For the following system, if you isolated x in the first equation to use the substitution method, what expression would you subs

alekssr [168]

Answer:

$x=2y+6$

Step-by-step explanation:

So we have the system:

$-x+2y=-6\\3x+y=8$

If we isolate the x-variable in the first equation:

$-x+2y=-6$

Subtract 2y from both sides:

$-x=-6-2y$

Divide both sides by -1:

$x=2y+6$

Therefore, we would substitute the above into the second equation:

$3x+y=8\\3(2y+6)+y=8$

The answer is 2y+6

Further notes:

To solve for the system, distribute:

$6y+18+y=8$

Simplify:

$7y+18=8$

Subtract:

$7y=-10$

Divide:

$y=-10/7\approx-1.4286$

Now, substitute this value back into the isolated equation:

$x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429$

The area of the curved surface of a cylindrical can is 162 π square centimeters and it’s height is 9 centimeters. What is the di

asambeis [7]

Answer:

Diameter of the can = 18 Cm

Step-by-step explanation:

Given:

Curved surface of cylindrical can = 162 $\pi$

Height of cylindrical can = 9 Cm

Find:

Diameter of the can = ?

Computation:

Curved surface of cylindrical can = 2 $\pi$ rh

$162\pi = 2\pi rh\\\\\frac{162\pi }{2\pi }= r\times 9\\\\81 = r\times 9\\\\\frac{81}{9}=r$

$r=9 Cm$

Diameter of the can = 2×r

Diameter of the can = 2×9 Cm

Diameter of the can = 18 Cm
