Answer:

R=51

Step-by-step explanation:

6x-9+7x=121

add like terms:6x+7x=13x

13x-9=121

to cancel out (-9) and to isolate x, add on both sides

13x=130

divide into both sides

x=10

<h3>to solve for angle R</h3>

substitute 10 for x

6(10)-9

R=51

The density of lead is 11.4g/cm^3 at 25 degrees C. Calculate the volume occupied by 25.0g of lead

ElenaW [278]

Answer:

2.193 cm³

Step-by-step explanation:

density is mass divided by volume:

$density = \frac{mass}{volume}$

you can manipulate the formula by multiplying with volume:

$density \times volume = mass$

then dividing by density:

$volume = \frac{mass}{density}$

in this case:

$volume = \frac{25g}{11.4 \frac{g}{cm} } = 2.193 { \: cm}^{3}$
