Answer:

Step-by-step explanation:

1. here you go mate

step 1

6x - 12 < 6  equation

step 2

6x - 12 < 6  simplify

6x-12+12<6+12

step 3

6x<18  Divide both sides

\frac{6x}{6}

answer

x<3

2. Here you go mate

step 1

2(3x-8) >8  equation

step 2

2(3x-8) >8  simplify

6x-16+16>8+16

step 3

6x>24  divide both sides

\frac{6x}{6} >\frac{24}{6}

answer

The formula for the volume of w sphere is v=4\3 r3 what is the formula solved for r?
Lyrx [107]
V of w sphere = \frac{4}{3}\pir³
Multiply by 3 on either sides to get rid of the fraction.
V * 3 =  \frac{4}{3} *3 \pi r^3
3V = 4\pir³
Now divide either sides by 4\pi to isolate r³
\frac{3V}{4 \pi } =  \frac{4 \pi }{4 \pi }r³
4\pi and 4\pi cancels out
\frac{3V}{4 \pi } = r³
Take the cube root to isolate r.
\sqrt[3]{ \frac{3V}{4 \pi } } =  \sqrt[3]{r^3}
the cube root cancels the cube

\sqrt[3]{ \frac{3V}{4 \pi } } = r

The sum of 3 times a number and 7 is 25
hammer [34]

Mathematically written:

3 * x + 7 = 25

3x + 7 = 25

3x = 25 - 7

3x = 18

x = 18 / 3

x = 6



Proof:

3 * 6 + 7 = 25

18 + 7 = 25

25 = 25 → both sides of the equation are equal, our answer is correct



Notes:

A number - Is an unknown number, called a variable, which in this case is substituted by the letter x.





Hope it helped,
