b = -5 Measurements of length can't be negative. So its 3
h = 2(3) + 4 Substitute 3 in to find height
h = 10
