Answer:

x = 2.6

7x+1

Step-by-step explanation:

<u>If 4.75x = 12.35, what is the value of x?</u>

You need to solve this equation. To do so, we need to isolate the x variable by itself. So, we will divide both sides by 4.75 to get our answer for x.

$4.75x = 12.35\\\frac{4.75x}{4.75} = \frac{12.35}{4.75}\\x= 2.6$

x = 2.6

<u>What is 3x+2+4x-1 after combining like terms?</u>

To combine like terms, it means to simplify/merge them together. We know what 1 +2 is? Why write 1 +2, when we can just say 3? That's basically what the question is asking.

Anyway,

$3x+2+4x-1\\$

Merge the x's (DON'T SEPERATE THE X IF ITS BESIDE A NUMBER!!! IT WILL BE MULTIPLIED BY X)

$7x+2-1$

Now simply 2-1.

$7x+1$

Simplified version: 7x+1

The spherical balloon is inflated at the rate of 10 m³/sec. Find the rate at which the surface area is increasing when the radiu

rjkz [21]

The balloon has a volume $V$ dependent on its radius $r$ :

$V(r)=\dfrac43\pi r^3$

Differentiating with respect to time $t$ gives

$\dfrac{\mathrm dV}{\mathrm dt}=4\pi r^2\dfrac{\mathrm dr}{\mathrm dt}$

If the volume is increasing at a rate of 10 cubic m/s, then at the moment the radius is 3 m, it is increasing at a rate of

$10\dfrac{\mathrm m^3}{\mathrm s}=4\pi (3\,\mathrm m)^2\dfrac{\mathrm dr}{\mathrm dt}\implies\dfrac{\mathrm dr}{\mathrm dt}=\dfrac5{18\pi}\dfrac{\rm m}{\rm s}$
