1 answer:
First, you need to isolate the variable.
Subtract four from both sides of the equation. x/2 = -3
Multiply both sides by two. x = -6
Substitute to check your answer.
4 + (-6)/2 = 1
4 + -3 = 1
1 = 1
Our solution is correct

Answer:
That point P(x,y)
x = (-2+10)/2 = 4
y = (3+3)/2 = 3
=> P (4,3)
2876 Rounds To 3000
513 Rounds To 500
18 Rounds To 20
Then multiply:
3000x500x20= 30,000,000

Answer:1. 0.35. 0.35
Step-by-step explanation:
I did the question on edgenuity
P=2l+2w
W=7+3l
So substitute into the original equation
P=2l + 2(7+3l)
78=2l +14 + 6l
-14 -14
—————-
64=8l
8=length
W=7+3l
= 7+3(8)
=7+24
=31
Check your work
Perimeter=8+8+31+31
=78
Hope this helps
