Answer:

a = -3

Step-by-step explanation:

3a−6a+2=8a+20−5a ( original equation)

Step 1: Simplify both sides of the equation.

3a−6a+2=8a+20−5a

3a+−6a+2=8a+20+−5a

(3a+−6a)+(2)=(8a+−5a)+(20)(Combine Like Terms)

−3a+2=3a+20

−3a+2=3a+20

Step 2: Subtract 3a from both sides.

−3a+2−3a=3a+20−3a

−6a+2=20

Step 3: Subtract 2 from both sides.

−6a+2−2=20−2

−6a=18

Step 4: Divide both sides by -6.

−6a/−6 = 18/-6

a=−3

6. A surveyor walks the perimeter of a piece of government land. He notes that the area of the land
Vlada [557]

Answer:

A) l = w + 900

B) l * w = 4,000,000

B) l = 4,000,000 / w putting this into A)

A) 4,000,000 / w = w + 900

A) 4,000,000 = w^2 +900 w

A) w^2 +900 w - 4,000,000

Solving by quadratic formula

width = 1,600 length = 2,500

Double-Check

1,600 * 2,500 = 4,000,000

Length = width + 900

2,500 = 1,600 + 900

Answer is okay

Solve for a r=x(a+b)<br><br><br> Solve for x x/2=-7
Anastaziya [24]

Answer:

a = (r/x) -b

x = -14

Step-by-step explanation:

r=x(a+b)

Divide each side by x

r/x = a+b

Subtract b

r/x  -b = a

x/2=-7

Multiply each side by 2

x/2*2 = -7*2

x = -14
