1. –2v – 7 = –23 (1 point) 15 8 –8 –15 2. Start Fraction x over 4 End Fraction – 5 = –8 (1 point) –27 –12 –7 12
lara [203]

Answer:

  1. v = 8
  2. 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

The shape of Colorado is nearly a rectangle. The width is 100 miles less than the length. The perimeter is
lilavasa [31]

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

Slope: -1/4 point (12,5)
Jlenok [28]

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
