2. Solve each given equation and show your work. Tell whether each equation has one solution, an infinite number of solutions, o
Ugo [173]
Alright,

(a) 2x+4(x-1)=2
2x+4x-4=2---- Distrubution of 4(x-1)
6x-4=2---- Combining like terms
6x=6---- Making -4 equal 0 by adding +4 to both sides
x=1---- Divide the coefficiant (6)

(b) 25-x=15-(3x+10)
25-x=15-3x-10----Distribute the -1
25-x=5-3x---- Combine like terms
25=5-2x---- Make -x equal 0 by adding +x to both sides
20=-2x---- Make 5 equal zero by subtracting 5 (or adding -5) to both sides
-10=x---- Divide by the coefficiant (-2)

(c) 4x= 2x+2x+5(x-x)
4x=2x+2x+5(0)---- Distribute. Alright this might look hard but realy it is 1x-1x so the answer is 0
4x=2x+2x---- 5 times 0 is 0
4x=4x---- Combine like terms
x=x ---- divide by the coefficiant

Alright! Hope this helps! ;)

Ray Of Light [21]

Answer:

  • field size: 1750 acres
  • developed area: 1400 acres

Step-by-step explanation:

If the developed area is 80% of the field, and the undeveloped area is 20%, then the developed area is 4 times the undeveloped area, so is ...

  developed area = 4 × 350 acres

  developed area = 1400 acres

Then the total area is ...

  total area = developed area + undeveloped area = (1400 +350) acres

  total area = 1750 acres
