$\text{The two angles are supplementary, so their measures add up to 180 degrees.}$

$~~~~~~15x+105 = 180\\\\\implies 15x = 180 -105\\\\\implies 15x = 75\\\\\implies x =\dfrac{75}{15}\\\\\implies x = 5$

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

1.5c - 6 = 7.5 i need help with this problem and i have no one to help me

Lostsunrise [7]

Answer:

c=9

Step-by-step explanation:

Let's solve your equation step by step:

add 6 on both sides
divide 1.5 from the product of 6 and 7.5 (aka 13.5)
you will get C
put 9 in for C.

<h2> $1.5c-6=7.5$ </h2>

1. $1.5c-6+6=7.5+6$

1.5 $1.5c=13.5$

2. $\frac{1.5c}{1.5c}=\frac{13.5}{1.5c}$

3. C=9

1.5(9)-6=7.5

13.5-6=7.5
