Answer:

14y=4x

Step-by-step explanation:

8y+4x+6y=

ok so first you get the groups like group the y's and the x's but their is no pair for the x so you leave it alone but you add 8y+6y=14y then you put down 14y=4x

NemiM [27]

Answer:

B. 314 cm³

Step-by-step explanation:

We are given that,

Height of the cone = 12 cm

Radius of the cone = 5 cm

<em>Since, we need to fill the cone with the cement. So, we will find the volume of the cone.</em>

So, Volume of the cone = $\frac{1}{3}\pi r^{2}h$

i.e. Volume of the cone = $\frac{1}{3}\pi 5^{2}\times 12$

i.e. Volume of the cone = $\frac{1}{3}\times 3.14 \times 25\times 12$

i.e. Volume of the cone = $\frac{942}{3}$

i.e. Volume of the cone = 314 cm³

Hence, the amount of cement they can put in each cone is 314 cm³.

Re-write the following expression using ADDITION ONLY:<br> 12- 3+16 - 37 - (-20)

poizon [28]

12- 3+16 - 37 - (-20)
=9+16-37-(-20)
=25-37-(-20)
=-12-(-20)
=8
(therefore ur answer would be 8)

Consider functions f and g

alexdok [17]

Answer:

Step-by-step explanation:

$f(x) = \dfrac{x - 16}{x^2 + 6x - 40}$

$g(x) = \dfrac{1}{x + 10}$

$f(x) + g(x) = \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{1}{x + 10}$

$f(x) + g(x) = \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{(x - 4)}{(x + 10)(x - 4)}$

$f(x) + g(x) = \dfrac{x - 16 + x - 4}{x^2 + 6x - 40}$

$f(x) + g(x) = \dfrac{2x - 20}{x^2 + 6x - 40}$

Answer:

$PQ=22\\\\QR=7\\\\PR=29$

Step-by-step explanation:

To find the value of y, you can create an equation where two parts of the line are equal to the whole line:

$PQ+QR=PR$

Substitute given values:

$(8y+6)+(y+5)=(19y-9)$

Solve for y. Simplify parentheses:

$8y+6+y+5=19y-9$

Combine like terms to simplify the equation:

$8y+y+6+5=19y-9\\\\9y+11=19y-9$

Get the variable on one side of the equation and the constants on the other. Add 9 to both sides:

$9y+11+9=19y-9+9\\\\9y+20=19y$

Subtract 9y from both sides:

$9y-9y+20=19y-9y\\\\20=10y$

Isolate the variable. Divide both sides by 10:

$\frac{20}{10} =\frac{10y}{10} \\\\y=2$

The value of y is 2. Insert this value into each line segment value and solve:

$PQ=8(2)+6\\\\PQ=16+6\\\\PQ=22$

$QR=(2)+5\\\\QR=7$

$PR=19(2)-9\\\\PR=38-9\\\\PR=29$

:Done

You can check by using:

$PQ+QR=PR\\\\22+7=29$

This statement is true, so the values are correct.
