You need to get the r by itself on one side, with the constants (numbers without the r) on the other side.

$6r+7=13+7r\\6r-7r+7=13+7r-7r\\-r+7=13\\-r+7-7=13-7\\-r=6\\-r/-1=6/-1\\r=-6$

Yao Xin puts \dfrac{3}{10} 10 3 ? start fraction, 3, divided by, 10, end fraction liters of potting soil in each pot for plantin

slega [8]

Answer:

Step-by-step explanation:

Yao Xin puts $\frac{3}{10}$ liters of potting soil in each pot.

Suppose, the number of pots Yao Xin can fill is $x$

So, <u>the total amount of potting soil</u> in $x$ number of pots will be: $\frac{3}{10}x$ liters.

Given that, she has $5\frac{2}{3} or \frac{17}{3}$ liters of potting soil. So, the equation will be........

$\frac{3}{10}x= \frac{17}{3} \\ \\ x=\frac{17}{3}* \frac{10}{3}= \frac{170}{9}=18\frac{8}{9}$

So, she can fill pots.

Need help please! Will give it to the brainliest. Which expression models the bacterium's volume? Picture is below.

Tomtit [17]

The expression C. $\pi (1)^{2} (0.5)$ cubic $\mu \mathrm{m}$ represents the bacterium's volume.

Step-by-step explanation:

Step 1:

The E. Coli bacterium is in the shape of a cylinder.

The volume of a cylinder is given by multiplying π with the square of the radius (r²) and the height of the cylinder.

The volume of a cylinder, $V=\pi r^{2} h.$

In the given diagram, E. Coli has a radius of 1 $\mu \mathrm{m}$ and a height of 0.5 $\mu \mathrm{m}$ .

Step 2:

By substituting the values in the equation, we get

The volume of the E. Coli bacterium $= \pi (1)^{2} (0.5)$ cubic $\mu \mathrm{m}$ .

This is option C.
