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 $x$ . $x=\boxed{\frac{11}{3}}$

Answer:

(a) no solution

Step-by-step explanation:

Writing the second equation in slope-intercept form, it becomes ...

3x -y = 2 . . . . given

y = 3x -2 . . . . add y-2 to both sides

The first equation is already in slope-intercept form:

y = 3x +3 . . . . first equation

The coefficients of x in the two equations are both 3, so the lines they describe are parallel. They do not intersect, so there is <em>no solution</em>.

7. Susan spent 30% of the money she earned mowing lawns last summer. If Susan spent $51, what was the total

KatRina [158]

Answer:

$170

Step-by-step explanation:

30% of the money was equal to 51

so:

$\frac{30}{100} = \frac{51}{x} \\ \\ x = \frac{5100}{30} = \frac{510}{3} = 170$
