Answer:

x >-2

Step-by-step explanation:

We can add 4 to both sides.

Now the equation is -3x<2+4

Simplify to get: -3x<6

Divide by -3 to get x alone

x<-2

Flip the sign since you divided by a negative

x>-2

Answer:

0 and 3 are solution of inequality.

Step-by-step explanation:

Given  : -3x – 4 < 2.

To find : Which values are solutions to the inequality.

Solution : We have given

-3x – 4 < 2.

For x = -4 .

-3 ( -4) -4 < 2 .

12 -4< 2.

8 < 2

Which is false statement .

For x = -2 .

-3 ( -2) < 2

6 < 2

This is false statement so, this is not the solution of inequality .

For x = 0 .

3( 0) -4 < 2 .

-4 < 2

We know that negative value is always less than positive .

So, x = 0 is solution of inequality.

For x = 3

-3 ( 3) - 4 < 2

-9 - 4 < 2

-13 < 2

This is also he solution of inequality.

Hence there are two solution 0 ,3.

Therefore,  0 and 3 are solution of inequality.

Answer:

RADIUS

==================================

PROBLEM

Mary’s bicycle wheel has a circumference of 226.08 cm². What is its radius?

SOLUTION

We can solve this problem using the circumference formula in which π stands for ( 3.14 ), C stands for circumference itself and r stands for radius.

\bold{Formula \: || \: C = 2πr}Formula∣∣C=2πr

\tt{226.08 = 2(3.14) r}226.08=2(3.14)r

'Now to find the radius,Substitute 226.08 for c which is circumference in the formula.

\begin{gathered} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{C = 2πr} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{226.08 = 2(3.14)\red{r}} \\ \\ \: \: \: \: \: \: \: \: \large \tt{ \frac{226.08}{6.28} = \cancel\frac{6.28 \red{r}}{6.28} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt\green{C = 36}}\end{gathered}

C=2πr

226.08=2(3.14)r

6.28

226.08

=

6.28

6.28r

C=36

To check:

\begin{gathered} \small\begin{array}{|c|}\hline \bold{circumference }\\ \\ \tt{C = 2πr} \\ \tt{C = 2(3.14) (36\:cm) } \\ \tt{C = 2(113.04\:cm) } \\ \underline{\tt \green{C = 226.08\:cm }} \\ \hline \end{array} \end{gathered}

circumference

C=2πr

C=2(3.14)(36cm)

C=2(113.04cm)

C=226.08cm

FINAL ANSWER

If Mary's Bicycle has a circumference of 226.08 cm then the radius is 36.

\boxed{ \tt \red{r = 36}}

r=36
