A system of equations for this would be

19x + 11y = 273

and

12x + 17y = 283.

X is the amount of minutes to solve one long division problem and y is the amount of minutes to solve a graphing problem.

How To Solve This System of Equations.

Multiply both by 17 and 11 respectively for them to have the greatest common factor for y. So now both equations are:

323x + 187y= 4641

132x + 187y= 3113.

Subtract both equations and you have left:

191x = 1528.

Divide both sides by 191 and you find x.

X = 8.

Answer

It takes Sally 8 minutes to do one Long Division Problem.


Hope this helped. ;)

The mold for a cone has diameter of 4 inches and is 6 inches tall what is the volume of the cone mold to the nearest tenth
Nesterboy [21]
The formula for the volume of a cone is
v = ( 1 / 3) h pi r^2
where h is the height of the cone
pi is 3.1416
r is the radius of the cone

since diameter is given
D = 2r
r = D/2 = 4/2 = 2 in

substitute the given
V = (1/3) (6) (3.1416) (2^2)
V = 25.1 cubic in

Solve and state any extraneous solutions
Mice21 [21]

\frac{3x}{x - 1}  + 2 =  \frac{3}{x - 1}

\frac{3x}{x - 1} +  \frac{2(x - 1) }{ x - 1}   =  \frac{3}{x - 1}

\frac{3x}{x - 1}  +  \frac{2x - 2}{ x - 1}  =  \frac{3}{x - 1}

\frac{3x + 2x - 2}{ x - 1}  =  \frac{3}{x - 1}

3x + 2x - 2 = 3

5x - 2 = 3

5x = 3 + 2

5x = 5

x =  \frac{5}{5}

x = 1

Solve -5y+6=-9 pls help me with this
alexandr402 [8]

Answer:

-5y + 6 = -9

y = 3

Step-by-step explanation:

subtract 6 from both sides

-5y + 6 - 6 = -9 - 6

simplify

-5y = -15

divide both sides by -5

(-5y)/5 = (-15)/5

simplify

y = 3
