2 less then 3 times a number is 9

Masteriza [31]

$\huge\boxed{\text{As an expression:}\ 3x-2=9}$

$\huge\boxed{\text{Solved for x:}\ x=\frac{11}{3}}$

Let's start with " $3$ times a number". We will use $x$ to represent the number. $3x$

" $2$ less than" is next. $-2$

Finally, "is $9$ ". $=9$

Put it all together to get an expression. $\boxed{3x-2=9}$

Now, let's solve for the unknown number.

Add $2$ on both sides of the equation. $3x=11$

Divide both sides of the equation by $3$ to isolate $x$ . $x=\boxed{\frac{11}{3}}$

elena55 [62]

the arrow touches the ground when the heigth is 0

so we need to replace h=0 and solve for t

$\begin{gathered} h=17t-5t^2 \\ 0=17t-5t^2 \\ 0=t(17-5t) \\ 0=17-5t \\ 5t=17 \\ t=\frac{17}{5}=3.4 \end{gathered}$

the arrow tuches the ground at 3.4 seconds

$F=m\times a$

replacing

$185=m\times13.7$

solve for m

$\begin{gathered} m=\frac{185}{13.7} \\ \\ m=13.50 \end{gathered}$

the mass is 13.50Kg
