Answer:

X = -5

Step-by-step explanation:

-6x + 18 = 7 - (4x + 9)

first we simplify the parentheses.

distribute the invisible number one created by the negative sign in front of the parentheses to get -6x + 18 = 7 - 4x - 9

then simplify further by subtracting 9 from the right side, leaving you with

-6x + 18 = -2 - 4x

next, add 2 to both sides to isolate the variable.

-6x + 20 = -4x

then, to isolate the variable further add 6x to both sides.

20 = -4x

divide both sides by -4 to isolate the variable

-5 = x

so, x = -5

anastassius [24]

Answer:

c = 100, a = 50, s = 20

Step-by-step explanation:

following information is missing from the question

6c + 7a + 2s = 990

3c + 3a + 4s = 430

2c + 4a + 4s = 480

If you solve the equation by putting in the values given in the option you will deduce that only option d matches LHS to the RHS

Lets see how,

6c + 7a + 2s = 990                

where, c = 100, a = 50, s = 20

6(100) + 7(50) + 2(20) = 990

600 + 750 + 40 = 990

990 = 990 hence true

2c + 4a + 4s = 480                     where, c = 100, a = 50, s = 20

2 (100) + 4 ( 50) + 4 (20)  = 480

200 + 250 + 80  =  480

See for the other option too with the same steps done above  to have a more clear understanding :)

Solve the formula for x.<br> S=2πzx+7πz2
Lubov Fominskaja [6]

Answer:

<u>Given:</u>

  • S = 2πzx + 7πz²

<u>Isolate x:</u>

  • 2πzx = S - 7πz²

<u>Divide both sides by 2πz:</u>

  • x = (S - 7πz²)/(2πz)
  • x = S/(2πz) - 3.5z
