Given: -6x < 36.
Tpy6a [65]

Hii!

__________________________________________________________

\rightsquigarrow\circ\boldsymbol{Answer}\circ\leftharpoonup

x>-6

\rightsquigarrow\circ\boldsymbol{Explanation}\circ\leftharpoonup

Let's find the value of x in this inequality!

Remember, to find the value of a variable, we need to get that variable all by itself on one side of the equation.

Here all we need to do is divide both sides by -6.

\twoheadrightarrow\sf -6x\div(-6) < 36\div(-6)

\bullet <em>Simplify</em>

<em />\twoheadrightarrow\sf x > -6

\bullet <em>Note that the inequaiity sign changed. This happens everytime we divide, or multiply, both sides by a negative variable.</em>

--

\therefore, the\;answer\;is:\\\\\twoheadrightarrow\sf x > -6

\bullet <em>Great job! We solved the inequality.</em>

Hope that this helped! Best wishes.

Abby is half as old as her dad,and twice as old as her brother. If her brother is 9 years old,how old is her dad?
azamat
Well if Abby is twice the age of her bother and her brother is 9 then she is going to be 18 because 9x2=18, then it says that she is half her dads age so all you have to do is add 18+18 which equals 36

Levart [38]

Answer:

The answer is 5 ft squared

Step-by-step explanation:

so you have the find the area of the circle first and you do that by starting with the formula which is

pi r2

the diameter is 2.45 so you divide that by to to get the radius and get 1.25

the you would multiply 1.25 times 1.25 times 3.14, and get 4.91 which rounds to by the nearest whole umber as 5 ft 2.
