Answer:
- v = 8
- x = -12
Step-by-step explanation:
1. I like to work with positive numbers, so the first thing I'd do is multiply the equation by -1.
2v + 7 = 23
2v = 16 . . . . . subtract 7
v = 8 . . . . . . . divide by 2
<em>Check</em>
-2(8) -7 = -23 . . . . true
___
2. (x/4) -5 = -8
x/4 = -3 . . . . . . . add 5
x = -12 . . . . . . . . multiply by 4
<em>Check</em>
(-12/4) -5 = -8 . . . . true
Answer: width = 280 miles, length = 380 miles
<u>Step-by-step explanation:</u>
width: L - 100
length: L
Perimeter = 2(Length) + 2(width)
1320 = 2(L) + 2(L-100)
1320 = 2L + 2L - 200
1320 = 4L - 200
1520 = 4L
380 = L
width: L - 100 ---> 380 - 100 = 280
length: L ---> 380
Answer:
equation of line:
y = mx + b....equation(1)
slope = m = -1/4
y-intercept = b =?
put point(12,5) and slope (-1/4) in equation(1)
5 = (-1/4)(12) + b
5 = -12/4 +b
5 = -3 + b
5 + 3 = b
b = 8
putting values of b and m in equation(1)
y = (-1/4)x + 8

Answer:
400sq.ft
Step-by-step explanation:
Let Area of smaller rectangle be x
➝2:3=x:600
➝2/3=x/600
➝2×600=3x
➝3x=1200
➝x=1200/3
➝x=400sq.ft
Y = 1
This the answer just trust
