Answer:

23: y = -0.4

24: b = -1.8

25: m = 1/2

26: g = 1/4

27: s = 3/2

28: w = -12/5

29: z = 5/4

30: a = -9/5

Step-by-step explanation:

23:

  • 3y + 5.2 = -5y + 2
  • 3y+5.2+5y=-5y+2+5y
  • 8y + 5.2 = 2
  • 8y+5.2-5.2=2-5.2
  • 8y = -3.2
  • \frac{8y}{8} = \frac{-3.2}{8}
  • y = -0.4

24:

  • 10b-2=7b-7.4
  • 10b-2-7b=7b-7.4-7b
  • 3b - 2 = -7.4
  • 3b -2 + 2 = -7.4 + 2
  • 3b = -5.4
  • \frac{3b}{3} = \frac{-5.4}{3}
  • b = -1.8

25:

  • 2m - 2 = 6m - 4
  • 2m-2-6m=6m-4-6m
  • -4m-2=-4
  • -4m-2+2=-4+2
  • -4m = -2
  • \frac{-4m}{-4} = \frac{-2}{-4}
  • m = \frac{1}{2}

26:  

  • 3g+5=7g+4
  • 3g+5-7g=7g+4-7g
  • -4g+5=4
  • -4g + 5 - 5 = 4-5
  • -4g = -1
  • \frac{-4g}{-4} = \frac{-1}{-4}
  • g = \frac{1}{4}

27:

  • 4s-1=-2s+8
  • 4s-1+2s=-2s+8+2s
  • 6s - 1 = 8
  • 6s - 1 + 1 = 8+1
  • 6s = 9
  • \frac{6s}{6} = \frac{9}{6}
  • s = \frac{3}{2}

28:

  • 9w+3=4w-9
  • 9w+3-4w=4w-9-4w
  • 5w + 3=-9
  • 5w + 3 - 3 = -9-3
  • 5w = -12
  • \frac{5w}{5} = \frac{-12}{5}
  • w = \frac{-12}{5}

29:

  • 6z-7=2z-2
  • 6z-7-2z=2z-2-2z
  • 4z -7 = -2
  • 4z-7+7=-2+7
  • 4z = 5
  • \frac{4z}{4} = \frac{5}{4}
  • z = \frac{5}{4}

30:

  • -a+3=4a+12
  • -a+3-4a=4a+12-4a
  • -5a+3=12
  • -5a + 3 - 3 = 12-3
  • -5a = 9
  • \frac{-5a}{-5} = \frac{9}{-5}
  • a = -\frac{9}{5}

Y is inversely proportional to a^3
Ludmilka [50]

Answer:

y = 0.64/x^3

Step-by-step explanation:

If y is inversely proportional to a^3, we can write the equation:

y * a^3 = k

Using a = 2 and y = 10, we have:

10 * 2^3 = k

k = 80

If a is directly proportional to x, we can write the equation:

a = c * x

Using x = 4 and a = 20, we have:

20 = c * 4

c = 5

Now, using the value of a = 5*x in the equation y * a^3 = 80, we have:

y * (5x)^3 = 80

y * 125x3 = 80

y = 80/(125x3) = 0.64/x^3
